Defending champion Daniil Medvedev continued his straightforward passage through the US Open draw to set up a fourth-round clash with Nick Kyrgios.
Medvedev, who won his first grand slam title in New York 12 months ago, is yet to drop a set and was a comfortable 6-4 6-2 6-2 winner over Wu Yibing, the first Chinese man to make the third round at the US Open.
