From YT:
Roger Federer hit another tweener in his 1st round match in US Open 2010 vs. Brian Dabul - 2nd set. He looked as if he himself couldn't believe he pulled the shot again :). Very cute/sheepish smile on his face after the shot. Some suggested that this one is harder to hit than the one he hit vs. Djokovic in US Open 2009 semi final match because this time he was even further away from baseline. Watch the magician pulls yet another trick! The great Roger Federer!
