In the biggest upset of the 2025 Australian Open so far, 19-seed Madison Keys defeated world No. 2 Iga Świątek in a back-and-forth three-set semifinal early Thursday morning.
Entering as the tournament’s only athlete to win every set, five-time Grand Slam champion Świątek conceded more games to Keys than in her previous five Australian Open matches combined.
Keys’s speedy serve and heavy forehand paired with a Świątek double-fault pushed the match to a tie-break decider, with the US star ultimately winning 5-7, 6-1, 7-6 (10-8).
“It just became who can get that final point and who can be a little bit better than the other one,” Keys said post-match. “I’m happy it was me.”
Keys’s victory is just the latest chapter in a 2025 Australian Open run that’s seen her beat three Top 10 contenders in Świątek, No. 6 Elena Rybakina, and No. 10 Danielle Collins. Those victories earned the 29-year-old her own Top 10 spot in next Monday’s WTA rankings.
With Thursday’s win, Keys booked her second-ever Grand Slam championship match, returning to the sport’s top stage for the first time since the 2017 US Open.
One last challenge awaits Keys
To claim her career’s first Grand Slam trophy, however, Keys will have to defeat reigning champion and world No. 1 Aryna Sabalenka, who comfortably downed Spain’s No. 11 Paula Badosa 6-4, 6-2 on Thursday in pursuit of a third-straight Australian Open title.
In their five previous meetings, Keys has only beaten Sabalenka once, topping her in Berlin in 2021.
Sabalenka won their most recent bout in the 2023 US Open semifinals. However, that three-set slog was similar to Keys’s gritty victory over Świątek and, if she can maintain the composure and energy she displayed on Thursday, the US star’s momentum could fuel her to similarly stun Sabalenka.
