stan has come a long way.
he has such a huge serve and he has significant power off both wings.
he has worked hard on his fitness the last 2 years
He has, but I'm starting to get a little wary of Kei. It seems like in the biggest matches he kind of doesn't show all the way up. It's like he's great throughout the tournament, but at the business end he doesn't look like the same player. Maybe it's me (I hope so). I really enjoy his game.
