I'm a huge Federer guy, but I'd really like to see Roddick pull it out. He's gotten way too much criticism in the past....most of it unfair IMO. He's looked like a completely different player in this tournament.
Federer hasn't had an advantage in any game where Roddick was serving the entire match, and he himself has 44 Aces. This has been so awesome to watch. These guys are gonna serve at each other all day long.
