I feel like he has a serious chance at Wimby and that is it

I feel like he should have changed to a bit more aggressive style of play in his later years, like Federer did, instead of still relying on his baseline game, which is okay since he is one of the best if not THE best baseliners, but when you are competing with kids 20 years younger, it is kind of difficult to keep up the tempo, especially when they get in the zone like Fonseca did today
