Coco Gauff's fairytale introduction to Wimbledon continued with a second-round victory that belied her years over Magdalena Rybarikova.
The 15-year-old American qualifier needed just one hour nine minutes to beat her Slovakian opponent 6-3 6-3 under Court One's new roof.
Gauff, who beat five-time Wimbledon champion Venus Williams on Monday, will play Slovenia's Polona Hercog next.

"I played well on pressure points, she was serving amazing. I've not been able to relax, there is so much going on.
"I believe I can beat anyone across the court.
