Del Potro: Future Number One. But how soon?

With his recent win over Fed proving that his US Open Final victory over the same opponent was no fluke, Del Potro has put the writing on the wall. This guy is headed to the top. With a bullet.
He's like some kind of hybrid creation. A Karlovic like serve with powerful groundies like Gonzalez and courtspeed to rival Nadal at his best. This is a rare combination and seems impossible to stop. Even for the master Federer who seems to get brutalized by the power of Del Potro's game. Watching them play you almost feel sorry for Federer who seems like a helpless bystander in the wake of Del Potro's huge game. The Argentine's only recent losses before the ATP finals had been to lowly opponents which hinted at a possible dip in motivation.


Mentally he is superior to anyone in the top ten with the possible exception of Nadal. (Who could forget the way he came from a double break down in the 3rd set to down Nadal earlier in the year?)
A fit and firing Del Potro which we are now seeing at last at the Masters Finals could be a bit like Pamela: more than a handful for any man.

Yes, the writing's on the wall: you are looking at the next world number one. The only question is how soon?
