Carlos Alcaraz reasserted his superiority over Jannik Sinner with a 6-2, 3-6, 6-1, 6-4 victory Sunday in the U.S. Open final — the third Grand Slam tournament in a row where these elite, young rivals met to decide the champion — for 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 thousands of fans were still outside in line, trying to get through the extra security measures in place because of the presence of a sitting president at the tournament for the first time since Bill Clinton in 2000.

Perhaps the extra wait got the No. 1-seeded Sinner, who was the defending champion.

Right from the beginning under a closed roof because of rain earlier in the day, No. 2 Alcaraz was better as he sought to reverse the result from when they met at the All England Club less than two months ago.

He did just that, putting his leads over Sinner at 10-5 in their head-to-head series, 6-4 in major trophies, and 2-1 in U.S. Open championships. Plus, this win allowed Alcaraz, a 22-year-old from Spain, to take away the No. 1 ranking from Sinner, a 24-year-old from Italy.

These two guys are so, so much better than the rest of men’s tennis at the moment.

They have combined to collect the past eight Slam trophies in a row, and 10 of 13. Novak Djokovic, whom Alcaraz eliminated in Friday’s semifinals, took the other three in that span.

Sunday’s showdown represented the first time in tennis history that the same two men played each other in three consecutive Slam finals within a single season.
