Federer was doing so good. a little inconsistent off the ground but he was making progress.
I am really in disbelief. he should have been able to solve wawrinka on clay in the best of 5 sets match.
his backhand let him down. that cost him big time on the return of serve too. wawrinka saw that Federer was struggling off his backhand wing so he directed most of his serves to that wing.
on another note: this shows what fitness can do. wawrinka is 30+. his average speed on his first serve was 130 MPH.
he was hitting forehands at 100 MPH and hit one backhand at 93 MPH from well behind the baseline.
he is spending time in the gym. he basically overpowered Federer with his physicality.
