When Madison Keys stepped into Rod Laver Arena at 7:37 p.m. on Saturday night ahead of the Australian Open final, she strode right past the Daphne Akhurst Memorial Cup, the silver trophy that goes to the women’s champion and was placed on a pedestal near the entrance to the court.

Keys didn’t break stride. Didn’t stop to stare. That bit of hardware was then moved near the net for the pre-match coin toss, close as can be to where the American stood. Close enough to touch. Close enough to feel real. Also right there was Aryna Sabalenka, the No. 1-ranked woman and two-time defending champion at Melbourne Park, who would not make things easy on this cool, breezy evening.

Two-and-a-half hours — and one 6-3, 2-6, 7-5 victory over Sabalenka — later, there was Keys, smiling the widest smile while holding that bit of hardware with both hands, a Grand Slam champion for the first time at age 29.

This was Keys’ second chance to play for a major title: The first ended in a lopsided loss at the 2017 U.S. Open, an experience that taught her she had to play through nerves.

“I have wanted this for so long,” said Keys, who was born in Illinois and now is based in Florida, “and I have been in one other Grand Slam final, and it didn’t go my way, and I didn’t know if I was going to get back in this position.”

She is the oldest woman to become a first-time Slam champ since Flavia Pennetta was 33 at the 2015 U.S. Open. This was the 46th Slam appearance for Keys, the third most before winning a major title, behind only Pennetta’s 49 and Marion Bartoli’s 47 when she won Wimbledon in 2013.

Keys did not take an easy path, either.

Before this three-set victory came one against No. 2 Iga Swiatek in the semifinals, saving a match point along the way. Not since Serena Williams in 2005 had a player defeated both of the WTA’s top two women at Melbourne Park.

“Madison: Wow, what a tournament,” Sabalenka said during the on-court ceremony, in which she also joked with her entourage that the defeat was their fault.

“Enjoy the celebration,” she told Keys. “Enjoy the really fun part.”

Keys, ranked 14th and seeded 19th, prevented Sabalenka from earning what would have been her third women’s trophy in a row at the Australian Open — something last accomplished by Martina Hingis from 1997-99 — and her fourth major title overall.

When it ended, Keys covered her face with her hands, then raised her arms. Soon, she was hugging her husband, Bjorn Fratangelo — who has been her coach since 2023 — and other members of her team, before sitting on her sideline bench and laughing.

Sabalenka chucked her racket afterward, then covered her head with a white towel.

“Just wasn’t my day,” Sabalenka said.

Keys broke three times in the first set, helped in part by Sabalenka’s four double-faults and 13 total unforced errors.

Don’t for a moment think this was merely an instance of Sabalenka being her own undoing.

Keys certainly had a lot to do with the way things were going, too. She compiled an 11-4 edge in winners in the opening set, managing to out-hit the big-hitting Sabalenka repeatedly.

For a stretch, it seemed as though every shot off the strings of Keys’ racket — the one she switched to ahead of this season, at Fratangelo’s urging, to protect her oft-injured right shoulder and to make it easier to control her considerable power — was landing precisely where she wanted.

Near a corner. On a line. Out of the reach of Sabalenka, a 26-year-old from Belarus.

Also important was the way Keys, whose left thigh was taped for the match, covered every part of the court, racing to get to balls and send them back over the net with intent. On one terrific defensive sequence, she sprinted for a forehand that drew a forehand into the net from Sabalenka, capping a break for a 4-1 lead.

Never one to hide her emotions during a match, Sabalenka frequently displayed frustration while trailing on the scoreboard, kicking a ball after netting a volley, dropping her racket after missing an overhead, slapping her leg after an errant forehand.

Sabalenka took a trip to the locker room before the second set, and whether that helped clear her head or slowed Keys’ momentum — or both — the final’s complexion soon changed. Keys’ first-serve percentage dipped from 86% in the first set to 59% in the second. Sabalenka raised her winner total to 13 in the second set and began accumulating, and converting, break points.

When she sent a backhand down the line to force an error by Keys for a break and a 2-1 lead in the second, Sabalenka shook her left fist and gritted her teeth as she walked to the sideline.

The action in the third set was tight and tense, without so much as a single break point until its final game, when Keys came through with one last forehand winner.

Here’s how close this was: Keys won just one more point than Sabalenka, 92-91. Both finished with 29 winners.

Keys had to wait, yes, but the moment she yearned for had arrived.
