NEW YORK (AP) — Eugenie Bouchard's revitalizing run at the U.S. Open is over after she slipped and fell in the locker room.
The 25th-seeded Canadian, diagnosed with a concussion, withdrew from her fourth-round match against Roberta Vinci on Sunday.
She was hurt Friday and pulled out of two doubles matches Saturday, hoping to still play in singles. But tournament officials announced Sunday that she had a concussion and had withdrawn.
The 21-year-old Bouchard, a runner-up at Wimbledon last year, had been struggling mightily coming into the U.S. Open but rediscovered her form at Flushing Meadows — with a boost from some work with Jimmy Connors.
Her ranking, as high as No. 5 last fall, had slipped to 25th, and she'd lost 14 of 17 matches before arriving in New York. But then she suddenly strung together her first three-match winning streak since January, capped by a grueling three-set victory Friday over 2014 Australian Open runner-up Dominika Cibulkova.
Bouchard was seen arriving at the tennis center Sunday with a hoodie pulled over her head, wearing dark sunglasses and walking gingerly.
The 32-year-old Vinci, whose ranking is down to 43rd, moves on to her first Grand Slam quarterfinal since the 2013 U.S. Open.
