Good morning everyone and welcome to our live coverage of the fourth day at Wimbledon in SW19. Conditions are expected to be considerably cooler than what we experienced earlier in the week. At the moment South London is being blanketed in a fine drizzle, leaving Centre Court enclosed under its roof and the rest of the courts currently covered up.

We look to be set for a fine day of tennis as three of the supposed 'big four' in the men's category are all in action at some point today. Britain's Andy Murray is due out on Court One at around 1pm, while Roger Federer and Rafael Nadal are expected out a little later in the day. Murray is up against Robin Haase, Federer will be taking on American Sam Querrey and Nadal is due to face Dustin Brown on Centre Court at around 4pm.

In the women's draw we'll be paying close attention to second seed Petra Kvitova who will be facing up to Japan's Kurumi Nara in the latter stage of this afternoon. Sabine Lisicki will also be fighting for a third-round spot this afternoon, with her match against Christina McHale slated to get underway at around 1pm. These times are subject to change, however, given that Wimbledon is currently seeing a little bit of irritating rain. As it stands, the start of play has been delayed but we will be seeing some action sooner rather than later.

One of today's opening matches sees the mercurial James Ward of Great Britain taking on Czech player Jiri Vesely. The pair were meant to be starting bang on 1130 this morning, but the match has been delayed due to the weather. We'll let you know as soon as the game gets going. There is also another Briton in action at some point this afternoon in the shape of Slovenian-born Aljaz Bedene, who surprisingly ousted Radek Stepanek in the first round. British number two Bedene is facing the tricky Viktor Troicki today.

This evening should bring about some intriguing action too. The first round saw a memorable and long-lasting battle between French hopeful Jo-Wilfried Tsonga and Gilles Muller that lasted for the best part of four hours on Tuesday. Tsonga eventually came out on top after a strong showing of resilience from both camps, and the 30-year-old will now be facing Spain's Albert Ramos as part of Thursday's final offering of matches tonight.

WEATHER UPDATE! Positive news from across the courts... The sun is out and the covers are starting to come off. We are hearing that the majority of the 1130 matches will be getting started in around 25 minutes. Players are expected to take to the courts in about 15 to 20 minutes to begin their necessary pre-game drills.

Serena Williams secured progress into the third round yesterday after cruising past Timea Babos. The victory has established a clash with Britain's Heather Watson and the American legend has since been quick to highlight that she is wary of her looming opponent. You can read what the 20-time Grand Slam champion has had to say about Watson here.

American Querrey is facing Swiss legend Federer later on this afternoon and that clash should be an interesting one to observe. Querrey has often caused problems with his strong forehand, but questions around his mental strength have been asked after he has thrown away a number of games from winning positions in recent years. The players have not faced each other since 2008 and will be competing on Centre Court in a few hours.

One great benefit from the weather is that we might see an even greater uptake in the quality of tennis on show. With the weather being a little cooler, all of the competitors should have more in the tank. Hopefully we'll get to see some highly-energised performances this afternoon, which is an exciting prospect given that the majority of the men's 'big four' and the women's maestros are all in action.

Another interesting matchup today comes in the form of an early showdown between former world number one Caroline Wozniacki and Czech star Denisa Allertova. Wozniacki has often struggled against power from the baseline so she will be looking to get on the front foot against her opponent on Court 12.

Here's a quick snapshot from Twitter just to give you an idea of the weather conditions in South London at the moment. The covers are now off on all courts and the sun is starting to show just ever so slightly. We should be no more than about 15 minutes away from seeing some live action:

That image comes from Court Two where James Ward is just starting his walk out onto the court. This is a rather big game for the Briton who could seriously improve his ranking and future financial standing with a win against Vesely. We'll be keeping you up-to-date with all of the game's major developments, as well as all the other news from today's early contests.

Ward knows that this contest will be a tough one. The Londoner has been speaking about his opponent ahead of the game. You can read all that he's had to say about his plans for the match here.

Ward and Vesely are still in the processing of warming up, but elsewhere action is underway in all of the other 1130 games.

While we wait for some major developments from those fixtures, let's have a brief look ahead at our showpiece fixture at 1pm, where Murray will be going up against Haase. The British number one has faced Haase on five different occasions, winning the last four in a row. Murray suffered from cramps last time they met, however, as the Scottish star was dragged into a fourth set at the US Open last year.

