Stat of the Year, No. 2: Carlos Alcaraz’s Double Surface Slam for the ages

The stars of the ATP and WTA rewrote history time and time again in 2025, and this week on TENNIS.com we’re celebrating some of their biggest achievements with our top five stats of the year.

So far this week, we’ve covered Jannik Sinner becoming the youngest player ever to reach the final of all four Grand Slams and the ATP Finals in the same season, Aryna Sabalenka breaking the record for most tie-breaks won in a row by a woman in the Open Era and Novak Djokovic becoming the first man in the Open Era to win a title in 20 different seasons.

Today, a multi-surface feat for the ages...

By winning Roland Garros in 2024, a 21-year-old Carlos Alcaraz became the youngest man in tennis history to win Grand Slam titles on all three surfaces—hard, grass and clay—having already won the US Open in 2022 and Wimbledon in 2023.

This year, he took it to another level.

By winning the 2025 US Open, at 22 years old, Alcaraz became the youngest man ever to win multiple Grand Slam titles on all three surfaces, having already won a second one on grass (2024 Wimbledon) and a second one on clay (2025 Roland Garros).

The previous record belonged to Mats Wilander, who completed his Double Surface Slam as a 24-year-old at the 1988 US Open.

Only two other men have achieved the feat, and they’re two of the usual suspects—Rafael Nadal, who did it at Wimbledon in 2010 as a slightly older 24-year-old than Wilander, and Novak Djokovic, who did it at Roland Garros in 2021 at age 34.

MEN TO WIN MULTIPLE MAJORS ON ALL THREE SURFACES (all-time):

• Mats Wilander [2 on hard, 3 on clay, 2 on grass]
• Rafael Nadal [6 on hard, 14 on clay, 2 on grass]
• Novak Djokovic [14 on hard, 3 on clay, 7 on grass]
• Carlos Alcaraz [2 on hard, 2 on clay, 2 on grass]

As of now, Djokovic is the only man ever to win three or more Grand Slam titles on every surface, completing his Triple Surface Slam on the clay courts of Roland Garros in 2023.

No man has ever won four majors on every surface.

The first Grand Slam to be played on hard courts was the 1978 US Open, and the Australian Open switched to the surface in 1988.
