Andy Murray got the 2009 WTF off to a rousing start in his home country's largest city Sunday, outlasting Juan Martin del Potro over three sets to get the first win of the round robin by the score of 6-3, 3-6, 6-2.

With the crowd on his side and the slow, hard courts in the O2 arena being exactly to his liking, its tough to see anyone but Murray winning this group.

Roger Federer had a decidedly tougher go of it early on in his first match against Fernando Verdasco.  Federer wasn't being anywhere near aggressive enough in the rallies, and the always aggressive Verdasco took full advantage, going up an early break and holding on to take the first set 6-4.

It really seemed like a matter of when, not if, Verdasco would collapse.  And when he did, in the twelfth game of the second set, he did so in spectacular fashion.  Especially choke-licious was an overhead he hit from the baseline that bounced before hitting the chair umpire's chair.

Federer made short work of the third set, racing out to a 5-0 lead before sealing the match 4-6, 7-5, 6-1.  Verdasco looked thoroughly demoralized by the end of the ordeal, and I can't say I much like his chances against either Murray or del Potro.