Murray was given a good run for his money in the first round too having defeated Mikhail Kukushkin in straight sets. His Kazakh opponent made some impressive last-ditch attempts to drag the game into a fourth set, only for Murray's class to shine through at the vital moment. Following the contest Murray stated that he was "not surprised" by the quality shown by his first-round competitor.

UPDATE! An impressive start already then for 28-year-old Ward. He currently finds himself 3-1 up against Vesely on Court Two. Elsewhere, Magdalena Rybarikova holds a 4-1 first-set lead over Russian Ekaterina Makarova, while Wozniacki has raced into a 5-1 lead over Allertova and looks on course to take the first set comfortably.

Later this afternoon we'll be seeing Nadal taking on Dustin Brown. The two players will be facing up on Centre Court a little further down the line today, and Brown has been quick to insist that he will not be making any concessions or changes to his game ahead of the match. You can read what the German has had to say about the prospect of facing Nadal here.

UPDATE! We mentioned just a minute or so ago that Wozniacki had pushed out in front of Allertova. Well, the former world number one has just wrapped up the first set 6-1 and she now looks in commanding form against her Czech opponent.

UPDATE! Heading back to Ward now and the Briton has taken the first set against Vesely. Up at 5-2, Ward was 40-0 down before coming back to deuce and then claiming the game by forcing an error from his opponent to take the first set 6-2. Impressive work...

UPDATE! Rybarikova has also taken the first set against eighth seed Makarova on Court Three. The Slovakian star won out 6-2 in the first set after breaking impressively in the seventh game and finds herself in a dominant position going into the second set.

UPDATE! We've also got another men's game taking place over on Court Eight where France's Benoit Paire holds a one-set lead over Spain's Roberto Bautista Agut after a 6-2 shutout in the first. They're currently tied at two apiece in the second.

The time has come to head over to Court One now as we await Murray's clash with Haase. The clouds seem to have cleared and we now have some impressive-looking sunshine in SW19. This should make for an exciting matchup as Britain's number one looks to continue his push towards a place in the final. Last time these two met, they played out four sets in the US Open as Murray suffered from a number of cramping incidents. The 28-year-old looks in much better shape now, though, both physically and mentally.

Both players are met with great applause as they make their way out onto the court to begin practice. Murray is of course coming off the back of an impressive Queen's campaign and it's exciting to the Scot in such good physical condition. This commentary will now be focusing on the Murray match with game-by-game updates being given, while shorter snippets will be provided for all of the other games' major events.

Haase takes the first game with relative ease serving up against Murray who has very little in defence. The Scot loses the opening game without registering a point against his opponent, who forces Murray into an error on the forehand to wrap up game one in comfort.

Murray appears a little tentative but makes use of some clever approach play at the net to move 40-15 ahead of Haase, who is caught out by a cheeky forehand cut. Murray holds after some good footwork from Haase and the Dutch star eventually holes out at the baseline to hand game two to Murray.

BREAK! Haase calls for a challenge that goes against him as Murray moves into a 30-15 lead. Murray counters a poor volley from his opponent to bring up the break point. Haase just about hangs in there with a strong punch that moves the scores to 40-30, before Murray forces his opponent to overhit a return and achieve an important break to move 2-1 ahead.

That was comfortable for Murray, who takes another came completely unopposed this time. Murray opens up with an ace, before two errors put him in a commanding position. Andy does the job with a strong forehand winner to make it 3-1.

BREAK! Double break now for Murray who is looking incredibly impressive. Haase doesn't do himself any favours with a double fault off his first serve. Murray then goes on the attack with an impressive forehand, leaving Haase to buckle under the pressure with another error to put Murray in for the break. The Scot obliges with a neat backhand that does for the Dutchman.

Murray is marching towards claiming this first set. Haase makes four errors in a row to hand the sixth game to the British number one. The Dutchman struggled with two errors on the backhand and two on the forehand in that game.

SET! Haase is surely begging for the changeover, he's a bit all over the place at the minute and cannot seem to find the court. The players move to 30-30 after a few niggling errors, before Murray forces his opponent to crunch a smash into the net. Haase can't quite make a final return as he chips the ball beyond the baseline and Murray takes the first set with consummate ease.

UPDATE! We've had a result in the past few moments: Rybarikova has pulled off a shock 6-2 7-5 victory over Makarova and will now move into the third round of the tournament.

Murray takes the first game in the second set and seems imperious out there on Court One. He takes an impressive ace to make it 30-0, before Haase makes yet another error to hand his opponent the game after taking the Scot to deuce.

