World No. 3 Coco Gauff exited the 2025 Australian Open on Monday night, falling 7-5, 6-4 to Spain's No. 11 Paula Badosa in the Grand Slam's quarterfinal round.
Gauff's recent improvements seemed to fade in her first loss of the year, which saw the 2025 United Cup champ record 41 unforced errors, including 28 missed forehands and six double-faults.
As a result, Badosa advances to her first-ever Grand Slam semifinal, a marked comeback after a 2023 injury nearly ended her career.
"I would never think that, a year after, I would be here," Badosa said post-match. "I've been through a lot."

Sabalenka looms after quarterfinal victory
Badosa moves on to face back-to-back defending champion Aryna Sabalenka on Thursday, as the world No. 1 sets her sights on becoming the first three-peat Australian Open women's champ this century.
Sabalenka advanced past No. 27 Anastasia Pavlyuchenkova in an early Tuesday morning quarterfinal to reach her 10th major semifinal in her last 11 Grand Slams.
The 6-2, 2-6, 6-3 victory didn't come easily, though, as Pavlyuchenkova managed to snap the 26-year-old's 25-set Australian Open winning streak which dates back to her 2023 final win.
"I’m really glad that at some point I was able to put myself back together," said Sabalenka about the tough match. "I was able to keep fighting, keep trying, and I was able to turn around this match. It was a really difficult one."

US players to close out Australian Open quarterfinals
The Melbourne Slam's remaining two quarterfinals each place a US tennis star in the spotlight on Tuesday.
Fresh off ousting No. 10 Danielle Collins and No. 6 Elena Rybakina in the third and fourth rounds, No. 19 Madison Keys will square off against No. 28 Elina Svitolina for a shot at the semis. This will be Keys's first match against the Ukrainian since taking a two-set victory over Svitolina in Adelaide in January 2022.
The nightcap pits three-set specialist No. 8 Emma Navarro against perennial contender No. 2 Iga Świątek, marking the second-ever meeting — and first since 2018 — between the 23-year-olds.
The Polish phenom has yet to drop a set all tournament, and has seemed near-unbeatable after losing just four games across her last three matches. That said, Navarro has proved she just won't quit, leading the WTA in three-set contests over the last year — and gritting out a 24-9 record in the same span. Consequently, the longer Tuesday's match runs, the more it will likely favor the US star.
