The world number one from Belarus, fresh off her first triumph in the California desert, became the fifth woman -- and the first since Iga Swiatek in 2022 -- to win both of the elite early season hardcourt WTA 1000 titles.

"It means a lot," Sabalenka said after joining Poland's Swiatek, German great Steffi Graf, Belgian Kim Clijsters and fellow Belarusian Victoria Azarenka on the list of women to win both titles in the same year.

"My goal always been to put my name in the history, and I just did it."

Sabalenka underscored her WTA dominance in a season in which her only defeat to date was her Australian Open finals loss to Elena Rybakina -- who she went on to beat in the Indian Wells title match and in the semi-finals here.

She handed Gauff her first career defeat in a hardcourt final.

The American had won her first nine, including a triumph over Sabalenka in the 2023 US Open championship match.

Gauff had also beaten the Belarusian for the title on the red clay of Roland Garros last year.

So Sabalenka said she wasn't surprised to see Gauff dig in, even after the Belarusian pocketed the first set with a ruthless display of power and precision.

She broke Gauff to open the match and, after Gauff saved three break points in a gritty fifth game, broke the American again in the seventh before serving it out in 37 minutes without facing a break point herself.

In a tense second set, Gauff's first break point chance -- from a blistering backhand passing winner in the second game -- sparked a jubilant reaction from the crowd at Hard Rock Stadium, home of the NFL's Miami Dolphins that is just about an hour away from Gauff's Delray Beach home.

But Gauff couldn't convert, slamming a forehand into the net on the next point as Sabalenka held.

It needed another gutsy hold from Gauff to keep it on serve in the fifth game.

Up 40-0, she wasted three game points with a pair of errors off the ground and a double fault then had to save a break point before taking the game.

But Gauff was finding more depth on her returns and broke Sabalenka for the first time to take the second set.

"I knew that she's going to try her very best to fight in this match," Sabalenka said.

"I was just trying to keep a positive mindset going into the third set. I'm super happy how well I handled my emotions how well I stayed focused from the very beginning to the very end."

- What a month -

And the third set, again, was virtually all Sabalenka.

She broke to open the final frame and broke again when Gauff sailed a backhand long on Sabalenka's first match point.

"What a month," said Sabalenka, who along with two prestigious titles acquired a new puppy and got engaged to boyfriend Georgios Frangulis.

Gauff was also feeling grateful after a rocky March that saw her withdraw from her third-round match at Indian Wells with a nerve issue that caused "scary" pain in her left arm.

She had said after a dominant semi-final win over Karolina Muchova that she was making progress with the inconsistencies in her serve and forehand, although seven double faults hurt her cause against Sabalenka.

And after considering skipping the event, the 22-year-old was thrilled to reach the final for the first time.

"I feel like I'm nowhere near my peak of my tennis, so I think it gives me comfort a little bit playing these tournaments and having great results," she said.
