LINZ, Austria - Top-seeded Eugenie Bouchard of Canada pulled out of the Generali Ladies with a left leg injury on Thursday.
Bouchard had her thigh taped during Wednesday's win over Patricia Mayr-Achleitner, and said the injury worsened overnight.
"I woke up this morning and it was much, much worse," she said. "It's hard for me to keep playing and keep making it worse."
The sixth-ranked Bouchard is enjoying a breakthrough season in which she won her maiden WTA title in Nuremberg in May, reached the final at Wimbledon and the semifinals at the Australian and French Opens.
Bouchard said she didn't want to put her participation in the WTA Finals in Singapore at risk.
"The plan is to take a lot of days off right now and really rest," she said. "The goal is to try play Singapore in a week and a half. I won't have ideal training probably but I'll give it my best."
