Aryna Sabalenka did not make many mistakes – well, until near the end – despite not sacrificing any power, and outplayed Amanda Anisimova for a 6-3, 7-6 (3) victory in the U.S. Open final Saturday, making her the first woman to win the tournament in consecutive years since Serena Williams more than a decade ago.

The No. 1-ranked Sabalenka picked up the fourth Grand Slam title of her career, all on hard courts. This was not all smooth sailing, though.

Sabalenka twice led by a break in the second set, and served for the win at 5-4. But at 30-all, so close to the trophy, she had a chance to hit an overhead and get to match point. Instead, while backpedaling, Sabalenka put the ball into the net, giving Anisimova a break chance.

After that excruciating miss, Sabalenka dropped her racket on the blue court and smiled a rueful smile. A moment later, Anisimova – a 24-year-old American – converted the break to get to 5-all and shook her left fist while 24,000 or so of her closest friends in Arthur Ashe Stadium rose to applaud and shout.

However, 15 minutes after the flub, Sabalenka was kneeling on the court and covering her face with both hands, coming through on her third match point – which made perfect sense, because she simply doesn't lose tiebreakers. This one made her 21-1 in those this year, winning her last 19.

Not since Williams took three straight titles from 2012-2014 had a woman repeated as the champ in New York.

The result also meant Sabalenka avoided becoming the first woman to lose three major finals in a single season since Justine Henin in 2006.

"All those tough lessons (were) worth this one," Sabalenka said. "I'm speechless right now."

Sabalenka, a 27-year-old from Belarus, was the runner-up to Madison Keys at the Australian Open in January and to Coco Gauff at the French Open. Then, at Wimbledon in July, Sabalenka was eliminated by Anisimova.

In the women's singles wheelchair final, China's Li Xiaohui couldn't build on a 6-0 first set win and ended up losing to Japanese player Yui Kamiji in the end.

Li was flawless in the opening frame and clinched it without reply in just half an hour. World No. 1 Kamiji went back to the locker room and returned looking like a different player.

The Japanese has already won this year's Australian Open and French Open, and came runner-up at Wimbledon. She continued to show her Grand Slam pedigree and claimed the second set 6-1.

Kamiji stayed composed in the decider and kept pressing Li before closing out the set 6-3, to seal her third singles title in New York and 11th major overall.
