The 5 greatest men’s Grand Slam duopolies: Alcaraz & Sinner with 7 straight majors
Jannik Sinner and Carlos Alcaraz’s domination of tennis continues to break new ground.
Sunday’s Wimbledon final, in which the Italian prevailed in four sets to win his fourth Grand Slam title, was the second straight Grand Slam final between the two.
And, it was also the seventh straight Grand Slam in which one of Sinner or Alcaraz had lifted the title, a run dating back to the start of 2024.
In the Open Era, there have been only five occasions in which two male players have combined to win at least seven straight Grand Slams, with both men involved winning at least two titles.
Here, we look at the five greatest Grand Slam men’s singles duopolies of the Open Era.
=4) Carlos Alcaraz & Jannik Sinner, 7 Grand Slams* (2024 Australian Open – 2025 Wimbledon)
Title split: Sinner 4 titles, Alcaraz 3 titles
This one is asterisked, largely because it seems more than possible that Alcaraz and Sinner could yet sweep several more majors together.
After Novak Djokovic’s triumph at the 2023 US Open, Sinner proceeded to win his first major title at the 2024 Australian Open, before Alcaraz completed the rare French Open-Wimbledon double last summer.
Sinner extended his hard-court dominance with 2024 US Open and 2025 Australian Open triumphs, before Alcaraz beat the Italian in a thrilling French Open final last month.
The two were guaranteed to win a seventh straight major when they met in the Wimbledon final, with the world No 1 prevailing on this occasion.
=4) Rod Laver & Arthur Ashe, 7 Grand Slams (1968 Wimbledon – 1970 Australian Open)
Title split: Laver 5 titles, Ashe 2 titles
Alcaraz and Sinner are now level with tennis icons Laver and Ashe, who split seven straight majors between them across the late 1960s and early 1970s.
After losing the 1968 French Open final to Ken Rosewall, Laver rebounded to triumph at Wimbledon, before Ashe triumphed at the 1968 US Open to claim his first Grand Slam title.
1969 saw Laver sweep all four Grand Slam titles, remaining the last man to complete the Calendar Slam, before his run was snapped after withdrawing from the 1970 Australian Open – where Ashe triumphed.
With Laver absent and Ashe beaten in the last eight, their duopoly was snapped at the 1970 French Open by Jan Kodes.
3) Novak Djokovic & Rafael Nadal, 8 Grand Slams (2018 Roland Garros – 2020 Australian Open)
Title split: Djokovic 5 titles, Nadal 3 titles
The first of two Djokovic and Nadal duopolies on this list, the legendary rivals combined to win eight straight majors between the 2018 French Open and 2020 Australian Open.
Nadal triumphed at Roland Garros in 2018, before a resurgent Djokovic swept both Wimbledon and the US Open, before beating the Spaniard in the 2019 Australian Open final.
The French Open again went the way of Nadal that spring, and, after Djokovic defended his crown at SW19, the Spaniard claimed the fourth and final US Open title of his career.

Djokovic rebounded to triumph at the 2020 Australian Open, though, with the Serbian defaulted and Nadal absent, their run was broken at the 2020 US Open by Dominic Thiem.
2) Novak Djokovic & Rafael Nadal, 9 Grand Slams (2010 Roland Garros – 2012 Roland Garros)
Title split: Nadal 5 titles, Djokovic 4 titles
Before their run of eight straight Slams, Nadal and Djokovic went on a run of nine straight Grand Slam titles from the 2010 French Open to the 2012 French Open.
After regaining his Roland Garros crown in 2010, Nadal swept the Wimbledon and US Open titles that summer, before Djokovic ended his wait for a second Grand Slam title at the 2011 Australian Open.
Nadal would again triumph at Roland Garros in 2011, though Djokovic would then win his first Wimbledon and US Open titles that summer, before winning the Australian Open for a third time.
Victory at the 2012 French Open versus Djokovic saw Nadal make it nine straight Slams between the two, before Roger Federer snapped their duopoly with his 2012 Wimbledon victory.
1) Roger Federer & Rafael Nadal, 11 Grand Slams (2005 Roland Garros – 2007 US Open)
Title split: Federer 8 titles, Nadal 3 titles
Currently, the longest Grand Slam men’s singles duopoly of the Open Era saw Federer and Nadal combine to win a staggering 11 straight majors.
The streak started with Nadal winning his first French Open title in 2005, before Federer went on to defend his Wimbledon and US Open titles later that summer.
The Swiss would then regain the Australian Open title in 2006 before losing to Nadal in the Roland Garros final, though he again triumphed at SW19 and Flushing Meadows that summer.
That same pattern continued across 2007, with Federer sweeping three of the four majors outside of Paris, where Nadal claimed a third straight French Open title.
Their run was eventually snapped at the 2008 Australian Open, which saw Djokovic win the first of his 24 major titles.
