Alcaraz, Sabalenka sail through at China Open

Top seeds Carlos Alcaraz and Aryna Sabalenka both breezed into the next round of the China Open with routine victories on Sunday.

Alcaraz sealed a place in the men's quarter-finals with a smooth 6-2, 6-2 victory over Italy's Lorenzo Musetti in Beijing.

The world number two overpowered his opponent and seized the first set when Musetti whacked a baseline backhand into the net.

The Spaniard then broke serve twice in the second set and saw out a comfortable match with an unreturned serve.

He will next face Casper Ruud after the world number nine came back to beat Argentina's Tomas Etcheverry 1-6, 7-5, 7-6 (9-7).

"I feel great, honestly. It was a good performance against a really tough opponent," Alcaraz said at a post-match news briefing.

"(My level) didn't (go) up and down. I stayed at a high level, high quality, during the whole match," the 20-year-old said.

The match balls have been a sticking point in the tournament's early rounds, with Alcaraz's main challenger Daniil Medvedev describing them on Saturday as "like a grapefruit".

Alcaraz said he had also felt the distinct quality of the balls, which Medvedev said were also quick to fluff up, "since day one".

"It's something tough, but tennis players have to get used to the balls in every tournament," he said in response to a question from AFP.

"Here, in just one or two games, the balls become really different from (when they're) new. It's a kind of different (style of) play," he said.

Also on Sunday, world number seven Jannik Sinner obliterated Japan's Yoshihito Nishioka 6-2, 6-0.
