Amazing the number of tennis "experts" that appear during Wimbledon.
Roddick has been in poor form recently plus he's had an injury. Roddick only converted 1 out of 12 (yes 12!) break points against Murray. The match was a lot closer than the score suggested. And if you know anything about tennis at all you'll see from the match that Roddick was nowhere near his best. He was trying to play at the net when he should've done what he does best and stay at the baseline and worn Murray down. Instead he kept rushing to the net on some terrible approach shots, which allowed Murray to simply put the ball past him without any pressure.
You really have no clue about tennis do you? The head to head between Henman and Federer is 6-4 in Henman's favour.
Did you watch the 2003 Paris Masters? Henman beat Federer and then beat Roddick the following day, both in straight sets. You just happened to miss that headline I suppose. But then you only follow tennis for 2 weeks of the year...
