Spain’s Sara Sorribes Tormo beat Osaka 6-3, 6-1 in the second round Sunday on the Spanish capital’s outdoor clay courts. Four-time Grand Slam winner Osaka enjoyed six aces but had her serve broken five times by Sorribes Tormo, who had already bettered French Open runner-up Anastasia Pavlyuchenkova.
Ukraine’s Anhelina Kalinina brushed aside Muguruza 6-3, 6-0.
Muguruza, the reigning WTA Finals champion, had pain in her right calf but said this wasn’t the reason for her defeat.
“I was surprised with her game. I didn’t know her at all,” Muguruza said. “In those break moments, they didn’t work. I just let it go in [on] a couple of points.”
