Big Foe’s US Open run ended in shocking fashion as Jan-Lennard Struff played lights-out tennis, but was it just Struff’s day or did the lightning-fast Grandstand court play a bigger role? Tiafoe admitted post-match that he struggled to find his rhythm and felt like the match was always on Struff’s racquet. The American crowd tried to lift him, but Struff’s power and composure sealed the upset. Tough loss for Tiafoe, who now drops out of the ATP top 30. What do you think—was it the court or just a bad day? #Sports #Tennis #USOpen
