4 shocking results from Australian Open Day 10 ft. Coco Gauff & others

The 2025 Australian Open is headed towards its business end but there's still no death of surprises each day, with Coco Gauff's shock exit being the latest example. The American was a title favorite but was bundled out at the quarterfinal stage.

Gauff's exit had the tennis fans talking in the morning, but as the day progressed, more upsets unfolded both in the singles and the doubles categories.

Before we shift all our focus to the second day of singles quarterfinals action (set to take place on Wednesday), let's quickly rewind on how some of the biggest upsets on Day 10 of the 2025 Australian Open unfolded:

#4 John-Patrick Smith and Kimberly Birrell def. Kevin Krawietz and Ellen Perez

Mixed doubles often throws up wildcard winners but even so, few would have seen John-Patrick Smith and Kimberly Birrell take out Kevin Krawietz and Ellen Perez.

Both Krawietz and Perez have been ranked among the best doubles players recent years so their 2-6, 6-3, 6-10 loss is definitely hard to digest.

That said, the credit has to go to their opponents, who served impeccably on the day. The pairing of Smith and Birrell conceded only one breakpoint throughout the encounter and were kore decisive in the match tiebreaker, translating into the scoreline. They will face Olivia Nicholls and Henry Patten for a spot in the final.

#3 Sem Verbeek and Andre Goransson def. Mate Pavic and Marcelo Arevalo

Mate Pavic has a Career Slam to boast of in men's doubles and is one of most established names in the segment. He was the top seed with two-time French Open winner Marcelo Arevalo. But none of that mattered as Sem Verbeek and Andre Goransson are having that sort of a fortnight.

Both ranked outside the top-50, Verbeek and Goransson have just struck lightning in a bottle at this year's Australian Open, scripting one stellar win after the other.

Having come into the quarterfinals with three straight-sets wins (including one over 10th seeds Joe Salisbury and Neal Skupski), they thundered down big serves and broke their opponents the once each in the first and third sets to close out the 6-4, 4-6, 6-3 win. Standing between them and a maiden Slam final are Andrea Vavassori and Simone Bolelli.

#2 Novak Djokovic def. Carlos Alcaraz

Novak Djokovic is a 10-time former champ so classifying any match that he win as a shock could be viewed as a bit of a stretch. But most pundits and fans were leaning towards a Carlos Alcaraz win ahead of the duo's quarterfinal showdown.

And it looked like that would be the case after the first, which Alcaraz won 6-4 despite falling behind a break early. That's when Djokovic decided to up the ante. His average forehand speed went up 9 kmph and the backhand 8 kmph in a matter of minutes and suddenly Alcaraz found himself on the backfoot.

The dynamic Spaniard continued to put up a fight, mixing his fierce forehands with delicate touches but Djokovic was simply dialed in Anticipating every more before it was even made, the Serb was a step ahead at every point. He served out the win in four sets 4-6, 6-4,6-36- 4. Up next for him is Alexander Zverev.

#1 Paula Badosa def. Coco Gauff

Coco Gauff looked to be in menacing form, having made a clean 9-0 start to the season. All of that went out the window when she found herself at the receiving end of a barrage from Paula Badosa on Tuesday.

The third seed at this year's Australian Open was a major title contender. Her run, however, has been cut short by the Spaniard, who turned in a fine showcase of first-strike tennis against the former Grand Slam champ

Badosa more than doubles Gauff's 15 winners with her 31 and won 70% of the first serve points to take the contest 7-5, 6-3. She was clinical on the big points and will need the same level of quality in the semifinals if she wishes to derail Aryna Sabalenka's title defence.
