INDIAN WELLS, Calif. (AP) — Nikoloz Basilashvili outlasted No. 2 seed Stefanos Tsitsipas 6-4, 2-6, 6-4 Friday to move into the semifinals of the BNP Paribas Open with the biggest win of his career.
Basilashvili next plays either No. 3 Alexander Zverev or American Taylor Fritz, who met in a later quarterfinal at the Indian Wells Tennis Garden.
The women's semifinals Friday night featured Victoria Azarenka against Jelena Ostapenko and Ons Jabeur against Paula Badosa.
Ranked 36th in the world, Basilashvili's previous biggest win came over then-No. 4 Juan Martin del Potro in the final at Beijing in 2018.
The 29-year-old from Georgia beat Tsitsipas for the first time in three tries. Ranked third, Tsitsipas has a leading 54 wins on the ATP Tour this year.
