But if I want to go further in this tournament I've got to do better on break points," On his below-par performance, Roddick quoted "That was really ordinary. The one I ended up getting was because he doubled." He further added that "I'm doing a good job of getting break points. I feel like I'm in every opponent's service game, but I can't miss second-serve returns at 15-30 or 30-all. I'm very close to playing really well. It's just a matter of tightening things up to make that happen."
