Second seed Daniil Medvedev overcame a mid-match wobble to beat Ugo Humbert 6-4, 3-6, 6-1 on Monday and move into the China Open semi-finals, where he will face Alexander Zverev in their fifth meeting this season.

Chengdu champion Zverev, who is rediscovering his best form after a serious ankle injury last year, extended his winning run to seven matches with a 6-1, 6-7 (5-7), 6-3 win over Chile’s Nicolas Jarry.

The 10th-ranked German has lost three times to Medvedev this year but flipped the script in their last meeting in Cincinnati.

“It seems like we have to play each other every tournament this year. It’s the fifth time we’re going to play each other,” Zverev said. “Every time we play, it’s a battle.

“I’m looking forward to what’s to come. He’s playing great tennis. I hope I can bring my A game.”

Top seed Carlos Alcaraz takes on Casper Ruud while Grigor Dimitrov meets Jannik Sinner in the other two quarter-finals.

In the women’s tournament, world No.2 Iga Swiatek powered into the second round on her Beijing debut with a 6-4, 6-3 victory over Spain’s Sara Sorribes Tormo.

US Open winner Coco Gauff roared to victory in her first match as a grand slam champion, as the American downed Ekaterina Alexandrova 7-5, 6-3.

World No.7 Ons Jabeur eased past Ashlyn Krueger 6-3, 6-4.
