Coco Gauff’s shoes carried the message “Play for Peace” as she joined Rafael Nadal, Iga Swiatek and other tennis stars in a pre-U.S. Open exhibition event that helped generate more than $1 million for humanitarian assistance in Ukraine. Gauff teamed with former player John McEnroe in a mixed doubles match against Nadal and Swiatek. The U.S. Tennis Association said 100% of proceeds from sales of tickets to its “Tennis Plays for Peace Exhibition” in Louis Armstrong Stadium went to an international nonprofit organization. Other players participating included Ukrainian pros Dayana Yastremska and Katarina Zavatska, 2021 U.S. Open finalist Leylah Fernandez, Carlos Alcarez, Maria Sakkari, Stefanos Tsitsipas and Jessica Pegula.
