Plymouth Argyle have gone four points clear at the top of League Two thanks to Ryan Brunt's late winner against Luton Town, while second-placed Portsmouth were held to a goalless draw at home to Mansfield Town.

Carl McHugh glanced in Craig Tanner's right-wing cross to give Plymouth the lead away to Luton but Josh McQuoid's free header in the 76th minute brought the Hatters back on level terms.

Barnet scored three first-half goals in six minutes to stun United as Curtis Weston, John Akinde and Josh Clarke all hit the back of net.

Sercombe recorded his and Oxford's second right before half time to bring his side back into the tie but it was not enough for Michael Appleton's charges as they were defeated to leave them in third, only ahead of Northampton Town on goal difference.

Northampton moved into fourth spot with a 2-1 victory over Stevenage, who took a first-half lead with Steven Schumacher's first goal for the club.

Dominic Calvert-Lewin got the final touch on a David Buchanan cross to level matters, before substitute Alfie Potter comverted the winner by sliding in and blocking a Stevenage clearance straight into the net.

Seamus Conneely rifled home from 12 yards out, after Dagenham & Redbridge failed to clear a corner, to give Accrington Stanley a one-goal advantage after two minutes of the tie.

Cambridge United's Rory Gaffney nodded a fourth-minute header past Yeovil Town keeper Artur Krysiak from Barry Corr's knockdown, recording his brace 20 minutes later with a close-range finish.

On-loan Josh Sheehan hammered in a second for the Glovers but it was too little too late as they were defeated at home by United.

Newport County took a fortuitous lead against Bristol Rovers as Tom Parkes headed a cross into his own net but Rovers were soon back in the tie as Billy Bodin responded for the hosts in the 15th minute.

On-loan Charlton forward Zak Ansah took advantage of Rovers keeper Lee Nicholls dropping the ball in his own penalty area to tap home early in the second period, before recording his brace a minute later with a left-footed volley that flew into the top corner.

Ansah then turned provider, setting up Tommy O'Sullivan to power in from the edge of the area for County's fourth in a comprehensive victory which saw them move out of the relegation zone.
