Frances Tiafoe credited a surprise pep talk from Serena Williams for inspiring his victory over Alexei Popyrin at the US Open, where he won 6-4, 7-6(3), 2-6, 6-3. Williams, who has not competed since her retirement in 2022, praised Tiafoe as a successful player of color, which deeply resonated with him. The six-time champion's presence at Flushing Meadows created excitement, and she also motivated Grigor Dimitrov before his match against Andrey Rublev. Tiafoe expressed that receiving encouragement from Williams was particularly impactful, noting, "It coming from her, I mean, it's just so loud." He will face Dimitrov in the quarter-finals, both inspired by Williams' support. The interaction highlighted the influence Williams continues to have in the tennis world even after her retirement.