BREAK! More mistakes put Murray in control in game two and the Scot is presented with a third break point of the contest, which he takes with both hands after Haase smashes a woeful long-hop out of the back of the court.

Haase makes some decent improvements and moves 30-0 ahead having forced Murray to splice into the net. The Dutchman can't quite reach a wonderful forehand crunch down to the corner, however, as Murray battles back to achieve parity with the help of a strong serve. Haase doesn't seize the initiative despite being ahead at 40-30 as he whips one out to the side, leaving Murray to come back into the game with a strong service point. He finally wraps up the advantage when Haase fires into the net with a poor forehand.

Haase moves into a 30-0 lead after Murray can't quite keep a seemingly impressive return in the court, before another error from Murray makes it 40-0. The Scot registers off the backhand, but it doesn't matter too much as Haase takes the game with a service winner.

Back on his own serve, Murray regains some control after moving into a lead of 30-15. The Scot comes up with another impressive shot to force a backhand error from Haase, who has no reply again as his forehand fails him once more.

BREAK! The Dutchman needs to find some confidence somewhere and he makes two impressive serves early on as he forces a lead at 40-0, before chucking it all away as Murray battles back to deuce. Murray shows some aggression on the serve return to give himself an advantage, which he takes by squeezing the space with a strong pummel deep into the corner.

SET! There really has been no let up in intensity from Murray this afternoon and he takes the second set comfortably with Haase only being able to register once after an impressive rally and then after an error from the Scot. Murray clinches the set when Haase poorly chips into the net when there were clearly other shots on offer. Murray has been good, but Haase has been equally poor.

Haase has made a total of nine unforced errors in the contest, but it certainly feels like a lot more. The Dutchman takes a 30-0 lead after two impressive serves, only for his third to be called foul and Murray is brought back into the contest. Murray produces an error as the ball loops out the back and he can't return Haase's fastest serve of the game as the Netherlands star takes the game.

Where did that come from? Haase springs into action with two wonderful backhand shots to leave Murray looking a tad bemused off his own serve. The players are balanced at 30-30, before Murray produces the shot of the game to chip a drop-volley over the net and move ahead. He seals things with a commanding cross-court shot, which Haase spoons out of the area.

Wonderful from Murray again as he defends brilliantly to set up a standout attacking whip across the back of the court that completely does for Haase to make it 30-0 off the Dutchman's serve. A collection of errors bring the scores level, only for Haase to produce a shocking scoop that leaves Murray with a break point. Haase brings back deuce as Murray fails on the ground shot, and then pulls off an outlandish chip to take the advantage in his own favour. Haase saves the break and takes the game with a forehand winner.

Murray produces a fine moment of slapstick comedy with a thundering pound into the court at the net to make it 30-15 in his favour. Haase comes up short again on the forehand with yet another error. Murray then moves to close out the game as he tees up his opponent into a forced backhand mistake.

Britain's hopeful now produces a heavy ball down in the corner on the return, which Haase is unable to meet. With the scores tied at 30-30, Murray balloons a wide serve up into the air to put Haase 40-30 up. The Dutchman wins out when Murray crashes another effort out of the court. Great hold from Haase in that game!

The third set moves back level at 3-3, this time as Haase is undone by his own mistakes yet again. With Murray sitting 40-30 out in front, Haase balloons another return into the skies and the Scot levels proceedings in what could be the final set of the match.

BREAK! Could this be the turning point in this third offering? Murray pushes 30-0 in front off of Haase's serve, but the Dutchman digs in to battle back to to 30-30 with a commanding second serve that Murray is unable to return properly on the front foot. Murray is handed a break point as Haase poorly fails on two serves. Murray takes the game as his opponent whips another terrible shot out on the right-hand side.

Murray has the finish line in sight now as he looks to clean things up on Court One. The Scot is far too fluent to be troubled having guided a batted forehand across the court beyond the reach of Haase to make it 30-15. Murray storms the net for another comedic smash to make it 40-15, before Haase misfires again on the forehand with another mistake to hand the eighth game to Murray.

Beautiful from Murray as he rushes forward to take the ball on in flight and his commanding forehand sees no reply from Haase at 30-0. His counterpart battles back strongly to move 40-30 ahead with the help of a superb ace. Murray then comes up short on the return to give the game to Haase. He'll still be serving for the game now, though...

GAME, SET & MATCH! A booming forehand from Murray sees him open his account in the tenth, and he soon adds to that with another standout chip that cuts Haase in two as he tries to rush the net. He tees up the final point at 40-0 after teasing Haase towards the net again, before Haase replies by forcing him into a forehand error. Murray wraps things up at the next time of asking, however, as the Dutchman can only return meekly into the net. Britain's number one coolly moves into the third round...

