Roddick takes revenge against Mahut

American fourth seed Andy Roddick advanced to the quarter-finals of the ATP BB&T Atlanta Open on Wednesday with a straight-sets victory over his French Open conqueror Nicolas Mahut.

Roddick, who lost to Mahut in the first round at Roland Garros earlier this year, prevailed 7-6 (7/4) 6-3 in one hour 37 minutes after rain had delayed the start of the match by almost five hours in Georgia.
