Naomi Osaka Advances to Indian Wells Semifinals with Stunning Upset Over Aryna Sabalenka

Naomi Osaka turned back the clock Tuesday afternoon at the BNP Paribas Open, delivering a stunning 6-4, 7-5 upset victory over second-seeded Aryna Sabalenka to reach the semifinals of Indian Wells and continue her remarkable comeback to the top of women's tennis.

Osaka, playing in just her third tournament since returning from maternity leave in January, looked every bit the four-time Grand Slam champion who once dominated the sport. The Japanese star served brilliantly throughout the match, firing 12 aces while winning 78% of her first-serve points against one of the tour's most powerful players.

"I'm honestly shocked at how well I played today," Osaka said during her on-court interview. "Aryna is such an incredible player, and I knew I had to be at my absolute best. To beat someone of her caliber gives me so much confidence moving forward."

The victory marks Osaka's biggest win since her return to professional tennis, following an 15-month hiatus during which she gave birth to her daughter Shai. The former world No. 1 had struggled in her first two tournaments back, losing in the early rounds, but showed steady improvement throughout her Indian Wells run.

Sabalenka, who entered the match as the heavy favorite, struggled with her typically reliable serve and committed 6 double faults in a frustrating defeat. The Belarusian had been in excellent form leading up to the quarterfinal, dropping just one set in four previous matches at the tournament.

Osaka's semifinal opponent will be either Jessica Pegula or Qinwen Zheng, with the 26-year-old now just two wins away from capturing her first WTA title since the 2021 Australian Open. Her resurgence has been one of the most compelling storylines of the early 2026 season.

The victory also moves Osaka back into the top 50 of the WTA rankings for the first time since her return, serving notice that she intends to be a factor at the highest levels of women's tennis once again. Her combination of power, athleticism, and big-match experience makes her a dangerous floater in any tournament field as she continues building toward the upcoming clay court season.
