Five-time winner of the Cincinnati Masters event, Roger Federer proceeded into the third round of the Western & Southern Open by defeating Philipp Kohlschreiber in straight sets (6/3 7/6).
Federer had been testing a new 98-square-inch head racquet following an early Wimbledon exit, but reverted to his usual 90-square-inch Wilson for his opening match against Kohlschreiber.
“I’m going to do more racquet testing when I have, again, some more time after the US Open. I was playing for a month with the black one, but it’s a prototype. At the end, I just felt like, you know what, right now I feel like I need to simplify everything and just play with what I know best,” stated Federer in the post-match interview.
The former world number 1 and 17-time major winner also announced he’d got through the match without any back pain. He has been suffering from recurrent back spasms during the year.
