Cincinnati Open Tennis Picks: Upset Alert
Xinyu Wang (+330) vs. Coco Gauff
Gauff's just 2-3 since winning the French Open, and that run of bad form started with a 6-3, 6-3 loss to Wang on grass in Berlin. Gauff made only 41 percent of first serves in that match and Wang managed to consistently get on the front foot by attacking Gauff's vulnerable second serves. As good a defender as Gauff is, it's tough to consistently counterpunch in fast conditions, and a similar scenario could play out in this rematch given that Gauff's serving struggles have only gotten worse in recent tournaments.
Adam Walton (+400) vs. Daniil Medvedev
Medvedev has been extremely upset-prone all year, with five losses to players ranked outside the top 80 and 10 losses to opponents outside the top 40 among his 16 defeats in 2025. Walton plays his best tennis on hard courts, having won a Challenger level event on the surface this year and made a Masters 1000 fourth round in Miami. If the 85th-ranked Aussie catches the temperamental Medvedev on a bad day, Walton could add to the 15th-ranked Russian's lengthy list of bad losses in 2025.
Honorable Mention
Luca Nardi (+310) vs. Denis Shapovalov
Cincinnati Open Tennis Odds: Lock It In
Karen Khachanov (-300) vs. Valentin Royer
Khachanov has made at least the quarterfinals in each of his last four tournaments, including a quarterfinal showing at Wimbledon and a runner-up finish at the Canadian Open to propel him to No. 12 in the rankings. The Russian should keep rolling here against the 104th-ranked Royer, whose first-round win over Sebastian Ofner marked only the second ATP Tour-level win for the 24-year-old Frenchman.
Brandon Nakashima (-330) vs. Alexander Blockx
Nakashima wins the matches he should on hard courts, with a 10-5 record in his last 15 matches on this surface and all five losses coming against top-25 opponents. The 31st-ranked American takes care of his serve well and has been at his best in fast conditions like the ones in Cincinnati. Blockx upset Nakashima's 61st-ranked compatriot Marcos Giron in the first round for the 119th-ranked Belgian's first ATP Tour-level win, but Nakashima's a far tougher opponent with significantly more weapons.
Honorable Mention
Alexei Popyrin (-300) vs. Martin Landaluce
Cincinnati Open Tennis Predictions: Value Bets
Linda Noskova (-150) vs. Iva Jovic
Noskova has had a strong season to climb to No. 23 in the rankings, and the 20-year-old Czech is at her best controlling play with her powerful groundstrokes on hard courts. Jovic is another player with a bright future, but the 17-year-old American is a step behind Noskova in her development, currently sitting at No. 88. Jovic has shown a strong all-court game, but Noskova's edge in power will likely prove to be the difference here.
Caty McNally (-115) vs. McCartney Kessler
McNally has a true home-court advantage in this battle between Americans as a Cincinnati native. She's ranked No. 104 but has been significantly outplaying that ranking recently. After being the only player to take a set off Iga Swiatek at Wimbledon, McNally has gone on a 13-1 run, winning a WTA 125 level tournament and an ITF event before falling in a tight three-setter to sixth-ranked Madison Keys in the third round of the Canadian Open. Kessler barely made it into the seeded range here at No. 29, and she's just 2-3 in her last five matches.
Honorable Mention
Cameron Norrie (-150) vs. Roberto Bautista Agut
