Aryna Sabalenka took a big step towards retaining her Australian Open crown by beating American fourth seed Coco Gauff 7-6(2), 6-4 in a thriller on Thursday to reach the final where she will meet Zheng Qinwen or qualifier Dayana Yastremska.
In a rematch of their US Open final in September, the two reigning hardcourt Grand Slam champions made contrasting starts as Belarusian Sabalenka fired an ace and revved up her forehand to hold before pouncing on two double faults by Gauff to break.
But what followed was an intense contest between two players hoping to forge ahead and win their second Grand Slam title, and it was Sabalenka who held firm to become the first player since Serena Williams in 2016 and 2017 to make back-to-back Melbourne finals.
"I think I was able to focus on myself," Sabalenka said. "I was thinking she's going to move really well, put all balls back to me and I had to be ready to play an extra shot.
"I was just ready for anything tonight and I think that was the key. And the support, last time I played here I didn't have almost any support."
Gauff hit back right away and the pair swapped breaks again but the 19-year-old New York champion continued to teeter on her serve, allowing Sabalenka to settle her nerves after going 6-5 down in a frantic spell to clinch the first set in a tiebreak.
The pair were locked together until 4-4 in the second set as Sabalenka countered Gauff's speed with power and the 25-year-old second seed edged ahead with a decisive break when the teenager hit a shot long before sealing victory with two massive serves.
"I really enjoy playing (Coco) she's an incredible player, win or lose it's great matches," said Sabalenka, who fell in three sets to Gauff in the Flushing Meadows final.
"I really hope in the future we're going to play many more finals. Of course, I hope I win them all," she added with a laugh.
Sabalenka will set her sights on becoming the first woman to win consecutive Australian Open titles since compatriot Victoria Azarenka in 2012 and 2013.
Zheng ends Yastremska's fairytale run
China's Zheng Qinwen ended the fairytale run of qualifier Dayana Yastremska at the Australian Open on Thursday with a 6-4 6-4 victory to reach her first Grand Slam final, where she will face defending champion Aryna Sabalenka.
The points were short and sharp for most of the battle and followed the same pattern in both sets, with the two swapping breaks early on then Zheng snaring the extra break in the seventh game both times.
In the first set, Zheng was able to keep up the pressure on Yastremska, blasting cross-court winners off both wings, and left the 23-year-old Ukrainian clutching her abdomen in pain.
After taking a medical timeout off court, Yastremska returned with Zheng holding in the next game.
The Ukrainian extended the set winning the following game with a clever drop shot, but she piled on the errors in the next game, handing Zheng the first set.
The 12th seed started off stronger in the second set, holding her first service game to love and then snatching an early break after a string of errors from Yastremska, but the Ukrainian broke straight back.
Zheng broke again in the seventh game, helped by a double fault from Yastremska and a shanked shot that flew long. Yastremska bravely held in the next game, with Zheng fluffing an easy smash, but the Chinese player snared the match with an unreturnable serve.
