Cori Gauff, just 15, tackles 39-year-old Venus Williams in a Wimbledon generational clash on Monday with the history-making teenager counting Roger Federer as one of her cheerleaders.
Gauff, ranked at 313 and popularly known as 'Coco', is the youngest player ever to have qualified for Wimbledon. When she was born in 2004, five-time Wimbledon champion Venus had already won four Slams.
"I'm super happy for her," said Federer, whose management company Team8 handles the youngster's affairs.
"Everyone was waiting to see what the draw was like. I think that's fascinating, that she plays Venus.
"I think it's a great storyline. It will be a great, wonderful experience for Coco and Venus.
"Coco is a nice girl, works really hard. I think she's obviously got a wonderful future ahead of her." Gauff's background wasn't in tennis.
Growing up in Georgia, her father Corey played university basketball while mother Candi was a gymnast and athlete.
"I like tennis because you can only blame yourself and you can only control yourself," Gauff told wtatour.com
"Sometimes when I was on the basketball court I'd be trying to control other people, like, c'mon man, bring the ball up. I like the individual aspect - I like doubles too, but just one person on my team is enough."
