I'd love to see Roddick win. He's been a finalist there 2 or 3 other times but fell short, especially in 2010 or 2009 to Federer in a 5th set 13-15 tiebreak loss. Too bad he's definitely been lacking in play lately; but grass is his best surface. I like him because you can always expect to see him talking shit to the ref or breaking racquets.
But it will most likely be Nadal, Murray or Fed. I'd like to say Djokovic but his 43+ win streak is over, I just don't see him bouncing back that fast.