So Murray books his place in the third round with relative ease. The Scot produced some wonderful shots in that contest, but you have to say that he was almost gifted that game by Haase who made far too many errors. The Dutchman fought back only to be able to muster a form of resilience that could best be described as sporadic.

UPDATE! We've had some more results in the women's matches from earlier today. As mentioned, Rybarikova has moved into the third round, but so have Wozniacki and Angelique Kerber. Former world number one Wozniacki beat Denisa Allertova 6-1 7-6, while Kerber held firm to see off Anastasia Pavlyuchenkova 7-5 6-2.

UPDATE! Britain's Ward is still battling it out with Vesely over on Court Two for a place in the third round. The 28-year-old is just two games away from a historic place in the next stage of the SW19 showpiece; he currently leads 6-2 7-6 (7-4) 3-6 4-1.

Our next live commentary will bring you game-by-game updates from Centre Court as Federer takes on Querrey of the United States. We're just waiting for Sabine Lisicki's game with Christina McHale to come to a conclusion.

RESULT! And there we go... despite going 6-2 down in the first set, Lisicki has rallied back to take the second and third sets 7-5 and 6-1 respectively to secure progress into the next stage. Just for confirmation, that's a 2-6 7-5 6-1 win for Germany's Lisicki.

RESULT! We have got word of another fantastic result for Britain this afternoon as James Ward has now booked his place in the third round of the men's draw. He's secured a historic 6-2 7-6 (7-4) 3-6 6-4 victory over Jiri Vesely. That result could have profound ramifications on the 28-year-old's future in the game.

British number one Heather Watson is due to face the legendary Serena Williams in the third round, and she has been speaking about her approach to the upcoming fixture. The 23-year-old has insisted that she will not be overawed by the prospect of facing the 20-time Grand Slam champion.

RESULT! We have a result coming from the men's side of the game, as Roberto Bautista Agut has just won out after a five-set marathon with France's Benoit Paire with a 2-6 4-6 6-3 6-3 6-3 victory.

We're now moving our attentions over to Centre Court where Swiss favourite Federer is taking on America's Querrey. Stick with us for live game-by-game updates...

The American starts with two impressive attempts on the serve to take a 30-0 lead over Federer. Querrey takes the game after his Swiss counterpart produces an error on the forehand as he looks to return.

Some brute force courtesy of Querrey sends him into a 30-15 advantage, before Federer bounces back with an impressive forehand winner that leaves his opponent speechless. Federer can't quite make the forehand as he crashes the ball into the net, but returns to claim deuce with a wonderful ace. Querrey fails on the return as Federer pushes back in front with an advantage, but more expressive play sees Querrey pull level. Federer sends the games level by eventually forcing his counterpart into a poor high scoop.

Querrey's strength is showing in these early stages as he moves into a 2-1 lead. The American's serve has looked wonderful so far and he pulls out in front with Federer unable to register much in the way of resilience in game three as he concedes without scoring.

You get the sense that Federer is just sizing this challenge up at the moment. The Swiss comes on strong off his own serve to move 40-0 in front, before conceding with a poor forehand that is whipped out of the court. He finally finishes things off with an untouchable forehand that flashes right across the face of Querrey.

Federer falls 30-0 behind, but pulls 15 back with a strong forehand volley on the approach that sends the crowd into applause. Querrey eventually proves too strong off his own service and the game ends as Federer sends an error out the back of the court.

Querrey looks a tad embarrassed as he spoons a horrific return into the Gods, but he soon returns with a stunning forehand thump down the line to bring the scores level. Federer edges in front at 30-15 following a backhand error, before going on to close out the game by forcing the American into two consecutive backhand mistakes.

Querrey's service seems particularly strong at the moment and he delivers a beauty that does for Federer, who can only send a return out of the guidelines at 30-15. Querrey takes the game with a nice combination of forehand and backhand points to take a 4-3 lead after seven games.

Federer's forehands appear to be kicking up on Querrey a little, who goes 30-15 behind with another ballooned shot. Federer has a little too much for him with another strong forehand down the line. He finishes the game off with a volley over the net that proves too much for his opponent.

BREAK! We're into the business end of the set now and Federer does what he does best: applies the pressure... The Swiss moves 30-0 in front before moving to break point with a wonderful forehand to shorten the swing. Querrey displays some great resistance as he battles back to take an advantage despite Federer having three break points in hand. After a second deuce, Federer moves back for a fourth break point after a mistake from Querrey. Federer achieves the break with a standout backhand smash.

