Carlos Alcaraz has reasserted his superiority over Jannik Sinner with a 6-2, 3-6, 6-1, 6-4 victory in the U.S. Open final. Sunday’s showdown was the third Grand Slam tournament in a row where these elite, young rivals met to decide the champion. Alcaraz claimed his second trophy at Flushing Meadows and sixth overall at a major. President Donald Trump sat in a sponsor’s suite in Arthur Ashe Stadium and received a mix of cheers and boos when he offered a wave beforehand and again when he was shown on videoboards after the first set. The match’s start was delayed by about a half-hour because of extra security.
