Coco Gauff and Aryna Sabalenka will rekindle their rivalry in the semi-finals of the Australian Open, a rematch of the 2023 US Open final won by Gauff, after the two champions advanced on a dramatic day in Melbourne.
In a result that is testament to Gauff’s mental toughness, the 19‑year‑old found a way through despite playing poorly in the first two sets. After more than three hours in the Melbourne heat, Gauff emerged from a messy, dramatic battle to reach the semi-finals with a 7-6 (6), 6-7 (3), 6-2 win against Marta Kostyuk of Ukraine.
Sabalenka, the second seed and defending champion, returned to the semi-finals with another imperious performance as she dominated Barbora Krejcikova 6-2, 6-3 to continue her relentless run through the draw. Sabalenka’s performance came despite her and Krejcikova taking to court two hours later than planned with Gauff and then Novak Djokovic surviving lengthy battles on Rod Laver Arena.
Early in the first quarter-final it was Kostyuk who thrived, demonstrating her varied skillset with her excellent athleticism, deft touch, and ability to move forward to the net. The 21‑year‑old led 5-1 as Gauff’s unforced errors piled up. But the American forced her way back into the first set, reeling off four consecutive games before holding on in the tie-break.
“I was playing not great,” Gauff said. “I was just missing everything on both wings and not serving well. I was just trying to win one extra game. That was really the one thing. I was just, like, let me make it competitive. Obviously sometimes when you’re down 5-1 you’re not expecting to win the set. I believe every point, every game matters, and eventually the score started to get closer.”
The tables turned in the second set when Gauff led 5-3 and stood two points from victory before Kostyuk dug in, demonstrating her own grit and athleticism by recovering to force a third set against a faltering Gauff. Despite her disappointment, the US Open champion immediately recovered and produced her best tennis in the decisive set to secure victory.
Afterwards, Gauff laughed as she noted that she had never read Winning Ugly, the book authored by her coach, Brad Gilbert, despite her mother purchasing it when they considered hiring the 62-year-old. Regardless, in her young career, Gauff has proved herself extremely proficient at scraping through wins when far from her best.
She is now 34-4 (89.4%) since the start of the North American hard‑court swing at the end of July, and has won her first 10 matches of the season. With 49 victories at grand slam tournaments, the 19-year-old ties Serena Williams for the second most by an American teenager in the Open era. Only Jennifer Capriati (50) has won more.
Although she faltered, Kostyuk finished the biggest match of her career satisfied with her performance and fight, and excited for the year ahead. Earlier in the tournament, she said she believes she and her fellow Ukrainian players were successful in drawing attention to the war in Ukraine. Her compatriot Dayana Yastremska will face Linda Noskova on Wednesday for a spot in the other semi-final.
“I think [the] girls did really well,” Kostyuk said. “I hope we will be able to succeed on most of the tournaments, especially the big ones where there is a lot of media. I think people should be reminded.
“I was texting with some people from Kyiv [before the match]. I said: ‘How is it? How are you guys?’ They said: ‘Well, we were looking between your score and where the missiles are flying.’ So [the war is] still there. It’s still there.”
Like Gauff, the past year has been the making of Sabalenka, who has achieved remarkable consistency at the grand slam tournaments. She has continued to perform at an incredible level early this year; not only is she yet to drop a set in Melbourne, but no opponent has won four games in a set against her.
Krejcikova, the 2021 French Open champion, stepped on to Rod Laver Arena with the tools to make life difficult for the 2023 champion. Instead, she was bulldozed by Sabalenka, who produced another spectacular exhibition of controlled, disciplined aggression. Sabalenka is just the third female player in the 21st century to reach six semi-finals in a row after Serena Williams, who did so twice, and Capriati.
“I think my mindset is that I’m not getting crazy on court, I’m not rushing things,” Sabalenka said as she explained her semi-final sequence. “I’m just playing point by point, and that’s it, and fighting for every point without overthinking about my dreams, about what I want to do, about how many slams I want to win and all that stuff.”
There is no doubt the 25-year-old has performed at the highest level of all the players left in the women’s draw but Gauff showed in New York that her supreme defence can neutralise Sabalenka’s imperious attack. On Thursday, they will meet again.
