An absolute surprise at the Montreal Open after Coco Gauff's defeat to young Canadian Victoria Mboko. The world No. 2 was far from her usual level, and while she managed to reduce her double faults, she had a poor 43% first-serve percentage throughout the match and ended up losing 6-1,

After being pushed all the way by compatriot Danielle Collins in her first match in Montreal, Gauff was forced to dig deep yet again to seal a 4-6 7-5 6-2 win over Kudermetova

World number two Coco Gauff battled through another tough three-setter Thursday, rallying from a set and a break down to beat Veronika Kudermetova and reach the fourth round of the WTA Canadian Open.
