USTA Foundation on Instagram: "Tiafoe showed up big time for the next generation in Miami—hitting the courts with @delrayfoundation and dropping life lessons during his first-ever “Tiafoe Talk” with @firstservemiami. We’re grateful for his heart, his commitment, and his dreams for the next generation of leaders on and off the court. 👏 #ustafoundation #francestiafoefund #tennis #njtl"
