Defending Champions: Nikola Mektic and Rajeev Ram

The tournament will use a single-elimination format. Under ATP doubles rules, matches are played as two tiebreak sets with no-ad scoring. When the teams split the first two sets, a 10-point match tiebreak replaces a traditional third set. That shortened format creates additional volatility because one poor service game or a brief run in the match tiebreak can determine the result.

Defending Champions Return with Different Partners

Nikola Mektic and Rajeev Ram captured the 2025 Cincinnati Open championship together, but they will not defend their title as a team.

Ram reunites with Joe Salisbury, his longtime partner and the player with whom he won the 2022 Cincinnati championship. Their experience, communication and ability to perform under pressure immediately make them one of the tournament’s most dangerous teams.

Mektic will partner American Austin Krajicek. Mektic supplies elite hands, positioning and return instincts, while Krajicek gives the team a powerful left-handed serve and aggressive net presence.

The split creates one of the tournament’s most interesting storylines. Both defending champions have legitimate opportunities to win consecutive Cincinnati titles, but each must do so alongside a new partner.

Harri Heliovaara and Henry Patten Enter as the Favorites

Harri Heliovaara and Henry Patten enter Cincinnati as the world’s joint No. 1-ranked doubles players.

The Finnish-British partnership reached the top of the ATP doubles rankings in June after building one of the tour’s most consistent résumés. They won four titles during the early portion of the 2026 season, including the ATP Masters 1000 tournament in Madrid, and reached the Roland Garros final.

Heliovaara and Patten complement one another extremely well. Patten’s left-handed serve creates difficult return angles, while Heliovaara is an intelligent returner who reads opponents and controls the net. Their experience in deciding tiebreaks makes them particularly dangerous in Cincinnati’s shortened doubles format.

The biggest concern is the pressure that comes with being the top-ranked team. Every opponent will enter with an aggressive game plan and little to lose, especially in a format where one match tiebreak can produce an upset.

Granollers and Zeballos Remain Major Championship Threats

Marcel Granollers and Horacio Zeballos are among the most accomplished teams in the field. They won the Cincinnati Open in 2021 and enter the tournament ranked third and fourth, respectively, in the ATP doubles rankings.

Granollers and Zeballos defeated Heliovaara and Patten in the 2026 Roland Garros final, giving them a significant recent victory over the tournament favorites. Their ability to absorb pace, extend rallies and change formations makes them difficult to attack.

Their familiarity with each other is another major advantage. While several Cincinnati entrants are new or temporary partnerships, Granollers and Zeballos have years of experience navigating important points together.

Arevalo and Pavic Attempt to Recapture the Rookwood Cup

Marcelo Arevalo and Mate Pavic return as one of three former Cincinnati championship teams in the field. They won the tournament in 2024 and remain one of the most balanced partnerships in men’s doubles.

Pavic’s left-handed serve and court coverage combine with Arevalo’s returning, movement and ability to finish points at the net. Both players are currently ranked inside the ATP doubles Top 15, providing them with the experience and seeding necessary to make another deep run.

Arevalo and Pavic may not enter as the outright favorites, but their previous success in Mason makes them one of the safest teams to consider in advancement markets.

Cash and Glasspool Lead Strong British Contingent

Julian Cash and Lloyd Glasspool enter Cincinnati tied at No. 6 in the ATP doubles rankings. Their serving ability and quick reactions at the net make them one of the most difficult teams to break on hard courts.

Joe Salisbury gives Great Britain another leading contender through his reunion with Rajeev Ram, while Henry Patten enters alongside Heliovaara as one-half of the top-ranked team.

The British players in the field bring a combination of serving strength, doubles specialization and championship experience. Cash and Glasspool may offer the best betting value of the group because they are likely to be priced behind the more recognizable championship teams.

Bolelli, Vavassori, Krawietz and Puetz Add Depth

Simone Bolelli and Andrea Vavassori form another established partnership capable of winning the tournament. Vavassori and Bolelli are ranked eighth and ninth, respectively, giving them one of the strongest combined rankings in the field.

Kevin Krawietz and Tim Puetz provide Germany with another championship-level team. Both are ranked inside the ATP doubles Top 11 and have the serving, returning and tactical discipline needed to survive close matches.

Neither partnership should be overlooked. The deciding match-tiebreak format frequently rewards established teams that communicate effectively and remain composed after losing a set.

ATP Singles Stars Enter the Doubles Draw

Several notable singles players will compete in doubles as part of their US Open preparation.

Daniil Medvedev will partner American rising star Learner Tien. Karen Khachanov and Andrey Rublev reunite as an all-Russian pairing, while Alexander Zverev will play with veteran Marcelo Melo.

Lorenzo Musetti teams with Matteo Arnaldi, Casper Ruud partners Andre Goransson and Americans Tommy Paul and Ethan Quinn will compete together. Arthur Rinderknech and Valentin Vacherot also enter as a family partnership between cousins.

These teams are difficult to evaluate. Singles players can bring superior serving, returning and baseline power, but established doubles teams generally possess better positioning and communication.

The most dangerous singles-based team could be Khachanov and Rublev. Both have powerful groundstrokes and significant experience playing together. Zverev and Melo also offer an intriguing combination of one of the world’s best servers and one of the most experienced doubles players in the draw.

Marcel Granollers/Horacio Zeballos+450

Julian Cash/Lloyd Glasspool+600

Simone Bolelli/Andrea Vavassori+700

Karen Khachanov/Andrey Rublev+2200

Alexander Zverev/Marcelo Melo+2800

The official draw will have a major influence on the market. Established teams placed away from Heliovaara and Patten or Granollers and Zeballos could see their championship prices shorten significantly.

