MADRID -- World No.2 Aryna Sabalenka ended No.15 Danielle Collins' 15-match winning streak in the fourth round of the Mutua Madrid Open, coming from a set down to defeat the red-hot American 4-6, 6-4, 6-3. The victory moved Sabalenka into her first WTA 1000 quarterfinal of the season.

A champion in Madrid in 2021 and 2023, Sabalenka is bidding to become the first three-time champion at the Caja Magica since Petra Kvitova. She will face 17-year-old Mirra Andreeva on Wednesday for a spot in her first WTA 1000 semifinal since 2023 Cincinnati. It will be a rematch of last year's fourth-round duel, which Sabalenka won handily, 6-3, 6-1. 

Tale of the tape: Buoyed by back-to-back titles in Miami and Charleston, No.15 Collins came into her fifth meeting against Sabalenka looking for her first win. All four of Sabalenka's previous victories came on hard courts, including three at the US Open.
