Federer was equally untroubled in a 6-4 6-2 6-2 mauling of American Sam Querrey.

Seeking a record eighth Wimbledon singles title, the Swiss was on cruise control from the off.

On one rare occasion when he did find himself out of position he managed to manufacture a lob from between his legs that climbed over his 6ft 6ins (1.98m) opponent.

"So far so good," Federer said. "Sometimes the feeling is good out there and today was definitely a good day.

"I guess there's also a little bit of relief that I'm also playing well at Wimbledon."