SET! Game ten begins with an intriguing forehand rally, which ends in favour of Querrey, only for two errors to give Federer the lead on his own service. Querrey is unable to return the serve as the scores move to 40-15, leaving Federer to finish the job as the American cannot muster a response for the second time in a row.

BREAK! Querrey has his back to the wall early on in the second set, with Federer leading at 30-15. The Grand Slam extraordinaire pulls off a wonderful smash across the face of the court to make it 40-15. A break is then achieved as Querrey scoops his shot wide from the net as Federer forces his hand with a rush towards the mesh.

Federer produces a few mistakes off his own serve as the scores move to 30 apiece. The number two seeded player then rushes and slams the ball into the court to take the lead, before good work sees Querrey pull level at deuce. Federer moves back in front as the American's return slips out the back of the grid, leaving Federer to take the game with a sneaky shot short at the net.

The pressure is now purely on Querrey as he tries to survive a potential double break. He takes to the task with an air of grace as he pushes into a 40-0 lead, but a high scoop lets Federer back into the game at 40-15. Querrey isn't moved, however, as his cut leads to an error from Federer, who forces an effort wide of the court.

Federer knows just when to turn it on, doesn't he? He moves on unopposed to 40-0 with an array of shots that have Querrey wondering what he can even do to stop them. Federer seals the game as Querrey fails to return with his forehand.

Off his own serve, Querrey is able to move out in front, before he is pegged back by some neat cutting work from Federer. Querrey shows some decent resolve, though, as two strong shots put the game back in his favour as the American takes game five with a service winner.

More class work from Federer now as a foray forward sees the world number two showcase shots like he's at an exhibition game. With things standing at 40-15, the 33-year-old wraps things up with a serve that sees Querrey spoon his return out of bounds.

BREAK! Wow... Ridiculous tennis from Federer who produces a return through his legs that lobs Querrey to take a 15-0 lead. The American isn't too fazed and some strong work puts him in front at 30-15, only for him to surrender parity to a shot that sees Federer send a standout forehand across the court. Break point is then offered up as Querrey sends one into the net, but he stays in the game by clawing back deuce. A lucky shot that tips just over the net sees Federer move back in front, and he soon seals the break with Querrey double-faulting on his serve. Federer is now serving for the second set.

SET! A couple of dodgy efforts from both men see the scores sitting at 15-15 and Querrey sends another out of the court to put Federer slightly ahead. The veteran fails to look back as he nips forward to splice at the net and make it 40-15, before cleaning up with a memorable ace to take the set and put himself in a commanding position for progression.

BREAK! Federer shows wonderful pace now to move ahead early in the third with a terrific forehand down the line. Querrey levels things with an equally good backhand that is whipped neatly across Federer's view. The underdog moves ahead at 40-15 only to see a persistent Federer move forward on the front foot to bring things to deuce. The veteran takes the advantage and eventually seals the break with a clever return that has Querrey scrambling to force a shot that cannot climb over the middle.

Federer continues his march to what surely seems like a place in the third round with Querrey only able to register one point against the dominant Swiss maestro in the second game of set three.

This is dangerous ground for Querrey as he toys with the prospect of a double break in the third. Federer has two chances to take the break, but he fails on the second having completely missed the ball with a reckless swipe. Querrey then moves ahead after deuce and clings on for dear life as Federer scoops wide to surrender the game despite originally being in a very strong position.

Back in the comfort of his own serve, Federer moves unchallenged to 40-0 with a couple of forehand winners and a mistake from his opponent. He finishes things off by pushing Querrey into a backhand error.

Querrey isn't quite done yet, though, and he takes the fifth game with consummate ease by showcasing some standout strength off his own serve and first return. It's probably a little too late for the American, but that was a wonderful display of confidence from Querrey. He'll need plenty more of that if he's going to secure the three straight sets he needs to win this game.

This contest has been a great workout for Federer by the looks of it, he's demonstrated some great craft across all parts of his game including both the forehand and backhand, as well as his rushing and sitting. He squeezes out game six off his own serve despite some admirable resistance from Querrey.

BREAK! Federer smells blood and the prospect of a vital break, but he doesn't count for some strong service from Querrey who takes a 30-15 lead after a timid opening. Federer moves back level when his opponent finds the net, before sneaking in front with a dominant forehand smash into the corner. Deuce is reached as Querrey hustles hard after an impressive rally, only to surrender with a forced mistake close to the net. Federer kills the game off with some brutal forehand work that leaves Querrey unable to return from deep in the corner. He's now serving for the game...

