Women's singles R2: Iga Swiatek [1] beat Danielle Collins 6-4 3-6 6-4
This was the first indication that Swiatek was not quite at her best in this tournament.
Collins, a former finalist here, made life tough with some brutal hitting, crushing backhands and generally rushing Swiatek into mistakes.
The Pole looked genuinely flustered as she went down 4-1 in the final set and her only hope was that Collins would blink with the finish line in sight.
And she did, her serve faltering at the crucial moment, allowing the top seed to gather herself and then reel off five straight games for victory.
“I was in the airport already,” Swiatek said. “I wanted to fight till the end. I knew that she played perfectly and it would be hard for anybody to keep that level so I wanted to be ready when more mistakes are going to come from the other side.”
Women's singles R2: Anna Blinkova beat Elena Rybakina [3] 6-4 4-6 7-6 (20)
Third seed Rybakina had looked great in the build-up and was considered by many to be the biggest threat to Sabalenka’s title defence. But the Kazakh found herself in a dogfight with Blinkova, who had never been beyond the second round in Melbourne before.
The pair went toe to toe for two hours, 46 minutes in all but it was the final-set tiebreak that made history.
Lasting 32 minutes, it was the longest deciding match tiebreak in terms of points, with 42, and in the end it was Blinkova who won it 22-20, clinching victory on her 10th match point, having saved six of her own.
"This day I will remember for the rest of my life," world No.57 Blinkova said. "Especially on this court, with this crowd. I will never forget it. It’s the best day of my life so far."
Women's singles SF: Aryna Sabalenka [2] beat Coco Gauff [4] 7-6(2) 6-4
This was a match everyone had been looking forward to since the draw was made, a repeat of the US Open final won by Gauff last September.
The American’s athleticism was a good match for the defending champion’s huge ball-striking but it was Sabalenka who started better, racing to a 5-2 lead.
Gauff had the support of the Melbourne crowd, though, and began to make Sabalenka play one extra ball, forcing the errors.
After levelling at 5-5, Gauff broke when Sabalenka missed a sitter on top of the net but the champion stayed calm, broke back, took the tiebreak and grabbed one break in the middle of the second set to clinch victory.
“I had chances in both sets, but she played better tonight,” Gauff said. “I felt like I did my best with the gameplan that I had. I think it just came down to a couple of points.”
Men's singles R4: Andrey Rublev [5] beat Alex de Minaur [10] 6-4 6-7(5) 6-7(4) 6-3 6-0
With wins over Novak Djokovic and Alexander Zverev at the United Cup, De Minaur broke into the top 10 for the first time and arrived at Australian Open 2024 as his country’s big hope for a first men’s champion since 1976.
In his way, though, was fifth seed Rublev, in top form and one of the biggest hitters on tour.
What proceeded was tennis brutality. The first three sets lasted more than three hours, with each man blazing groundstrokes at each other like they were missiles.
De Minaur led two sets to one and looked the stronger, but when Rublev began to struggle physically he just cut loose.
On another day, De Minaur might have finished him off but everything went in for Rublev and with the Aussie’s spirit crushed, he ripped through the fifth.
Men's singles F: Jannik Sinner [4] beat Daniil Medvedev [3] 3-6 3-6 6-4 6-4 6-3
In a tournament with a total of 35 five-set matches, equalling the Open era record with the 1983 US Open, it seemed fitting that the AO 2024 finale also went the distance.
Jannik Sinner was surprised by Daniil Medvedev's first-strike tactics, with the third seed's aggressive return position, powerful groundstrokes and frequent trips to the net helping him pocket the opening set and build a big lead in the second.
However, the momentum of the match began to shift as Medvedev's cumulative court-time began to catch up with him, and Sinner settled more into his first Grand Slam final.
The young Italian began to hit out more freely, and, buoyed by a vocal crowd at Rod Laver Arena, began to reel Medvedev in.
Several memorable rallies unfolded in a compelling fourth set, which Sinner won to send the match to a decider.
Growing in confidence, Sinner built a 5-2 lead, and two games later found himself serving for the title; he successfully closed it out with one final scorching forehand winner down the line.
