Stéfanos Tsitsipás defeated Milos Raonic 6–2, 6–3, 6–4 in the first round of the US Open on hard court, confirming his status as the pre-match favourite with a commanding performance. The Greek fifth seed required just over two hours to dismantle the Canadian, who offered little resistance across three straightforward sets. Tsitsipás controlled proceedings throughout, dictating play and limiting Raonic's opportunities to impose his serve-based game. The result was emphatic and unsurprising given the odds, with Tsitsipás advancing smoothly into the second round while Raonic's campaign ended in disappointing fashion on the New York hard courts.
