Aryna Sabalenka held off a near-perfect performance from Naomi Osaka to reach the Mutua Madrid Open quarterfinals on Monday, defeating the former world No. 1, 6-7 (1), 6-3, 6-2.
The defending champion and world No. 1 trailed Osaka by a set and a break but roared back to book her spot in the last eight—and score a 150th WTA 1000 match win—after two hours and 20 minutes on Manolo Santana Stadium.
"That was an incredible level," Sabalenka said on court. "She played really incredible tennis. I feel like I just got lucky with a couple shots in the third set and that's why it went that fast. But overall, it was really an incredible fight. I had to level up my game and I'm happy with the performance."
Sabalenka, who previously shared an agent with Osaka, was playing her first tournament since securing the Sunshine Double in March, becoming the fifth different woman to win both Indian Wells and Miami in the same year. A three-time champion in Madrid, she was impressively efficient through her opening rounds over Peyton Stearns and No. 29 seed Jaqueline Cristian.
