15-year-old Coco Gauff capped a day of stunners at Wimbledon with perhaps the biggest of all, defeating 7-time Grand Slam champion Venus Williams in straight sets, 6-4, 6-4.

Gauff became the youngest player to win a main-draw match at Wimbledon since Jennifer Capriati in 1991. Williams had won four Grand Slam titles before Gauff was born in 2004.

The American youngster recorded 18 winners while making just eight unforced errors and won 78 percent of her first-serve points.

Gauff needed her fourth match point to seal the victory, with Williams sending a forehand into the net to complete the upset.
