World number one Karolina Pliskova crashed out of the Rogers Cup in Toronto after losing a marathon three-set quarter-final to Caroline Wozniacki.
Czech top seed Pliskova, under pressure from Romania's Simona Halep to stay at the top of the WTA rankings, lost 7-5 6-7 (3/7) 6-4 to Wozniacki in a thrilling contest, which was delayed by rain three times.
Pliskova, elevated to top spot last month despite her second-round Wimbledon exit, raced into a 5-1 lead in the opening set but Wozniacki, seeded sixth, rattled off the next half-dozen games to take it 7-5.
Pliskova, US open finalist last year and French Open semi-finalist in June, levelled the match in a second-set tie-break and led by a break in the decider, but Wozniacki hit back with two successive breaks to seal victory in two hours and 56 minutes.
