Despite being selected to play this year, she ruled out the opportunity because of sponsorship engagements and to be mentally charged up for the singles.“For me, it was just because I know the free week of the US Open is already packed for me, for sponsor things, and it was just like a whole other thing. I’m very competitive, if I were to lose, I would not be happy. So, I didn’t want to waste mental energy on that," she said.The 21-year-old added:“I think it’s cool, and I think it’s going to be an exciting two days, and not knocking it off for the future. It’s just that I plan my sponsor weeks literally like a year out, sometimes a year and a half out. And when this whole thing was coming up, I was already booked and busy.”Gauff was the US Open champion in 2023 but missed defending the title in 2024.
