In an interview to The New York Times the former Roger Federer's coach Paul Annacone commented on Sloane Stephens's potential. Annacone worked with his compatriot in 2014. He said: "With Serena not full time anymore, to me Sloane is the most talented woman on the tour.
I think she’s just a freak of a talent. She’s one of those players who can snap out of it at any moment. I wouldn’t be surprised at all if she’s playing for the title again in Paris. I think every player has a default mode under great pressure, and I think her default mode is reactive.
Her default mode is: ‘I’m a great mover. It’s a big moment, and I’m going to move, and I’m not going to miss.’” Recalling her 2018 French Open final loss to Simona Halep, Stephens added: “It just wasn’t my time.
She was bound to win a Slam, and that was just how it was supposed to be. I can accept that fully”. On how her life has changed since her 2017 US Open triumph, Stephens added: “I was living such a normal life. And then I decided — well, I didn’t decide — but it just so happened that I played a month of insane tennis, and I was like: ‘I’m not ready for this, like, I don’t want to be ready for this.’ I woke up the day after the final, and I was like, ‘Damn, what did I just do?’”
