Alcaraz finished 2025 as the season’s surface king.
ATPTour.com’s Best Of series rounded up a year that mixed dominance and surprise, and this story breaks down who owned clay, grass and hard courts in 2025, with Carlos Alcaraz leading the way across multiple surfaces in the Infosys Index.
Alcaraz Dominates Clay and Grass
My Tennis Expert believes Alcaraz’s 2025 campaign confirmed his all-court mastery.

On clay Alcaraz was nearly untouchable, posting a remarkable 22-1 record and the season-best winning percentage of 95.7. His Roland Garros final win over Jannik Sinner was the headline, and that form cemented his claim as the surface leader across the ATP’s metrics for 2025. Also showed tactical variety.
Behind him Sinner finished with an impressive 11-2 clay ledger and an 84.6 winning percentage while Lorenzo Musetti and Alexander Bublik also broke through with consistent results. Jack Draper’s rapid improvement showed in finals appearances, including a surprise run to the Madrid final and a Rome quarter-final.
Grass: Momentum And Narrow Margins
Grass was another strong chapter for Alcaraz, who extended a career-best streak to 24 matches and added a Queen’s Club crown before reaching his third straight Wimbledon final. He finished with a grass record of 11-1 and a winning percentage of 91.7, edging Sinner overall in the numbers.
Taylor Fritz led the tour in grass wins with a 13-2 mark and an 86.7 winning rate, turning titles in Stuttgart and Eastbourne into Wimbledon semi-final momentum. Alexander Bublik and Novak Djokovic also posted strong percentages, each listed at 83.3 with limited matches but big moments.
Hard Courts And Indoor Strength
Hard courts belonged to Jannik Sinner in 2025, where he led the Infosys index with a winning percentage of 92.9 and a crushing 39-3 record across the season, claiming five hard-court titles and defending his Australian Open crown during a dominant stretch on the surface.
Shanghai produced one of the season’s biggest shocks when World No. 204 Valentin Vacherot captured the Masters 1000 title, becoming the lowest-ranked champion at that level and finishing with a hard-court winning percentage of 85.7 and a 12-2 mark that turned heads.
Carlos Alcaraz was never far behind on hard courts, adding four trophies including the US Open and posting a season hard-court ledger of 38-7 with a winning percentage of 84.4, numbers that helped him reclaim the World No. 1 ranking late in the year.
Jack Draper grabbed his first ATP Masters 1000 crown in Indian Wells, while Novak Djokovic added another title to reach a career milestone with his 101st. Those achievements rounded out a season where depth and surprise results surged alongside the established stars’ consistency.
Indoors was perhaps Sinner’s cleanest stretch, going a flawless 15-0 with three consecutive titles in Vienna, Paris and the Nitto ATP Finals and extending his indoor streak to 31 wins. That perfect indoor record registered as a 100 percent winning rate in the Infosys index.
Other indoor performers included Ugo Humbert with an 11-2 record and an 84.6 percentage, Casper Ruud and Felix Auger-Aliassime with solid runs and more hardware. Alcaraz also notched his first indoor triumph in Rotterdam and reached the Turin final, showing his range under a roof.
At 22 years old Alcaraz reclaimed the ATP Year-End No. 1 presented by PIF and led the Infosys ATP Win/Loss Index on two of the three surfaces, underlining an all-court mastery that combined dominance with enough drama to define the 2025 season for fans and analysts alike.
The Alcaraz-Sinner rivalry defined many big finals, with Sinner taking Wimbledon and Alcaraz taking Roland Garros; Sinner’s consistency on hard and indoor courts, including five hard titles and a perfect indoor run, keeps him as the clearest challenger to Alcaraz across surfaces and sets up electric rematch potential for 2026.
History will remember 2025 as a season where youth collided with experience, and the rankings shuffled as Alcaraz reclaimed the summit at age 22. Expect both players and a deep field to chase marginal gains on each surface, and fans should take note.
