Most Grand Slam Match Wins in a Single Season

At the top of the Open Era list for Most Grand Slam Wins in a Single Season stands a shared ceiling of 27 major match wins — one short of the theoretical maximum of 28. The record has been reached multiple times by Novak Djokovic in near-perfect Slam seasons, and once by 🇨🇭 Roger Federer in 2006.

A special historical case remains 🇦🇺 Rod Laver in 1969: he is the only player to win every Grand Slam match he played in a single season, completing the calendar-year Grand Slam with 26 wins and an unbeaten record. That total is lower than modern top totals because the draw structure of that era required fewer matches.

🇨🇭 Roger Federer was the first modern player to hit the mark, recording 27 Grand Slam wins in 2006: he won the Australian Open, Wimbledon and the US Open, and reached the Roland Garros final, losing only once at the majors all season. He repeated the same total in 2007, again winning three Slams and reaching the French Open final.

🇷🇸 Novak Djokovic later matched the record in three different seasons. In 2015, he won the Australian Open, Wimbledon and the US Open, and reached the Roland Garros final. In 2021, he again reached 27, winning the first three majors of the year before losing the US Open final. In 2023, he recorded another 27-win Slam season by winning the Australian Open, Roland Garros and the US Open, while finishing runner-up at Wimbledon.

Behind the 27-win ceiling come other elite near-perfect seasons: 🇮🇹 Jannik Sinner reached 26 Grand Slam wins in 2025, while Djokovic also had 26 in 2011 and Federer had 26 in 2009.

In this record, the milestone is not simply winning Slams, but maintaining near-total consistency across all four majors in the same year: 27 wins means reaching all four finals and winning three titles, or producing an equivalent near-perfect Slam campaign. Federer set the modern benchmark first in 2006, while Djokovic became the great repeat case, matching the ceiling in 2015, 2021 and 2023.
