While Gauff lost in the singles qualifiers to 11th seeded Heather Watson it was quite a remarkable feat to already be playing in the US Open at such a young age. The following year at the US Open Gauff continued to improve reaching the third round before losing to top seeded Naomi Osaka. While Gauff has not yet won a US Open she has not shied away from the big stage and there truly is no limit to her ceiling. She has already defeated Venus Williams at Wimbledon in 2019 and Naomi Osaka at the Australian Open in 2020 and in June of 2021 made her first ever appearance in a Grand Slam singles final appearing in the French Open final while also reaching the French Open doubles finals with her partner Jessica Pegula.This Wilson U.S. Open jumbo tennis ball is autographed by Coco Gauff. Gauff's signature was witnessed by an Upper Deck representative as part of UDA's 5-step authentication process. This item is not limited.
