Another Heartening Victory for Federer

Remember when Guga Kuerten won the French Open and drew a heart in the clay? Sometimes it really is all about heart, particularly when it comes to tiebreaks.
The score in last night's quarterfinal match at the U.S. Open between Roger Federer and Andy Roddick suggested that not much separates the two: 7-6, 7-6, 6-2. Not much except the great heart and love for tennis reflected in Federer's 14-1 lifetime record against Roddick and 11 Grand Slam titles (possibly soon 12) versus Roddick's one. If their head-to-head record were flipped, so too might the number of Grand Slam trophies in their trophy cases.
It shouldn't be surprising that Roddick gets to a tiebreaker against Federer, given Roddick's serve. What is surprising, despite Federer's brilliance, is that Roddick didn't win either tiebreak, given his serve.
Which must have abandoned Roddick to a certain extent. Tiebreaks are all about heart, nerve and cool, and Federer showed once again that he has those in spades.
As for Roddick--6-2 in the third? That score is the very embodiment of someone who is disheartened.