GAME, SET & MATCH! Some awkward play and a number of mistakes leave proceedings at 30-15 in favour of Federer, who then splices poorly out the back of the court to bring Querrey back into the game with the scores level. Querrey moves ahead for the break point, but is wasteful by stroking out of play. Federer doesn't let it slip at deuce and he moves back ahead with his opponent unable to return. He serves for the match and clinches victory when Querrey spoons the return out of bounds.

There we have it then, another fairly easy victory from one of the members of the supposed 'big four'. Federer has guaranteed his place in the third round at the expense of Querrey, who just didn't have the required control in the vital moments of the game.

UPDATE! During that contest we've seen other results elsewhere. Women's pacesetter Petra Kvitova eased herself into the third round as she came out on top with a comfortable 6-2 6-0 win over Japan's Kurumi Nara. In the men's game, Gilles Simon also booked himself a place in the next round with a 6-1 6-1 6-7 6-1 victory against Blaz Kavcic.

RESULT! We've now got news of a surprise giant killing in SW19 as Feliciano Lopez has just been defeated in memorable circumstances by Georgian underdog Nikoloz Basilashvili. The Georgian got past his opponent having achieved a 7-5 3-6 6-3 2-6 6-4 victory across five sets.

Rafael Nadal is just making his way out onto Centre Court ahead of his contest against Dustin Brown. We'll be providing full game-by-game coverage of that contest too. Murray has done it, Federer too; can Nadal earn progression into round three? His match will be underway in the next 10 minutes or so.

It's time for me to head off now, but I'll be leaving you in the hands of Shane Callaghan who will be taking you through Nadal's contest with Brown this evening. Over to you then, Shane...

Brown* 1-0 Nadal! Thanks Chris. Good evening folks and welcome to our live commentary of Rafa Nadal's third-round match with Dustin Brown. We've just kicked off and the first thing to note is that Mr Brown has some excellent hair. Think Bob Marley. Top drawer.

Brown 1-1 *Nadal! Nadal, in his 11th Wimbledon, levels up the first set at one game apiece with an ace to win the game. It's been five years since he's won here so, you know, he'll want a big tournament this time around.

Brown* 1-2 Nadal! He wasted no time there, did he! The Spaniard forces the first break point of the game to move 2-1 ahead by winning four successive points. Having seen Murray, Federer and Djokovic all seal their place in the third round, Nadal will be keen to joy them and he looks in form thus far.

Brown 1-3* Nadal! Best game of the set thus far. There's something very Dennis Bergkamp about Brown, who likes a nonchalant little lob as much as the next man, but he's a bit Heskey when it comes to executing them properly and Nadal pounces on the mistakes to move 3-1 up. You get the feeling that neither of these are in full flow as of yet.

Brown *2-3 Nadal! That's a little more like it from Brown, who finds the range on those little lob shots of his to preserve his break and reduce the arrears. He's ranked 102 in the world, the German, but he looks a capable player so far. That backhand is frightening quick.

Brown 3-3* Nadal! How about that for a response! Brown wins four successive four points in the sixth game to level up the match and break back. This one looked easy for the Spaniard on paper but it's proving anything but.

Brown 4-4* Nadal! Nadal, who lost the previous game on Brown's serve, holds his service game, slamming an ace past the German to level up the first set. Nadal hasn't fared well at Wimbledon in recent years and Dustin Brown could yet become the latest lower-ranked player to upset the former world number one.

Brown *5-4 Nadal! Brown moves 5-4 with perhaps the shot of the game! The German looked certain to lob Nadal, but instead he plays a deft shot to the right of him to decieve his Spanish counterpart, before serving another ace to take the game. We compared him to Dennis Bergkamp a little earlier and he certainly has that confidence and audacity about him.

Brown 5-5* Nadal! This is steel meets silk, with Nadal representing the former element in this game. He draws level in the set, forcing Brown into a number of over-hit shots - ones that you wouldn't believe were in his repertoire based on his earlier efforts. You get the feeling that Brown has to win this first set.

Brown *6-5 Nadal! Huge game there by Brown. We said he needs to win the first set to stand any chance of eliminating the Spaniard and, well, he may be on the brink if he can break Nadal again.

