In 2025, Jannik Sinner has already carved out a Grand Slam season that stands shoulder to shoulder with some of the most commanding years in history, but the US Open still offers him the chance to step into even rarer company.
With titles at the Australian Open and Wimbledon either side of a run to the Roland Garros final, the No. 1 player in the PIF ATP Rankings is closing in on becoming the seventh man in the Open Era to win three Grand Slam titles in a single season. That bitter defeat to rival Carlos Alcaraz in Paris, in which he let slip three championship points, means that Sinner could enter an even rarer group in New York.
If Sinner successfully defends his title at the US Open, he would become just the fourth man to win three majors in a season and reach the championship match in the fourth, joining Roger Federer, Novak Djokovic, and Rod Laver.
The achievement of winning three major titles and reaching the final in the fourth is notoriously difficult to pull off. Federer’s triple-major years in 2006 and 2007 were denied perfection only by Nadal on the clay of Roland Garros. Djokovic has done it three times, but even he knows the sting of coming close to something bigger.
In 2021, the Serbian arrived at the US Open having won the first three major titles, only to fall at the last hurdle, where he was defeated in straight sets by Daniil Medvedev in the final. Time and time again, the season’s closing major has drawn the line between greatness and sporting immortality.

Sinner will step onto that stage at the US Open as defending champion and a proven force on hard courts. Despite seeing his 26-match winning streak on the surface snapped by his retirement against Alcaraz in the Cincinnati final, the 24-year-old Italian is unbeaten at the hard-court majors since his fourth-round loss to Alexander Zverev in five sets in New York in 2023.
If he were to win a fourth consecutive major title on the surface, and successfully defend his crown at the US Open, Sinner will stand alone as the first man to win three majors in a season and hold match points in the final of the other. It is a reminder of how human this pursuit can be, where history often hinges on single points.

Despite not coming within a point of victory, Djokovic knows that feeling too, having lost an absorbing five-set Wimbledon final to Alcaraz in 2023 — the same year he nonetheless won three Grand Slam titles in a season for the fourth time in his career.
Whatever unfolds for Sinner at Flushing Meadows, his 2025 campaign already carries the statistical weight and historical echoes of the game’s most dominant seasons. The reigning Nitto ATP Finals champion would mark his 300th career victory, according to the Infosys ATP Win/Loss Index, if he advances to the championship match.
