CINCINNATI – Rajeev Ram did not have to call Joe Salisbury. He had just won Cincinnati with someone else.
Last August, Ram took the Western and Southern Open men’s doubles title alongside Nikola Mektic – his third career win at Lindner Family Tennis Center, and the first with a different partner. By the ordinary logic of a tour partnership that works, the combination should have continued. It did not. When the Cincinnati Open released its full 2026 doubles field on Thursday, Ram’s name appeared alongside Salisbury’s, the British player with whom he won the Cincinnati title four years ago. Mektic also entered – partnering Austin Krajicek, also pursuing back-to-back titles, from the other side of a reshuffled draw.
The pattern runs through both draws. All four reigning Cincinnati Open doubles champions are back for 2026. Not one of them returned with the same partner who helped them win.
The tournament confirmed the full 32-team men’s and women’s doubles fields Thursday, a lineup that includes 19 past Cincinnati champions across both draws, the world No. 1 ranked teams in both competitions, and a collection of singles players who have determined that August in Ohio is no longer optional preparation before the US Open begins August 30 at Flushing Meadows.
The most consequential entry in the men’s field may not belong to any defending champion. Harri Heliovaara and Henry Patten enter Cincinnati as the top-ranked doubles pair in the world, carrying form that has made them the sport’s dominant team across three Grand Slam cycles. In July, they beat Marcelo Arevalo and Mate Pavic 7-6(4), 7-6(3) to win Wimbledon, their third Grand Slam title and second All England Club championship in three years. After the Wimbledon final, Patten delivered a line that is not the product of press conference habit. “I owe Harri my career,” he told Sky Sports. “When I started with Harri, he took a chance on me. It might be the best decision he’s ever made.” Heliovaara was quieter: “To do it twice, I need to thank Henry for being the best partner in the world.”
They enter Cincinnati as the team every other pairing in the men’s draw must eventually account for.
The rest of that draw is not short on credentials. Arevalo and Pavic – the Wimbledon runners-up who took Heliovaara and Patten to tiebreakers in both sets – are also entered. Granollers and Zeballos, part of a Cincinnati men’s draw that already features Novak Djokovic, Jannik Sinner, and Alexander Zverev in singles, won the doubles title here in 2021 and carry the kind of accumulated hardcourt chemistry that seedings rarely reflect accurately. Bolelli and Vavassori, who reached the Roland Garros doubles final in June, and Julian Cash alongside Lloyd Glasspool add depth that makes a 32-team bracket unpredictable well past the first week.
Then there are the singles players. Daniil Medvedev has entered alongside American Learner Tien, a pairing that puts Medvedev’s relentless flat baseline game into a format that genuinely rewards it. Karen Khachanov and Andrey Rublev have combined – two of Russia’s most decorated players finding a doubles lane together ahead of the US Open. Zverev enters with Marcelo Melo, Casper Ruud alongside Andre Goransson, Tommy Paul with Ethan Quinn, Lorenzo Musetti with Matteo Arnaldi. The list of singles names entering Cincinnati doubles has expanded to the point where it looks less like scheduling convenience and more like a statement about what this tournament has become on the hardcourt calendar.
The women’s draw puts Erin Routliffe at its center, even if the seedings do not reflect that plainly. Routliffe won the title here last year with Gabriela Dabrowski. Dabrowski enters 2026 with Luisa Stefani – a different partner, the same ambition. The two Cincinnati champions are now positioned on opposite sides of a draw that may well bring them back together in the latter stages. Routliffe partners Aldila Sutjiadi and pursues a fourth Cincinnati women’s doubles title.
Standing between Routliffe and that fourth title is Katerina Siniakova and Taylor Townsend, the top-ranked women’s doubles team in the world and 2023 Cincinnati doubles champions. Siniakova’s doubles record tends to get underplayed against her singles results: multiple Grand Slam titles, a consistent presence at the top of the rankings, and the tactical range that gives Townsend space to apply net pressure with consistency. They are the team Routliffe needs to move past to reach four titles at Lindner Family Tennis Center. What the draw order will look like – whether those two pairings land in the same half or opposite quarters – has not yet been released, which is the one detail Thursday’s announcement left unresolved.
The women’s field carries its own layer of history. Jelena Ostapenko, the 2022 Cincinnati doubles champion, partners with Hsieh Su-Wei, who won the title here in 2013 – a span of 13 years the Taiwanese veteran has arrived ready to reduce. Leylah Fernandez and Sara Errani enter together, with Errani’s Paris Olympic gold medal in women’s doubles giving the Italian a credential that the entry list alone does not capture. Zhang Shuai and Xinyu Jiang, Cincinnati champions in 2021, complete a women’s draw that arrives at the peak of the US Open doubles season, with both draws carrying a field quality that the Cincinnati Open has not always been able to guarantee.
Across both draws, the 19 past Cincinnati champions confirmed Thursday represent the kind of competitive concentration that tournament directors spend years assembling. What makes it unusual this time is not the quantity of title experience but the absence of any partnership defending what it actually won. Every one of last year’s champions is back. None of them are back together.
The bracket draws, which will determine whether reshuffled partnerships meet each other early or stay on opposite sides of the field, have not been released. Whether Ram and Salisbury – who have spent four years accumulating results in different directions since their 2022 Cincinnati title – can rebuild the understanding that produced a championship here before is a question that their entry on Thursday could only raise. The matches in Ohio beginning August 11 will have to answer it.
The Western and Southern Open runs August 8 through 23. Doubles finals are scheduled for August 22 and 23.
