US Open 2009 Flushing Meadows

I've really taken a liking to both Cilic and Del Potro this tournament. They both seem very likeable and i like their games too.

Obvioulsy still want Federer to win this in 4. Getting tight.
 
The mens game is in such good shape right now. All these youngsters aren't one trick poneys at all, they all move so well and have such a variety of skills.
 
I cant see this going to a fifth set now. I'd love it if it does.
Surely Del Potro has the advantage going into the tie breaker? He's hitting the ball far better and has lifted his game.
 
Why are Argentines so bloody good at sports? The best football player in the world (and the best football player ever, too!), one of the best tennis players clearly, and even though they don't really play the damn sport they've got one of the best rugby players. There's only 40m of them!
