Naomi Osaka bounced back from a second-set setback to defeat Katerina Siniakova in a thrilling three-set match at the US Open 2026. The two-time champion, dressed in a striking outfit inspired by NBA legend Allen Iverson, initially appeared on track for an easy victory after taking the first set 6-2 and leading 5-3 in the second.

However, Osaka faltered, allowing Siniakova to win four consecutive games and take the second set 5-7. After a brief bathroom break to regroup, Osaka returned to dominate the decider, sealing a 6-1 victory and a spot in the third round against Elise Mertens.

Osaka expressed her thoughts on the match, stating, "The match was definitely really tough. I just felt like I was a little bit too hard on myself after opportunities in the second set." Her win marked her 80th Grand Slam singles victory, making her the second Japanese woman in the Open era to achieve this milestone.

In contrast, Iga Swiatek, the former world number one and six-time major winner, had a smoother path, defeating Nadia Podoroska 6-3 6-2. She will face Marie Bouzkova in the next round.

Additionally, Madison Keys, the 22nd seed, overcame a dramatic match against Anna Bondar, saving five match points to clinch a victory in a nail-biting 10-point tie-break, winning 5-7 6-4 7-6 (10-5).

This year's tournament continues to showcase thrilling matches and remarkable performances from top players.
