Andy Roddick has overcome a big deficit to beat Ernests Gulbis of Latvia 3-6, 7-5, 6-2, 7-5 in the second round of the U.S. Open.

Roddick, the 2003 Open champion, was down by a set and trailed 5-3 in the second when he won seven consecutive games to take control of a match that began Friday night and ended after 1:30 a.m. Saturday.

Gulbis dictated play throughout and ended up with far more winners, 79 to 42, and unforced errors, 60 to 21.

But the eighth-seeded Roddick never faced a break point in the third or fourth set.
