Federer looked slow as the match started, but right when it counted he picked it up, and then delivered a 123-mph ace to Agassi. Federer has also won 14 of his last 15 tiebreaks. Not to mention a 84-3 record in the US Open since '03 or so.
The most dominating player in tennis history? you better belive it. when you can beat someone like Andre and his great history going back to the Andre/Sampras battles.
