This was a classic Roddick match. Berdych just served big and in the end snuck out a break on his opponent's errors. Dolgo really abused Berdych off the ground for the majority of this match.
True, Dolgo was really strolling through and doing major damage for most of the match with his accuracy, his ability to hit flat and hard and hit behind Tomas and expose his movement. But playing the way Dolgo does will naturally end up with him making a lot of errors, and it cost him. It's why Tomas now and Andy for so long have been in the top 10.
