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)."
