Atlanta, USA, 28 July 2021 | Leigh Rogers

Nick Kyrgios has defeated two-time Grand Slam finalist Kevin Anderson to advance to the second round at an ATP 250 tournament in Atlanta.

Making his first singles appearance since an abdominal injury derailed his Wimbledon campaign, the 26-year-old Australian served up 15 aces in a 7-6(4) 6-3 victory.

Kyrgios, who had lost his two previous matches against the world No.75-ranked South African, did not face a break point in the 81-minute match.

The Atlanta Open 2016 champion joins fellow Australians Jordan Thompson and Chris O’Connell in the second round.

O’Connell eliminated American Denis Kudla in first-round action earlier today, with the world No.132 recording his fourth career main draw win at tour-level.
