American tennis prodigy Cori Gauff, 15, defeated Venus Williams in the first round of Wimbledon on Monday, becoming the youngest to win a match at the tournament since 1991.

Gauff defeated the five-time Wimbledon champion 6-4, 6-4. Magdalena Rybarikova awaits Gauff in the second round.

Gauff became the youngest ever to qualify for Wimbledon last week. She had been taking a high school test before her win over Belgium’s Greet Minnen to get into Wimbledon. When she learned she was going to face Williams in the first round, she called it a “dream,” according to BBC.

“I kind of felt like I was going to play one of them [the Williams sisters],” Gauff said. “Many people have been like 'do you like your draw?'  I love my draw. Playing one of the greatest players of all time is a dream -- I'm excited to see how I do.”

The Florida phenom had a previous run-in with tennis history when she was 13. She was the youngest to make a U.S. Open girls final and became one of the youngest players to win a French Open girls title at 14.

“My parents always told me to shoot as high as I wanted to,” she said before the tournament’s first round. “And I’m just happy that, not only did they accept my goals, they really sacrificed everything to make sure I get there.”
