Remember that fiery Vienna Open clash when Big Foe got under Sinner’s skin? The World No. 1 called Tiafoe out for 'disrespect' after losing his only match to him, but since then, Sinner’s been unstoppable—matching Federer’s hard-court record and gunning for another US Open title. Their rivalry is all about contrasting styles: Sinner’s ice-cool focus vs. Tiafoe’s crowd-pleasing energy. If they meet in New York, expect fireworks! #Sports #USOpen #Sinner
