Iga Swiatek, fresh off tourney win in South Korea, wins 400th career match at China Open

Wimbledon champion Iga Swiatek defeated Camila Osorio for her 400th career win and advanced to the fourth round at the China Open in Beijing on Monday.

Swiatek, the first player to register 25 or more wins at WTA-1000 events for three consecutive seasons, showed no signs of slowing down as she dismantled her Colombian opponent 6-0 in the first set before Osorio retired in the opening game of the second set.

"I'm sorry for Camila because she's always giving 100 per cent," Swiatek said. "But overall, like besides that, I feel like I played good in the first set and really used my game to push Camila."

Top-seeded Swiatek, who won last week's Korea Open in Seoul, next plays American Emma Navarro. Navarro was leading Lois Boisson 6-2, 1-0 when the French player retired from their match.

Fifth-seeded Jessica Pegula saved three match points before knocking out Emma Raducanu 3-6, 7-6 (9), 6-0. Pegula improved her record against the Briton to 3-1.

In other third-round matches, fourth-seeded Mirra Andreeva beat Jessica Bouzas Maneiro 6-4, 6-1 and Marta Kostyuk beat Aliaksandra Sasnovich 6-4, 6-2.

On Sunday, Coco Gauff of the United States was forced to go the distance against Canada's Leylah Fernandez before closing out a tight three-setter 6-4, 4-6, 7-5 to advance to the third round.

In the men's tournament, top-seeded Jannik Sinner cruised into the semifinals after defeating Fabian Marozsan 6-1, 7-5.

The Italian next plays third-seeded Alex de Minaur, who advanced by walkover after his opponent Jakub Mensik retired injured while trailing 4-1 in the first set.

Daniil Medvedev defeated second-seeded Alexander Zverev 6-3, 6-3 and reached his 60th career semifinal, and first since June. Medvedev's second win this year against Zverev
