WIMBLEDON, England (AP) — Mom and racket-holding Dad joined two coaches and a hitting partner at Coco Gauff’s practice session on a cloudy Sunday afternoon at the All England Club as the 15-year-old American prepared for what could be the toughest test yet of her hard-to-believe Grand Slam debut.

A qualifier who is ranked 313th and the youngest player to make it to Week 2 at Wimbledon since Jennifer Capriati in 1991, Gauff put in extra work on her forehand as she got ready to face former No. 1 Simona Halep in the most-anticipated matchup of the fourth round when the tournament resumes Monday.

“I don’t know a lot about her,” said Halep, the 2018 French Open champion.

For all that she’s already accomplished over the past 1½ weeks — including a victory over seven-time major champion Venus Williams — and all of the attention she’s received — messages via social media from Michelle Obama, Beyonce’s mother and singer Jaden Smith thrilled her the most — what truly stands out about Gauff is her composure, both on and off the tennis court.

“You can kind of fake it ’til you make it,” said Gauff, who lives in Delray Beach, Florida. “But I’m not faking it, at least right now.”
