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'm still shocked I am even here," Gauff told BBC TV.

"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."

At such a tender age, Gauff is only eligible to play 10 tournaments at professional level between her 15th and 16th birthdays yet she appears to be taking the grand occasion of Wimbledon in her stride.

Earlier on Wednesday, she had trained briefly under the gaze of 18-time Grand Slam champion Rafael Nadal before being approached for a chat by Roger Federer, an eight-time winner in these parts, more than six hours before she finally got to play.

After a late court switch, the match finally got under way just after 20:00 BST, but Gauff looked at home straightaway against the world number 139, who reached the semi-finals at Wimbledon two years ago.

She broke 30-year-old Rybarikova's serve to love to go 4-2 up, losing just five points on her own serve throughout the entire first set.

Rybarikova, somewhat unsettled by the crowd's fierce support for Gauff, had her serve broken once again early in the second set.

But, showing glimpses of the form that saw her formerly become the world number 17, Rybarikova started to rally, twice defying Gauff on break point.

Yet this was always to be Gauff's night, seeing out the win by breaking serve once again.
