Germany's World No. 4 Alexander Zverev won his 16th consecutive match of the year as he stormed into the semi-finals of the US Open, beating Lloyd Harris of South Africa in straight sets on Wednesday. The fourth seed, who is on a winning streak since the start of the Tokyo Olympics in July, raced past Harris, 7-6(6), 6-3, 6-4 at the Flushing Meadows here. Zverev hit 43 winners and broke service four times to make back-to-back semis in New York.

"He was serving incredible, in the first set especially. I mean, I didn't have a lot of chances on his serve and somehow managed to win that first set, loosened me up a little bit and started playing a lot better," Zverev, the Tokyo Olympics and Cincinnati champion, said after the match. "In the third set, he started swinging. He started playing incredible tennis. Yeah, I'm happy to be through in three (sets)."
