The world’s No. 1 ranked players, Aryna Sabalenka and Jannik Sinner, headline the entries as they both come back to defend their titles. They will be joined by six other Cincinnati Open champions in the field, led by three-time winner Novak Djokovic (2023, 2020, 2018) as well as Coco Gauff (2023), Madison Keys (2019), Alexander Zverev (2021), Daniil Medvedev (2019) and Grigor Dimitrov (2017).

Every player who has won a title this season is in the field, led by Carlos Alcaraz who has already claimed five. The 2024 Cincinnati Open finalists Sabalenka and Jessica Pegula are tied for the most WTA titles this season with three apiece. Those champions also include the winners of this year’s other 1000-level tournaments, where Alcaraz, Sabalenka and 18-year-old Mirra Andreeva have won two apiece with the other titles being collected by Amanda Anisimova, Jasmine Paolini, Jack Draper, Jakub Mensik and Casper Ruud.

“We look forward to welcoming the world’s best tennis stars to compete for the Cincinnati Open title in August,” said Tournament Director Bob Moran. “We have received a lot of excitement from the players about coming back to see our transformed campus and experiencing the new player amenities. Players and fans alike will enjoy the re-imagined venue and world-class atmosphere as the sport’s best compete for the title.”

There will be 96 players in each singles field this year, up from 56 in 2024. The initial entrants include:

• Players representing 37 nations. The United States has the largest contingent in the field with 24 players, including six who are in the Top 10 of their tour’s rankings: No. 2 Coco Gauff, No. 3 Jessica Pegula, No. 8 Madison Keys, No. 10 Emma Navarro, No. 5 Taylor Fritz and No. 10 Ben Shelton.
• Forty-nine players who have won a title this year are entered, and collectively they have won all 65 of this season’s tournaments.
• A total of 119 players who have won a title during their career, combining for 746 trophies. Novak Djokovic has the most with 100. Six other players have claimed 20 or more: Petra Kvitova, 31; Alexander Zverev, 24; Iga Swiatek, 22; Carlos Alcaraz, 21; Aryna Sabalenka, 20; Daniil Medvedev, 20.
• Sixteen players with college tennis experience, including former University of Kentucky standout Gabriel Diallo, who won his first career ATP Tour title last month, and Mason native Peyton Stearns, who won NCAA singles and team titles for the University of Texas.

Former Cincinnati Open finalist and two-time Wimbledon champion Petra Kvitova is one of nine players to enter using a protected ranking following an extended layoff. The others are Nick Kyrgios, Jenson Brooksby, Sebastian Ofner, Bianca Andreescu, Sorana Cirstea, Marketa Vondrousova, Zhu Lin and Anastajia Sevastova.

Twelve players will be added to each field through a two-round qualifying event that will take place Aug. 5-6. Additional players will be awarded wild cards.

The campus transformation that has added 10 courts this year to make it possible to expand the event is part of a $260 million investment with the City of Mason, Warren County and the State of Ohio. It will bring the total number of outdoor courts at the venue to 31 while also adding a six-court indoor facility, pickleball and padel courts, new locker room facilities for professional and recreational player use, and a Clubhouse that will be utilized year-round with restaurant and function room space.
