San Jose top seed Garbine Muguruza withdrew ahead of her match Wednesday night against Victoria Azarenka due to a right arm injury.
“I’ve been feeling some pain in my right arm for a couple of days and realized I am not ready to play the match, so hopefully I can recover for the next tournaments,” Muguruza said.
Instead of the Spaniard, Azarenka met lucky loser Anna Blinkova and rolled losing just one game.
Elise Mertens was also a winner.
