Brad Gilbert's voice is a constant in Coco Gauff's ears each time she takes the court. It was no different in the American's fourth-round match against former No. 1 Caroline Wozniacki.
From 'your time to make it physical now' to 'Let's not try to go through her', the instructions coming at the 19-year-old Gauff doesn't cease. Gauff, who signed on former ATP pro Pere Riba as coach earlier this summer, and subsequently added Gilbert as consultant, has enjoyed a breakthrough summer with two of her biggest tournament successes coming in Washington and Cincinnati. Things came to a boil on court in the fourth round. "Please just stop," Gauff directed at her box when the 61-year-old Gilbert offered more advice.
