French Open champion Garbine Muguruza of Spain pulled out of her opening match at the WTA hardcourt tournament in Montreal on Tuesday minutes before she was to take on Britain`s Naomi Broady.
Muguruza, the world number three who is seeded third in a tournament already hit by the withdrawal of Serena Williams, cited a gastrointestinal illness.
World number one Williams pulled out with inflammation in her shoulder over the weekend.
“I`m pretty disappointed, I practiced a lot for this tournament,” Garbine said. “Since yesterday, I have kind of been feeling weird and I spoke with the doctor and everything. I thought today I was going to feel better, but in the last moment I didn`t feel good enough to go on court and give my best.”
Although it was a second-round match, Muguruza enjoyed a first-round bye. Organizers filled her place in the draw with lucky loser Varvara Lepchenko of the United States, who stepped in at the last minute against qualifier Broady.
