Carlos Alcaraz and Jannik Sinner’s rivalry became the defining competitive feud of men’s tennis in the 2020s. Their first ATP-level meeting came at the 2021 Paris Masters, when the 18-year-old Alcaraz upset Sinner in straight sets and damaged the Italian’s hopes of qualifying for the ATP Finals. Their rivalry quickly escalated in 2022: Sinner beat Alcaraz at Wimbledon and then defeated him again in the Umag final, but Alcaraz answered in an extraordinary US Open quarterfinal. After falling behind and saving a match point, Alcaraz survived a five-hour, 15-minute battle that ended at 2:50 a.m.—the latest finish in US Open history. He went on to win the tournament, claim his first major title, and become the youngest men’s world No. 1 of the Open Era.
The rivalry grew more volatile and consequential as both players accumulated major titles and ranking milestones. Sinner beat Alcaraz in the 2023 Miami and Beijing semifinals, while Alcaraz responded by snapping Sinner’s 19-match winning streak at Indian Wells in 2024 and defeating him in a physically punishing French Open semifinal. Their 2025 French Open final became an even greater reversal of momentum: Sinner led by two sets and held three championship points at 5–3 in the fourth, but Alcaraz saved them, forced a tiebreak, and ultimately won the longest French Open final ever played at five hours and 29 minutes. Five weeks later, Sinner beat the two-time defending champion in the Wimbledon final, ending Alcaraz’s 24-match winning streak and handing him his first loss in a major final. The pair then split the 2025 US Open and ATP Finals encounters, turning their rivalry into a succession of broken streaks, dramatic comebacks, ranking battles, and major-final reversals rather than a one-sided duel.
