Top-ranked Daniil Medvedev ended the historic run of Yibing Wu with a 6-4, 6-2, 6-2 victory in the third round on Friday at the US Open in New York.
The defending champion moves on to face Wimbledon runner-up Nick Kyrgios on Sunday. Medvedev is bidding to become the first repeat champion in Flushing Meadows since Roger Federer won five in a row from 2004 to 2008.
Medvedev had 12 aces to only one for the 22-year-old Wu, who was the first Chinese man to reach the third round of the US Open.
"I felt like it was a high level match because he played great," Medvedev said after the match. "[His] returns were just unbelievable, like when he's on the ball was one of the best I ever saw."
Medvedev added that he feels "pretty happy with my level."
"Some long rallies, not [many] unforced errors," he said. "[I] finally managed to beat a strong opponent, I'm really happy."
Kyrgios, the No. 23 seed, swept past American J.J. Wolf 6-4, 6-2, 6-3.