SET! Brown 7-5* Nadal: What a massive break by Brown, who makes good on his set point by ferociously returning Nadal's serve in an incident that saw Nadal hit his own foot instead of the ball. That's how fast it came back at him! Brown is the real deal, my friends. What a set.

Brown 7-5 *1-0 Nadal! Indeed, Dustin Brown kicks off the second set with the same resilience evident from the end of the first set. There a couple of deuces there after Nadal fought back gamely, but Brown kept his cool. Still, there's a long, long way to go in this folks.

Brown 7-5 1-1* Nadal! Not being commanding enough on his own serve is what saw Nadal lose the first set, having surrendered his serve on two occasions, but his service game looked better just then as he levels up the set.

UPDATE: Elsewhere, Jo-Wilfried Tsonga has booked his place in the third round with a straight-sets win over Albert Ramos, while Tomas Berdych and Gael Monfils, both two sets up, look good to join him.

Brown 7-5 1-2 Nadal! Massive from Nadal, who breaks Brown's serve to establish a big advantage. Still, this Brown certainly isn't the type of character lacking a bit of confidence. He's like Dimitar Berbatov, Dennis Bergkamp and Bob Marley wrapped in one. Really interesting player.

Brown 7-5 1-3* Nadal! Nadal is slowly but surely growing in authority here and the panache from Brown that made the first set so interesting seems to have eluded him here. Where's the chips? The deft shots bordering genius? The lobs?

Brown 7-5 *2-3 Nadal! That was important by Brown, who holds his serve this time to move within one game of parity. He still needs a break, but having broken Nadal twice in the opener, you wouldn't back against him. If he can find the form that Nadal struggled badly with earlier then he's got a real shot at moving two sets up.

Brown 7-5 2-4* Nadal! This is what happens when Brown's lob shots go wrong! It was awful, and it was the point that helped Nadal hold his serve to re-establish the two-game cushion. It reminded me a 'flop shot' I played in golf earlier. I tried to lob it up and have it plonk on the green, but it went around four miles past the pin. That's the price geniuses like Brown and I pay for trying to entertain. Anywho, back to Brown, who is serving to stay within reah.

Brown 7-5 *3-4 Nadal! Yep, the German is staying within touching distance of Nadal here by cruising to victory on his own serve. That was massive, because defeat would've left Nadal serving for the set. This is a fantastic match so far.

Brown 7-5 3-5* Nadal! It certainly seems as if we're going one set apiece here. Nadal is 5-3 up and a break of serve now will see him secure parity in the contest. The Spaniard still isn't at his best, but for the moment he's doing enough to slow Brown's roll.

SET! Brown 7-5 *3-6 Nadal: We said Nadal was slowly but surely getting back, and he's just levelled up the match at one set apiece after breaking the Brown serve. Interestingly, the Spaniard is also getting gradually more animated and passionate as the contest rolls on - and that can't be good for Brown.

Brown 7-5 3-6 0-1* Nadal: Nadal holds his serve with an ace after Brown fought back to preserve deuce, but the Spaniard moves one-up. You get the feeling that the longer this goes on, the less confident Brown will feel about his hopes of a giant killing. Still, who knows.

Brown 7-5 3-6 *1-1 Nadal: Brown holds serve, reproducing the kind of deft drop shots that we saw from him throughout an excellent first set. He's got them in his locker, and the entire crowd knows it by now, but my criticism of him is that he uses them at the wrong time. They've served him well overall, but learning when and when not to execute them will benefit him hugely.

Incidentally, Brown's trainer looks a little like Lembit Opik, which could be construed as a massive, massive insult.

UPDATE: Pretty much all the big boys have gotten through their second-round games today, with the exception of Feliciano Lopez, but beyond that no major giant killings. Which way will this one go?

Brown 7-5 3-6 *2-2 Nadal: Yep, Brown levels up once more. We're yet to see a break of serve as of yet. That's what led to the first two sets for each player, but both are far better on their service game thus far in this third set.

Brown 7-5 3-6 3-2* Nadal: Massive, massive break by Brown, who moves 3-2 ahead in a truly poor fifth game by Nadal, who endured back-to-back double faults to give the German break point, and Brown took full advantage with one of those deft close-range efforts that left Nadal needing to cover about 15 metres in a matter of seconds. Huge.

Brown 7-5 3-6 *4-2 Nadal: Brown is playing some excellent, excellent tennis again to establish daylight in the scores by moving 4-2 up in the third set. If he holds his serve then he goes one set away from a massive, massive upset. He's been brilliant today overall. Dennis Bergkamp meets Bob Marley.

