At only 15 years old, Cori Gauff is taking the tennis world by storm.

Gauff was the youngest United States Open junior girls finalist in history at age 13 and the second youngest French Open junior girls champion at age 14. Her rise to success and incredible talent has been whispered about for years.

Now, she’s been brought to the spotlight after a huge upset. Gauff took out star player Venus Williams, 6-4, 6-4, in the first round of Wimbledon. It was her first Grand Slam singles match of her career.

“On the court, I was not thinking about Venus,” Gauff said. “I was just playing my game. No matter who I play against, I want to win. So that’s what I was just thinking about the whole time. I wasn’t really thinking about who I was facing on the other side of the net.”

Now, it’s all Gauff can think about. After Gauff secured the win, she took the opportunity to thank Venus.

“I was just telling her thank you for everything she’s done for the sport,” Gauff said. “She’s been an inspiration for many people. I was just really telling her thank you. I met her before, but I didn’t really have the guts to say anything.”

While many are celebrating Gauff’s big win, what most people don’t know is Gauff’s love of the Christian faith. Gauff takes a moment to pray with her father, who is also her coach, before every match.

“Before every match since I was 8, my dad and I say a prayer together,” Gauff said. “We don’t really pray about victory, just that me and my opponent stay safe. After the match, I was just thanking God for this opportunity.”

Gauff also said a prayer as she was tearing up after her win against Venus.
