In the end, it appeared that Roddick had thought this match would be a near-walkover. Consequently, he didn't look too familiar with Muller's game, and looked very uncomfortable against a lefty. It was a good match and a great upset.
On the ladies' side, I saw the end of Davenport's win over Li Na. True, Lindsay won in straight sets, but she was really slow to close the door, dropping several match points on the way. She won't get past Dementieva or Patty Schnyder playing that way, and that's just the competition in her bracket.
