2:6 6:4 6:1 against Stepanek, seems like he had a good comeback after dropping the first set. Now against Djokovic, nothing to lose for Tommy. That's his first quarterfinal in a Masters event since Indian Wells 08.
Haas also got a place in the Cincinnati draw now. From now on, direct entry into all tournaments will be out of question anyway. A lot of tennis to play, but he seems so fit, it shouldn't be a big problem, as there is at least a week of rest before the US Open start.
