Coco Gauff was upset Monday at Arthur Ashe Stadium by Naomi Osaka in the Round of 16 at the U.S. Open, and she admitted to reporters that it was a tough loss to handle emotionally.

Gauff said she "kind of broke down" to her team after falling 6-3, 6-2 in a shocking performance for the No. 3-ranked American star.

"After the match, I was really disappointed," Gauff explained. "Kind of broke down to my team. Then, hearing their perspectives and everything, it definitely is a lot of positive things. I think if I kept the way I was going in Cincinnati to her, I would have been out in the first round. So, I think where my serve started from the start of the tournament to today was a big improvement."

Before the final Grand Slam of the tennis season began, Gauff made a big coaching change, parting ways with Matt Daly and bringing in biomechanics expert Gavin MacMillan. 

The move was specifically done to help correct Gauff’s serve, and MacMillan has worked with some of the best in the game, including top-ranked women’s singles player Aryna Sabalenka, to get their serves right.

So, while that area of Gauff’s game felt improved in her eyes, she committed 33 unforced errors that were hard to overcome against Osaka, the two-time U.S. Open champion and No. 23-ranked player in the tournament this month.
