After surviving a 23-double fault showing two days prior, Coco Gauff overcame another 14 in her win over Veronika Kudermetova to reach the Round of 16 in the National Bank Open.

It’s not often that the world No. 2 goes two months without winning a match, but that’s the reality Coco Gauff was facing late Tuesday night in Montreal, on the cusp of a third consecutive loss, this time in her opening duel at the Canadian Open.

Gauff's serve changes are still embedding into her tennis. But she has other ways to win when the double faults start.
