Julian Cash & Lloyd Glasspool
Julian Cash and Lloyd Glasspool produced a season that will be etched in British tennis history. In their first full campaign together, they finished as Year-End ATP Doubles No. 1 presented by PIF Honours, becoming the first all-British duo to achieve the feat. They won seven titles on Tour in 2025, including a run of five consecutive trophies between June and August, a run in which they went unbeaten for 22 matches.
“It’s been a crazy year, that’s for sure. We put a ton of work into the offseason. I couldn’t have done it without everyone in the box, including my family there in the corner,” Cash said as he collected the year-end trophy at the Nitto ATP Finals. “We checked off so many boxes this year and I think at the beginning of the year we both really believed that this was possible for us.”
One of the defining moments of Cash and Glasspool’s season came at Wimbledon, where they became the first all-British team since 1936 to win a major trophy in men’s doubles, sealing a first Grand Slam title for both players.

Harri Heliovaara and Henry Patten
For Harri Heliovaara and Henry Patten, 2025 told a story of starting strong and ending even stronger. The British-Finnish duo opened the season by winning their second major title at the Australian Open and then ended the year in dominant fashion, capturing their first ATP Masters 1000 crown in Paris before capping it off with a maiden win at the Nitto ATP Finals in Turin.
“It’s hard to describe,” Heliovaara said after winning the Nitto ATP Finals. “All week I’ve been looking at the winners list, with huge winners, and I thought, if my name was ever on there, I would be so proud. To be there next to Henry is surreal.”
After also winning the ATP 500 event in Beijing, Heliovaara and Patten finished the season with a record of 50–20, according to the Infosys ATP Win/Loss Index.
Marcel Granollers and Horacio Zeballos
After three previous defeats in major finals, Marcel Granollers and Horacio Zeballos turned heartache into redemption not once, but twice in 2025. First came a thrilling victory in the Roland Garros title match against Joe Salisbury and Neal Skupski, followed by an even more dramatic victory at the US Open, where they saved three championship points to triumph again over the British duo.
“Honestly, I don’t know what to think right now. It was a great battle,” Zeballos said at the US Open awards ceremony. “When you play games like this it’s so unfair when there’s a winner and a loser because the boys did everything great.
“I can’t believe we just won the US Open. It’s so nice to be here and have all these people watching us.”
Granollers and Zeballos, who also triumphed in Bucharest, Madrid and Basel, ended the season by participating in the Nitto ATP Finals for the sixth consecutive time.

Marcelo A & Mate Pavic
Marcelo Arevalo and Mate Pavic delivered another statement year, highlighted by ATP Masters 1000 titles in Indian Wells, Miami and Rome, securing a well-deserved return to the season finale in Turin. They became only the sixth team in history to complete the ‘Sunshine Double’, winning at Indian Wells and Miami in the same season.
Although Arevalo and Pavic fell behind Granollers and Zeballos in the Madrid final, they bounced back in Rome, saving a championship point by beating Sadio Doumbia and Fabien Reboul – a fitting redemption after losing the 2024 final.
“It means a lot, I’m really emotional right now,” Arevalo said. “I love this tournament. Since the first time I played here, I had a bond with the city. I’m just really happy that we were able to win this match because it was a real battle. Mate and I stuck together.”
Christian Harrison and Evan King
A partnership that did not exist at the beginning of this year became one of the most intriguing success stories. Christian Harrison and Evan King burst onto the scene with ATP 500 titles in Dallas and Acapulco, and added another trophy in Brussels, culminating in a Nitto ATP Finals berth – the first all-American duo to reach the season finale since Mike Bryan and Jack Sock won the title in 2018.
Harrison and King showed their mastery in all areas by winning two indoor hard court titles and reaching the semi-finals on the clay court of Roland Garros. They also reached the finals in Auckland and Delray Beach after making their team debut at the ATP Challenger Tour event in Quimper, France, in January.
