Carlos Alcaraz defeated Casper Ruud in the final, 6–4, 2–6, 7–6(7–1), 6–3 to win the men's singles tennis title at the 2022 US Open. It was his first major title. Alcaraz claimed the world No. 1 singles ranking for the first time with the win; Ruud, Rafael Nadal, Daniil Medvedev, and Stefanos Tsitsipas were also in contention for the top position. He saved a match point en route to the title, in the quarterfinals against Jannik Sinner. Alcaraz was the youngest men's major champion since Nadal at the 2005 French Open, the youngest US Open champion since Pete Sampras in 1990, the first man born in the 2000s and the first Generation Z to win a major singles title, and the youngest man to be ranked world No. 1, surpassing Lleyton Hewitt's record. At 23 hours and 39 minutes of play duration across his seven matches, Alcaraz spent the longest time on court in major history.