Brown 7-5 3-6 4-3* Nadal: Probably, and definitely, the biggest game of the match so far. Brown has two break points missed as Nadal scraps his way back to within a game of parity. The clincher trickled over the net to leave Brown with no chances. Nadal has had to dig deep in this game, which is testament to Brown's performance.

Brown 7-5 3-6 *5-3 Nadal: Both players really, really want this now, but Brown is the one that looks like grabbing the second set as he moves 5-3 ahead. We saw two exhilarating rallies - probably the first two of the game. Nadal is running out of ideas.

Brown 7-5 3-6 5-4* Nadal: Nadal isn't messing about on his own serve, as he returns to within one game of parity. But Brown is now serving for the second set! His coaching staff are living every shot - hitting every ball.

SET! Brown 7-5 3-6 *6-4 Nadal: Yep, Dustin Brown is just ONE set away from eliminating Rafael Nadal. There's lots of glum faces in the crowd, no doubt realising that their hero Nadal could be heading out, but Brown has been brilliant. He's a cool dude this bloke and nobody can begrudge him if he gets past Nadal here.

Brown 7-5 3-6 6-4 1-0* Nadal: Lord knows how this bloke is 102 in the world. He's having a blinder here. No doubt the occasion has fuelled him, but Brown breaks Nadal straight away in the third and potentially FINAL set. What a shock this would be. Having said that, Nadal exiting Wimbledon in the early stages isn't anything new, but I'm not sure any of his previous tormentors here in recent years have played to Brown's standard.

Brown 7-5 3-6 6-4 *2-0 Nadal: He's just four games away from a spot in the third round. Simply put - if he holds his serve then Nadal goes out. Simple as. Nadal has won A LOT of different competitions, and he needs to call on all that experience here because he needs to dig deep. Very deep. He needs to get halfway to China.

Brown 7-5 3-6 6-4 2-1* Nadal: Nadal holds his serve, but it was anything but straight forward. He's really labouring here folks. Brown must be absolutely terrified. He's four games away from the biggest win of his professional career and his heart must be beating as fast as I don't know what. Nadal can use that anxiety to his advantage.

Brown 7-5 3-6 6-4 *3-1 Nadal: Make that three games away from the biggest win of his 13-year career. He emphatically holds his own serve to take one more step to a giant killing.

Brown 7-5 3-6 6-4 3-2* Nadal: Nadal holds his serve. Brown pushed him very close but the Spaniard won moved back to within a game of parity when Brown's wild backhand flew well out of bounds. Now, the German serves to go four up and two adrift of a huge win. If Rafa plans a comeback then he better stage it soon.

Brown 7-5 3-6 6-4 *4-2 Nadal: Brown is playing like a man who knows that holding his own serve is the key to seeing out this game. He's just cruised into a 4-2 lead on his serve, whereas Nadal has to work really, really hard in order to hold his service game. What a performance.

Brown 7-5 3-6 6-4 4-3* Nadal: Nadal is back to within one. The aim for Brown is simple: hold your serve and you're into the third round mate. Easier said than done, of course, but Brown looks like he's made of strong stuff.

Brown 7-5 3-6 6-4 *5-3 Nadal: Brown is a different animal on his serve and he's now just ONE game away from a place in the third round. Nadal needs a miracle with the way in which Brown is serving.

Brown 7-5 3-6 6-4 5-4* Nadal: Oh my oh my. Nadal fights back from two match points for Brown to stay alive. But now Brown is coming out to serve out the match - and we know how ridiculously brilliant he's been on his service game so far.

GAME, SET & MATCH! A truly phenomenal performance from Dustin Brown sees the German knock out Rafael Nadal in the second round!

Brown holds his truly excellent service game one last time, serving out an ace to beat Nadal 7-5 3-6 6-4 6-4. He's 102 in the world, but don't be fooled by his ranking because the Bob Marley lookalike with the touch and nonchalance of Dennis Bergkamp is the real deal.

What is it about Nadal and Wimbledon? He hasn't won the competition 2010 and has been the victim of a giant killing in recent years - but did any of those tormentors of recent years play as well as Dustin Brown? That's debatable.

So, Nadal and Feliciano Lopez bow out, but the likes of Federer, Tsonga, Murray and of course Brown march into the third round. Wimbledon is fantastic, isn't it?

That concludes our coverage of Wimbledon on day four, but join us tomorrow for the beginning of round three. There's some very tasty match-ups to observe there. Until then, see you folks!
