Federer continues to set the standard at SW19 as he cruised past Struff in just one hour and 34 minutes.

The Swiss star was rarely tested and heads into the fourth round yet to face a break point, per Live Tennis:

The 36-year-old took just 24 minutes to take the first set 6-3, and although the second was tighter, he managed to clinch the crucial break at 6-5, which allowed him to serve it out.

Struff came into the match on the back of five-set wins over Leonardo Mayer and Ivo Karlovic, and he visibly began to tire in the final set.

Federer gained a double break to take it 6-2 and notch up a new record on grass, per ESPN:

The top seed was a cut above throughout the match and looks in great shape to retain his title. He will play the No. 22 seed Adrian Mannarino in the fourth round.

Also into the fourth round is Serena Williams, who is growing into the tournament and fully deserved her win over Mladenovic.

The American, who is playing at Wimbledon for the first time since returning from maternity leave, recovered from going a break down in the first set that left her trailing 5-3.

She won four straight games to clinch the opener 7-5 and then carried that momentum into the second set as she broke again. However, Mladenovic managed to level the tie and also saved a match point to force a tiebreak.

Again Williams stepped up her game when it mattered to win the set and progress to the fourth round without dropping a set.

The former champion said afterwards she is ready for anything:

The women's draw has opened up with eight of the top 10 seeds having already been knocked out. Williams looks to be improving with every game and has a real chance of claiming an eighth singles title at Wimbledon.
