With Sunday's final match looming, the competition is heating up at the 2025 BNP Paribas Open at Indian Wells — though several top US players are no longer feeling the fire after falling short in the Round of 16.

Unseeded 28-year-old Swiss contender Belinda Bencic claimed arguably the tournament's biggest upset thus far, with the wild card ousting world No. 3 Coco Gauff on Wednesday.

Despite Gauff taking the first set, 2020 Olympic champion Bencic prevailed, fighting through multiple medical timeouts to snag the win.

Fellow US standout No. 4 Jessica Pegula suffered a similar fate, losing to Ukraine’s No. 23 Elina Svitolina in a three-set match heavily impacted by three hours of rain delays on Tuesday.

With the 5-7, 6-1, 6-2 come-from-behind win, Svitolina advances to her first Indian Wells quarterfinals in six years.

World No. 1 Aryna Sabalenka and defending Indian Wells champion No. 2 Iga Świątek continued their dominance through the Round of 16, with each booking their quarterfinals berth without dropping a single set at the tournament.

Bencic to face last-standing US player Madison Keys

Another US star stands between Bencic and Friday's semifinals, as 2025 Australian Open champ and freshly minted world No. 5 Madison Keys continues her winning form in California.

The endurance and tenacity that earned Keys her first-ever Grand Slam title is on display at Indian Wells, where she outlasted Belgium's No. 28 Elise Mertens after three back-and-forth sets on Monday before surviving a difficult battle against Croatia's No. 19-seed Donna Vekić in Wednesday’s Round of 16.

By winning the 4-6, 7-6 (7), 6-3 clash, Keys is now riding a 15-match victory streak into Thursday's quarterfinal.

"I kind of just started deciding I was going to go for a little bit more," she said afterwards. "Really happy to be able to get that match and get that win and play another match here."
