Gauff hadn't played since losing in the first round at Wimbledon and appeared to have made a change to her serving grip during her time away

Coco Gauff survived hitting 23 double faults and 74 unforced errors to record her first win since her victory in the French Open final in June. The American, the top seed in Montreal, was two points from defeat against compatriot Danielle Collins but rallied to win 7-5, 4-6, 7-6 (2) in two hours and 55 minutes.
