Aryna Sabalenka extended her unbeaten run at the Wuhan Open to 20 matches with a straight-sets victory over Elena Rybakina on Friday.

The world No 1 beat Rybakina 6-3 6-3 to keep her hopes alive for a fourth straight title and set up a semi-final match with America's Jessica Pegula.

It is Sabalenka's 11th semi-final of the year out of the 15 tournaments she has played in, as she broke Rybakina in the eighth game with a forehand winner.

Sabalenka clinched the opening set with a hold and broke Rybakina's serve in the first game of the next set to continue putting pressure on her opponent.

The top seed struggled with a few service games later on, but still managed to close out the victory and improved her win-loss record against Rybakina to 8-5.

Sabalenka won the Wuhan title in 2018, 2019, and 2024 after the tournament made a return following the Covid-19 pandemic.

Pegula came from behind to beat Czech Katerina Siniakova 2-6 6-0 6-3 for her 50th match win of the season as she aims to qualify for the season-ending WTA Finals next month.

Sabalenka has won eight of her 10 meetings with Pegula, including in the US Open final last year.

American third seed Coco Gauff meets German Laura Siegemund in another quarter-final later on Friday, whilst second seed Iga Swiatek comes up against seventh seed Jasmine Paolini in a rematch of their 2024 French Open final.
