Defending champion Jannik Sinner battled past 25th seed Felix Auger-Aliassime 6-1, 3-6, 6-3, 6-4 in the U.S. Open semi-finals to book a blockbuster title clash with Carlos Alcaraz, renewing one of tennis’ most compelling rivalries.
Shortly after Alcaraz dismantled 24-time Grand Slam champion Novak Djokovic at Arthur Ashe Stadium, Sinner overcame moments of struggle but prevailed to reach his third straight major final against the Spaniard.
The hard-fought victory also makes Sinner only the fourth man in the Open Era (since 1968) to reach all four Grand Slam finals in a single season, joining Djokovic, Rod Laver, and Roger Federer.
“It’s been an amazing season. The Grand Slams are the most important tournaments and finding myself in another final, especially the last one of the year, is incredible,” said Sinner, who dealt with brief stomach discomfort mid-match but dismissed any fitness concerns.
Auger-Aliassime, competing in his second New York semi-final, fought valiantly and levelled the match after taking the second set, but Sinner’s powerful serving and composure in key moments carried him through.
Sunday’s final will mark the latest chapter in the Sinner-Alcaraz rivalry, three years after their memorable five-set quarter-final at Flushing Meadows.
The Italian won their Wimbledon final earlier this year, while Alcaraz triumphed in Paris, setting up a mouth-watering trilogy decider.
Would you like me to also add a rivalry comparison breakdown (head-to-head stats, titles this season, and surface records) to highlight the significance of the final?
