Muguruza, ranked seventh in the world, was a semi-finalist in San Jose last year, falling to eventual champion Madison Keys.

Lucky loser Anna Blinkova of Russia replaces Muguruza in the draw to play Victoria Azarenka of Belarus in a second-round match on Wednesday night.

Former world number one Azarenka defeated Kateryna Bondarenko in three sets in the first round.

Muguruza’s withdrawal follows the shock first-round exit of 23-time Grand Slam champion Serena Williams, who fell 6-1, 6-0 to Britain’s Johanna Konta on Tuesday.

Williams, seeded sixth and playing her first match since she was beaten in the Wimbledon final by Angelique Kerber, suffered the most lopsided defeat of her career.
