NEW YORK (AP) -- Sixth-seeded Tomas Berdych was pushed to five sets before moving on to the third round of the U.S. Open.
Berdych beat 65th-ranked Martin Klizan of Slovakia 6-3, 4-6, 6-2, 3-6, 6-3 in 3 hours, 45 minutes Friday.
Klizan double-faulted on break point to give Berdych a 3-1 lead in the final set. Berdych then saved a break point in the next game with a big serve.
He fought off two more break points in the last game to serve out the match. Klizan had 66 unforced errors.
Berdych reached the semifinals at the U.S. Open two years ago. Klizan made the fourth round that year, upsetting Jo-Wilfried Tsonga along the way.