Cincinnati Open ATP Doubles Prediction

Predicted Champions: Harri Heliovaara and Henry Patten

Heliovaara and Patten are the most complete team in the field. They enter as the joint world No. 1s, have already won an ATP Masters 1000 championship during the 2026 season and possess the left-handed/right-handed combination needed to create uncomfortable serving and returning patterns.

Granollers and Zeballos present the biggest threat because of their experience, current rankings and recent victory over Heliovaara and Patten at Roland Garros.

Cash and Glasspool are the strongest dark-horse selection among the highly ranked teams, while Ram and Salisbury offer the most appealing longshot based on championship history.

Projected Final: Heliovaara/Patten over Granollers/Zeballos

Best Longshot: Ram/Salisbury

Best Singles-Based Team: Khachanov/Rublev

Potential Surprise Team: Mektic/Krajicek

Best Bet: Heliovaara and Patten to Win the Tournament

Projected Odds: +350

Heliovaara and Patten deserve to be the favorites because of their ranking, partnership continuity and 2026 results. They have demonstrated that they can win Masters 1000 tournaments and consistently reach the closing rounds of major events.

Their serving combination should be especially effective on Cincinnati’s outdoor hard courts. Patten’s left-handed delivery can pull returners away from the court, allowing Heliovaara to attack the first volley.

The price is playable at +350 or better. Anything shorter than +300 would create enough concern to consider Granollers and Zeballos or another contender at a larger number.

Prop Bet #1: Arevalo and Pavic to Reach the Final

Projected Odds: +250

Arevalo and Pavic have already proven that they can succeed in Cincinnati, winning the championship in 2024.

Their combination of experience, left-handed serving and aggressive net play makes them difficult to defeat in a shortened format. They also enter with more partnership continuity than many of the teams featuring singles players or new pairings.

This wager becomes most attractive if Arevalo and Pavic are placed outside the same half as Heliovaara and Patten. Look for +250 or better before making the wager.

Prop Bet #2: Ram and Salisbury to Reach the Semifinals

Projected Odds: +200

Ram and Salisbury reunite at a tournament where they won the championship together in 2022.

Their familiarity should allow them to avoid many of the communication problems that affect newly formed teams. Ram also won Cincinnati in 2025 with Mektic, giving him consecutive seasons of outstanding results at the tournament.

Age and recent partnership changes create some uncertainty, but their experience in major matches makes a semifinal appearance more appealing than asking them to win the entire tournament.

The prop offers value at +200 or better, particularly if they avoid one of the top two projected teams before the semifinals.

Prop Bet #3: Mektic and Krajicek to Reach the Quarterfinals

Projected Odds: -135

Mektic and Krajicek may need time to develop chemistry, but their individual doubles skills should be enough to win at least two matches.

Mektic is the defending Cincinnati champion, while Krajicek provides a powerful left-handed serve and the ability to control the front of the court. Their complementary styles give them a higher floor than most newly created partnerships.

A difficult opening-round opponent could reduce the value, so bettors should confirm the draw before placing the wager. The recommendation remains playable at -140 or better.

Prop Bet #4: Medvedev and Tien to Win Their First Match

Projected Odds: +110

Medvedev and Tien are unlikely to possess the positioning or partnership experience of the leading doubles teams, but both are outstanding returners capable of immediately placing pressure on opposing servers.

Medvedev’s court coverage and Tien’s ability to redirect pace could make them uncomfortable opponents, especially against another newly formed partnership.

This bet is heavily dependent on the draw. It should be avoided if they face one of the established seeded teams in the opening round. Against another singles-based team or an on-site entry, +110 or better would provide reasonable value.

Cincinnati Open ATP Doubles Betting Summary

The safest championship selection is Heliovaara and Patten, although the projected +350 price should not be accepted until the draw is reviewed.

Arevalo and Pavic offer strong advancement value because of their previous Cincinnati championship, while Ram and Salisbury are the most attractive longshot among the established doubles partnerships.

Mektic and Krajicek provide a more conservative quarterfinal selection. Medvedev and Tien are the most interesting first-round underdog, but their value will depend entirely on the opponent.

Best Bet: Heliovaara/Patten to win the tournament

Best Prop Bet: Ram/Salisbury to reach the semifinals

Best Advancement Bet: Mektic/Krajicek to reach the quarterfinals

Best Longshot: Ram/Salisbury to win the tournament

Best First-Round Underdog: Medvedev/Tien

Predicted Final: Heliovaara/Patten defeat Granollers/Zeballos

Final Outlook

The 2026 Cincinnati Open ATP doubles field features nearly every type of championship contender.

Heliovaara and Patten enter with the world No. 1 ranking and the strongest recent résumé. Granollers and Zeballos possess the experience and current form needed to defeat them, while Cash and Glasspool, Bolelli and Vavassori, and Krawietz and Puetz give the tournament tremendous depth.

Former Cincinnati champions Arevalo and Pavic, Ram and Salisbury, and Granollers and Zeballos know how to manage the conditions in Mason. Mektic also returns attempting to defend his title with a new partner.

The teams featuring singles stars add unpredictability and name recognition. Khachanov and Rublev, Zverev and Melo, Medvedev and Tien, and Paul and Quinn all possess enough talent to eliminate a seeded team.

Because of no-ad scoring and the deciding 10-point match tiebreak, the difference between a championship run and a first-round loss can be only a handful of points. Heliovaara and Patten deserve to enter as the favorites, but Cincinnati’s deep field and volatile format should produce close matches and several legitimate upset opportunities.
