I voted for Marat, but my favourite players weren't up there so I'll add them now.
Haas is gorgeous, Feliciano is SO pretty (don't you wanna just play with his hair?), Gonzalez is pretty cute also, Djokovic is alright, but I don't like him that much as a player (but good job at Indian Wells, even if he didn't play any great players, top ten now). Andy Roddick I used to love when he had that beard for some reason, which is so lame, but I though he looked like a hobo, and it cracked me up, but now I just find him annoying. And I'm so glad he didn't win Indian Wells, 'cos I couldn't stand the American commentators going on and on about how he's "closing the gap" like in Cincy last year. James Blake annoys me becase he used to be so hot, but then he shaved hi head, and it was a really stupid thing to do.
But I reckon the hottest tennis player, without a doubt is Richard Gasquet. Gasquet Gasquet Gasquet! He's so sweet, and his backhand? Oh. My. God. That is the sexiest shot in tennis today.
