Roger Federer continued his quest for a ninth Wimbledon title with a comfortable 6-3 7-5 6-2 win over Jan-Lennard Struff in the third round.
The top seed, who is yet to drop a set at this year’s championships, did not relinquish a single break point during the 97-minute domination.
"Against big servers who go for a lot it's always difficult to find rhythm and be sure that you are in driver's seat until the match is over," Federer said.
"I was happy to stay clam and finish off the job. I thought I did very well today. I created more chances in the second set and was always able to stay pretty clean on my own service game.
"It's a wonderful feeling walking out there, I take every match one at a time, I try to put on a good match, try hard every time, and will never underestimate anybody - that keeps me in check."
France’s Adrian Mannarino, a five-set winner over Daniil Medvedev, awaits in round four. On this evidence, his hopes will not last long.
