Djokovic into China Open final

The Australian had advanced over Hubert Hurkacz after the 29-year-old from Poland retired from their semi-final with an adductor muscle strain. Medvedev's disqualification arose from a moment deep in the match.

When he failed to return a point, the ball bounced off the back wall and Medvedev hit it with a backhand up into the stands, with the chair umpire stopping play. "Terribly sorry to the spectator, first of all," he, adding it was "100 percent an accident" and that he wished to apologise to the fan in person.

"The ball was bouncing back, so I tried to, like, just hit it anywhere, so it doesn't go out from the court," he said. It had been a physical battle before Medvedev's disqualification. Djokovic was red-faced and hunched over between points, with both players forcing each other through gruelling rallies, until the Serbian took control in the second set.

The 39-year-old put on a dazzling performance and saved 16 break points across the match, diving at the baseline and sprinting to the net. "I didn't see what happened, to be honest," Djokovic fan was hit.

"I'm sure that Daniil didn't... do it intentionally. It happened by accident. Sorry for the crowd," he said, adding that it had been a tough contest.

"I know the feeling," Djokovic, recounting his own disqualification from the 2020 US Open after accidentally hitting a ball at a line judge. "It's horrible... but it happens," he said. Although Djokovic was three points away from winning the match, he said victory wouldn't have come easy and that he got "lucky" in a "very exhausting" battle.

'Gave everything'In the women's draw, third-seeded Coco Gauff dispatched Chinese teenager Sun Xinran 7-5, 6-1 to secure a meeting with Belgium's Elise Mertens in the round of 16. "Today was really just about feeling," said the 22-year-old American, adding that it could be tough to play young players with styles largely unknown.

"I was just trying not to get frustrated out there," Gauff added, with a loud crowd behind the 16-year-old. Former world number one Iga Swiatek staged a comeback to advance, dominating a must-win tie-break to beat Croatia's Donna Vekic 4-6, 7-6 (7/0), 6-2.

"I was just angry, wanted to change something, because clearly it wasn't working," the 25-year-old from Poland said on court. "Sometimes if you care a bit less because you're... probably going to lose, it also helps you a bit," she.

She will face American teenager Iva Jovic for a spot in the quarter-finals. China's Zheng Qinwen was tested by Marie Bouzkova, enduring her third three-setter of the tournament to beat the Czech player 7-6 (7/3), 4-6, 7-5.

She pulled out some of her most accurate tennis to clinch the last two games and win when 27th-ranked Bouzkova fired long. "I gave everything," said Zheng, who had already spent more than five hours on court in the first two rounds.

"Truthfully speaking, I felt a lot of pressure today," the 23-year-old, thanking fans for their support. Zheng, the current world number 54, next plays 118th-ranked Alina Charaeva, who sent out top seed Elena Rybakina in the second round.

Wimbledon champion Linda Noskova also advanced and will face Ekaterina Alexandrova in the last 16, while Ukraine's Elina Svitolina will play American Ann Li.
