Coco Gauff has made some deep runs at the Australian Open in the past, but she's never won the event. This year could be different, though, as Gauff continued her push toward her first Australian Open title Sunday.
Gauff — seeded No. 3 — didn't have an easy task, as she needed to push past Karolína Muchová to get the job done. The No. 19 women's player did give Gauff some trouble during the match, but not enough to throw her off her game. Gauff picked up the win 6-1, 3-6, 6-3, taking down Muchová and pushing into the quarterfinal for the third straight year.

The win bodes extremely well for Gauff, who has gone on to win every event in which she's beaten Muchová.

After some promising results at the Australian Open early in her career, Gauff has inched closer to winning the even in recent years. She was a semifinalist in 2024 and then reached the quarterfinals in 2025.
Getting back to the semifinals this time around will prove tough, as Gauff will take on Elina Svitolina on Tuesday. The two have played each other three times in the past, with Gauff picking up two wins in those meetings.
Svitolina upset Mirra Andreeva on Sunday to move into the quarterfinal round.
Learner Tien advances for U.S. on men's side
Learner Tien faced a tough task Sunday. With a win, Tien would advance to the Australian Open quarterfinal for the first time in his career. But that wouldn't be easy, as he needed to defeat three-time finalist Daniil Medvedev to get there.
Tien proved up to the task, however, winning in straight sets (6-4, 6-0, 6-3) to take down the higher-ranked Medvedev. With the win, Tien became the youngest man to reach that Australian Open quarterfinal since 2015.

Tien, 20, will look to continue that momentum when he takes on No. 3-ranked Alexander Zverev on Tuesday.
Zverev pushed past Francisco Cerundolo on Sunday. Elsewhere on the men's side, Alex de Minaur defeated Alexander Bublik to move into the quarterfinals.
