NEW YORK — As good as she has been this year, Iga Swiatek came to the U.S. Open unsure of what to expect.
She complained that women use different, slightly lighter, tennis balls than the men at Flushing Meadows, where she’d never been past the fourth round. She was trying to grow accustomed to the noise and distractions, the hustle and bustle, of the Big Apple. And she arrived with a record of only 4-4 since her 37-match winning streak ended in July.
None of that matters now. Cementing her status as her sport’s new dominant figure by winning what is expected to be the last tournament of Serena Williams’ career, the No. 1-ranked Swiatek outplayed No. 5 Ons Jabeur 6-2, 7-6 (5) at Arthur Ashe Stadium on Saturday to claim her first U.S. Open and third Grand Slam title overall.
“Just not expecting a lot, especially before this tournament,’’ said Swiatek, who is 55-7 in tour-level matches with seven trophies in 2022, both best in the WTA. ‘‘It was such a challenging time, you know?
“For sure, this tournament was really challenging, also, because it’s New York. It’s so loud. It’s so crazy. I’m really proud that I could handle it mentally.”
Swiatek, like Jabeur, travels with a sports psychologist, and it took some fortitude to finish this one off. At 6-5 in the second set, Swiatek held her first championship point. Right before Jabeur served, Swiatek jogged over to the sideline to change rackets — an unusual choice at that moment.
When action resumed, Swiatek missed a backhand. That could have been tough to recover from. Indeed, Jabeur pushed things to the tiebreaker, which she then led 5-4. But Swiatek steeled herself, took the last three points and soon was accepting the silver trophy and a $2.6 million winner’s check, joking: “I’m really glad that is not in cash.”
The 21-year-old from Poland won the French Open in June for the second time and is the first woman since Angelique Kerber in 2016 to win two major titles in a season.
“I really tried, but Iga didn’t make it easy for me; she deserved to win today,” said Jabeur, a 28-year-old from Tunisia who will rise to No. 2 in the rankings Monday.
Smiling while looking at Swiatek, Jabeur told a crowd that offered her plenty of support: “I don’t like her very much right now, but it’s OK.”
Jabeur is the first African woman and first Arab woman to reach a Grand Slam final and was participating in her second straight. But she is 0-2 at that stage, including a runner-up showing at Wimbledon in July.
‘‘I’m going to keep working hard, and I know we’ll get that title someday soon,” Jabeur said to her fans and members of her support team, who wore black shirts with white writing that read, “Yalla Habibi,” Arabic for “Let’s go, my love!”
It didn’t help on this sunny, 85-degree afternoon that Jabeur needed to deal with Swiatek, who has won her last 10 finals in straight sets and was great from the get-go.
Jabeur did not face a break point in her semifinal victory, but she got broken right away when Swiatek laced a cross-court backhand winner off a short ball to cap a 15-stroke exchange.
Eight minutes in, Swiatek had grabbed 12 of the first 14 points for a 3-0 edge.
Using her heavy topspin forehand to take charge from the baseline, Swiatek dictated the tempo and trajectory of points. She ran her opponent this way and that, never letting Jabeur use the sorts of spins and variety that she’s accustomed to.
When Jabeur did show off some of what she can do, Swiatek would manage, more often than not, to elongate points. She used her strong court coverage, backed by a soundtrack of squeaky sneakers as she darted everywhere, sometimes even sliding as she arrived at a ball, the way one does on red clay, her favorite surface.
When Jabeur missed a slice forehand early in the second set, she dropped her racket to reflect her despair. A few points later, she flung her racket while off balance and falling face down. A running, down-the-line backhand passing shot from Swiatek on the next point made it 2-0 in that set. Swiatek raised a clenched fist and yelled, “Come on!”
Then Jabeur did make things interesting, but only briefly. She got to 4-all, and after ending up on her back when an off-balance backhand won a point in the next game, she stayed there, enjoying the moment, pumping her fists while on the ground.
Jabeur earned three break chances in that game, any one of which would have allowed her to serve for the set. She could not cash in there, though, missing a groundstroke on each.
