Hold onto your seats, tennis fans, because the Australian Open just delivered a jaw-dropping upset that no one saw coming! Elsa Jacquemot, the 58th-ranked Frenchwoman, stunned the tennis world by defeating No. 20 seed Marta Kostyuk in a historic triple-tiebreak thriller. This wasn’t just any match—it was the first of its kind at the Australian Open in the Open Era, clocking in at a grueling 3 hours and 31 minutes. But here’s where it gets even more dramatic: Jacquemot clawed her way back from a set and 5-3 down, saving a match point in the process, to claim her first-ever Top 20 victory. Talk about a comeback for the ages!
And this is the part most people miss: Kostyuk, who had been on fire this season with three Top 10 wins under her belt, seemed unstoppable just weeks ago. Her pre-season strength training had paid dividends, and she was eyeing a Top 10 finish this year. But against Jacquemot, her 67 winners were overshadowed by 68 unforced errors. Was it Jacquemot’s relentless defense or Kostyuk’s over-pressing that tipped the scales? The debate is wide open.
Jacquemot, the 2020 Roland Garros junior champion who cracked the Top 100 last year, didn’t just defend—she strategically attacked. Her well-timed aggression, including ferocious forehand returns, kept Kostyuk off balance. Even a rolled ankle during the decider couldn’t save Kostyuk, as Jacquemot’s precision in the tiebreak sealed the deal. But here’s a thought: Could Kostyuk’s early-season success have set her up for this unexpected stumble?
This match marked only the fifth triple-tiebreak Grand Slam contest in the Open Era, joining an elite list that includes legends like Stefanie Graf. Fun fact: The Australian Open only introduced the third-set tiebreak in 2019, making this scoreline a rarity here. At the tour level, it was the 13th such match this decade—and the second of 2026 alone, following Madison Keys’ similar triumph in Brisbane.
Next up for Jacquemot? Former No. 20 Yulia Putintseva, who didn’t just win her match against Beatriz Haddad Maia—she owned it. Down a set and a break, Putintseva rallied to victory in 2 hours and 53 minutes, capping it off with a celebration that’s already a contender for the year’s best. Her shimmy and theatrical bow to the crowd on Court 6 were pure gold. But will her theatrics translate into another win against Jacquemot? Only time will tell.
Meanwhile, the tournament said goodbye to another seed: No. 32 Marketa Vondrousova, the former Wimbledon champion, withdrew due to ongoing shoulder issues. ‘I need to prioritize my health,’ she shared in a heartfelt statement. Lucky loser Taylor Townsend stepped in but fell to Hailey Baptiste in a three-set battle.
So, here’s the big question: Is Elsa Jacquemot a one-match wonder, or is she poised for a deep run at the Australian Open? And what does Kostyuk’s loss mean for her Top 10 aspirations? Let us know your thoughts in the comments—this is one tennis conversation you won’t want to miss!
