MONTREAL -- Serena Williams has pulled out of next week's Rogers Cup hard-court tournament, citing personal reasons.
The tournament announced Williams' withdrawal on Saturday.
The 23-time Grand Slam champion is coming off the most lopsided defeat of her career, a 6-1, 6-0 loss to Johanna Konta in San Jose, California, on Tuesday.
Williams, 36, was the runner-up at Wimbledon last month. That was just her fourth tournament since returning to the tour after having a baby in September and dealing with a health scare related to blood clots.
The year's last major tournament, the US Open, starts on Aug. 27.
