I like him. Haven't seen him at the Open yet, but I've been keeping up with his matches and seeing that he's been doing really well. I remember him from the Open a few years ago when he played Roddick. He did really well (Roddick still won), so I figured I'd keep him in mind since he could be the future of American tennis. Ryan Harrison and John Isner both have better shots at that title, but if Sock continues to do well....who knows? Luckily I'll be able to watch his match tomorrow (or technically today I guess) so I'm excited.
