I think it's incredible because there were guys like Mays and Mantle and Henry Aaron who were great players for ten years... I only had four or five good years. ↗
I was serving good but was returning especially well, which was a weakness in my game. So not only was I serving well, but I was also breaking these other guys, and they felt the pressure. ↗
Roddick can challenge him as well if he serves big consistently for the entire match. If he does that, then he is tough to break even for a guy like Federer. ↗
