NEW YORK, Sept. 9 (Xinhua) -- Germany's Alexander Zverev defeated South African Lloyd Harris 7-6, 6-3, 6-4 to advance to the men's singles semifinals in the U.S. Open here on Wednesday.
The world No. 4 experienced a tough start before dominating the rest of the game.

"In the third set, he started swinging. He started playing incredible tennis. I'm happy to be through in three," added Zverev.
