Coco Gauff is in the market for a new coach.

Less than three weeks after Gauff was upset by Emma Navarro in the fourth round of the U.S. Open, Gauff and her coach Brad Gilbert have parted ways.

“Thanks to @CocoGauff and the entire team for an absolutely amazing summer run in 2023 and for 14 months of incredible team effort,” Gilbert wrote in a post on X on Wednesday.

“Coco, at just 20 years young, your future is incredibly bright, and I wish you nothing but continued success ahead. I’m excited for the next chapter in my Coaching career.”

Gauff also had a third-round exit at the Paris Olympics.

Nevertheless, Gauff, who had won the U.S. Open last year, struck a positive tone after this year’s exit.

“I feel like there’s 70 other players in the draw that would love to have the summer that I had, even though it’s [the] least, probably, [I’ve] done well during this time of the year,” she told reporters after losing to Navarro. “So many people want to be in the fourth round. So many people want to make the Olympics. So many people want to be flag bearer. It’s perspective.”

She said that her issues at the U.S. Open were part physical and part mental.

“I go down on my left side a lot on my serve, and it’s something I’m aware of, but it’s tough in the moment to, I guess, try not to do it,” Gauff said.

“It’s sometimes more of an emotional, mental thing, because if I go out on the practice court right now, I would make, like, 30 serves in a row. I’ve done it before,” Gauff said. “I think it’s also just kind of a mental hurdle that I have to get over when it comes. … But I definitely want to look at other things, because I don’t want to lose matches like this anymore.”

In addition to winning the U.S. Open last year, Gauff made it to the semifinals of this year’s Austalian Open and French Open.
