Serena and Venus Williams had different fortunes in their respective third rounds at Wimbledon on Friday as the former defeated Kristina Mladenovic 7-5, 7-6 (2) to advance to the last-16, but the latter fell to Dutchwoman Kiki Bertens 6-2, 6-7 (5), 8-6.

It was Bertens’ first-ever top-10 win on a non-clay court and it put the No. 20 seed in the fourth round at the All England Club for the first time in her career.

Roger Federer defeated Germany’s Jan-Lennard Struff 6-3, 7-5, 6-2 to post a 175th career victory on grass, an all-time record by any man, moving one ahead of Jimmy Connors.

10th-seeded Madison Keys suffered a shock upset against Evgeniya Rodina 7-5, 5-7, 6-4, but No. 7 seed Karolina Pliskova escaped a similar fate by defeat Mihaela Buzarnescu 3-6, 7-6 (3), 6-1.

Gael Monfils reached the fourth round at Wimbledon for the first time in his 10 career appearances by defeating last year’s semi-finalist, No. 11 seed Sam Querrey 5-7, 6-4, 6-4, 6-2.

On his decade-long quest for a Wimbledon second-week showing, Monfils said: “It was for sure long. But I think it took me years and years. Also had to put myself in a good opportunity, to put myself in a good balance with my body and my believe on a grass court. Then, as I say, the last three years were much better. I just couldn’t I think take the opportunity. Today I took it and I’m happy about it.”
