Roger Federer reached yet another landmark as he swept into the last 16 at Wimbledon.

The Swiss' straight-sets victory over Lucas Pouille was his 350th at a grand-slam event, a landmark no other player has reached or even come close to.

Federer said: "The records mean something to me, but not everything just because I am very much aware that not everybody for the last 100 years played all the slams.

"It's really only the last 20 years that that's been going on. Travelling has got easier. I'm sure that's going to keep happening from now on, most of the players will keep playing.

"Of course, I hope it's going to take a special performance from somebody to stop me, not just a mediocre performance."

Federer will now meet Matteo Berrettini on Monday as the tantalising prospect of a semi-final with Rafael Nadal looks increasingly likely.

Britain's Dan Evans was unable to set up a fourth-round clash with Nadal as his campaign ended with a heartbreaking five-set loss to Joao Sousa.

Evans is ranked eight places higher than his opponent and this looked to be a great chance for the British number three to reach the last 16 for the first time but he fell to a 4-6 6-4 7-5 4-6 6-4 defeat after three hours and 56 minutes.

It was a contest full of tremendous shot-making, the power of the Sousa forehand against Evans' all-court talents, but the 29-year-old paid for not converting his early dominance and taking only seven of 24 break points.

Kei Nishikori brought up his 400th win on the main tour as he eased past American Steve Johnson.

The Japanese, seeded eighth, posted a 6-4 6-3 6-2 success first up on Court Three.

Sam Querrey, the 2017 semi-finalist, is back in the second week after a 7-6 (3) 7-6 (8) 6-3 victory over John Millman

Mikhail Kukushkin matched his best ever grand slam win with a four-set victory over Jan-Lennard Struff while Berrettini won the longest match of the tournament so far, beating Diego Schwartzman 6-7 (5) 7-6 (2) 4-6 7-6 (5) 6-3 in four hours and 19 minutes.
