INDIAN WELLS, Calif. — Aryna Sabalenka held off Victoria Mboko 7-6 (0), 6-4 in the quarterfinals of the BNP Paribas Open on Thursday, keeping the top-ranked player in women’s tennis in the running for her first title at Indian Wells.
After winning every point in the first-set tiebreaker, Sabalenka got the one break she needed to win the second set and move on to the semifinals against 14th seed Linda Noskova of Czechia, a 6-2, 4-6, 6-2 winner over unseeded Australian Talia Gibson.
In the men’s draw, second-seeded Jannik Sinner of Italy defeated 25th-seeded American Learner Tien 6-1, 6-2, ending the run of the youngest American — at age 20 — to play in a quarterfinal at Indian Wells since his coach, Michael Chang, won the tournament in 1992.
Sinner, who served 10 aces and double-faulted only once, will play his semifinal match on Saturday against German Alexander Zverev, a 6-2, 6-3 winner over France’s Arthur Fils.
Sabalenka hasn’t lost a set in the tournament but was pushed by the 10th-seeded Mboko, a 19-year-old Canadian who won the 2025 Canadian Open.
Sabalenka put 94% of her first serves in play and was not broken, but did fight off five break points.
“I was focused on my game plan. I was just playing point by point,” Sabalenka said. “I’m pretty happy with the way I’m serving so far.”
