Sabalenka, who fell to Rybakina in the Australian Open final  before turning the tables on the Kazakh in the Indian Wells title match this earlier this month, broke the big-serving Rybakina twice in each set to come out on top in the blockbuster semi-final and keep her bid for the "Sunshine Double" of Indian Wells and Miami on track.

"I think I did everything right," said Sabalenka, who applied ruthless pressure on Rybakina's serve while delivering a sterling service performance that featured nine aces -- including four in a row across the seventh and ninth games of the opening set.

"She's an incredible player, always pushes me to the limit," Sabalenka said. "With her, you have to bring your best tennis and that's why I was able to pull out such great tennis today."

Sabalenka had to save a match point to beat Rybakina in Indian Wells, but she was on the front foot on Thursday, seizing a break for a 3-1 lead in the opening set.

Rybakina recouped the break immediately, but Sabalenka broke again to pocket the set and took command in the second with a break for 2-0 in a game which Rybakina led 40-0.

Trailing 0-4, Rybakina clawed back a break for 4-1 but Sabalenka wouldn't flinch again. Rybakina saved one match point on her own serve before Sabalenka served it out with a love game punctuated by a fierce forehand winner.

The match marked the first time outside the WTA Finals that the world's two top-ranked players met before a final since Martina Hingis and Jana Novotna in the 1998 US Open semi-finals.

It could only come about because Rybakina was seeded third, her rise to second in the rankings on Monday coming a day after the Miami draw was made.
