Coco Gauff rallied Saturday from a set down for the third consecutive match as she beat Paula Badosa 4-6, 6-4, 6-2 to advance to the final of the China Open.

The sixth-ranked Gauff will play Karolina Muchova of the Czech Republic in Sunday’s final as the 20-year-old American bids for her second WTA-1000 level title.

Muchova defeated Olympic gold medalist Zheng Qinwen 6-3, 6-4 in the other semifinal.

Gauff, who has a 7-1 record in tour finals, has made a habit of slow starts in Beijing this week and the script played out again as the No. 19-ranked Badosa took a tight opening set in 59 minutes, saving 10 of 11 break points.

The Spaniard then built a 3-1 lead in the second set before the 2023 U.S. Open champion shifted the momentum by saving four break points and then breaking back to level at 4-4.

Gauff then held for 5-4 and broke Badosa again to force a deciding set.

“I felt like I was playing the right way the whole time, just a couple of unforced errors, she was playing well too,” Gauff said in her on-court interview. “I was trying to stay focused. Mentally, I just tried to reset. I got down a couple of times, and I tried to bounce back.”

With all the momentum, Gauff then broke Badosa three more times — for the loss of one of her own — as she clinched the match in 2 hours, 20 minutes.

Gauff had also lost the first set to Naomi Osaka in the fourth round before winning by walkover as the four-time major winner retired with a back injury at one set-all.

“I’ve had tough opponents the whole tournament,” Gauff said.

In the quarterfinals, Gauff trailed the No. 115-ranked Yuliia Starodubtseva before rallying to win in three.

Shanghai masters

Carlos Alcaraz and top-ranked Jannik Sinner showed no signs of fatigue from their China Open final earlier this week to advance with comfortable straight-set victories in their opening matches.

The second-ranked Alcaraz, who beat the Italian in Beijing on Wednesday for his fourth title of the year, recorded his 10th consecutive win with a 6-2, 6-2 result against 19-year-old Shang Juncheng of China.

The 21-year-old Spaniard won the first nine points of the match and four of seven break points as he rushed into a third-round meeting with another Chinese player, Wu Yibing.

“I’m not used to playing against players younger than me,” Alcaraz said. “He has been playing good tennis lately, lifting his first ATP (title in Chengdu), so I’m pretty sure he’s going to climb the rankings. I’m just happy to be able to win these kinds of matches.”

Sinner, who is dealing with an ongoing doping case, had a comfortable 6-1, 6-4 outing against Taro Daniel of Japan for his 250th career win.

The Italian, who won the U.S Open last month for his second major of the year, fired 12 aces and 38 winners.

“I felt quite comfortable today,” said the 23-year-old Sinner, who next plays Tomas Martin Etcheverry of Argentina. “I feel in good shape also physically, which is very important for me. Of course I will try to improve for tomorrow’s performance, but today I was serving really, really well, especially in important moments, and was moving well.”

No. 65-ranked Jakub Mensik of the Czech Republic broke sixth-ranked Andrey Rublev seven times on his way to an upset 6-7 (7), 6-4, 6-3 victory.

Yosuke Watanuki also had a surprise win, beating Number 35-ranked Brendan Nakashima 7-6 (4), 6-3. The Japanese qualifier plays either seventh-ranked Taylor Fritz of the U.S. or French qualifier Terence Atmane next.

Also, 24th-ranked Alexei Popyrin of Australia beat Miomir Kecmanovic of Serbia 6-3, 6-2.

Later Saturday, third-ranked Alexander Zverev began his campaign against Italian qualifier Mattia Bellucci, while fourth-ranked Novak Djokovic faced Alex Michelsen of the United States.
