The Cincinnati Open will field 24 Americans across its two singles draws next week, the largest home contingent of the North American hard-court swing, and for most of them it is the last chance to change where they land in the US Open draw. Seeding at Flushing Meadows is set on the rankings published August 24, the day after the Cincinnati finals.
That makes Mason the final event capable of moving a player across the lines that decide a fortnight: the top 32 that guarantees a seeding at all, and the top 16 and top eight cutoffs that determine how far into the draw a player can go before meeting a title favorite. Winston-Salem and Cleveland follow, but for anyone in this field the ranking is effectively settled when the Cincinnati finals end.
The men are led by Taylor Fritz and Ben Shelton, both inside the top 10 and now separated by the narrowest margin of the season after Fritz took over as the top-ranked American this week. Tommy Paul, Frances Tiafoe and Learner Tien fill out a group with genuine seeding stakes rather than ceremonial ones, and several of them are defending points from last summer that will disappear whatever happens in Ohio.
On the women’s side Coco Gauff, Jessica Pegula and Amanda Anisimova all entered from inside the WTA top 10, and Madison Keys returns as the 2019 champion. Gauff won the title in 2023 and Pegula reached the final in 2024, which means three of the last four women’s finals in Mason have featured an American.
The tournament’s own invitations tell the same story. Five of the seven women’s main-draw wild cards went to Americans: Venus Williams, Sloane Stephens, Taylor Townsend, Caroline Dolehide and Elvina Kalieva. The remaining two went to Darja Vidmanova of the Czech Republic and Lois Boisson of France. On the men’s side the wild cards went the other way entirely, to Stan Wawrinka, Gael Monfils, Grigor Dimitrov and Jack Draper, three of whom are in the closing stretch of long careers.
Williams, 46, holds a 12-10 record at the tournament and reached the semifinals in 2012. She has also been given a doubles wild card alongside Serena Williams, the pair playing this event together for the first time. Stephens, a semifinalist here in 2013, returns for the first time since 2023. Townsend heads the doubles field as one half of the world’s top-ranked team with Katerina Siniakova.
The depth continues below the main draw. Twelve Americans lead the qualifying field, more than any other nation, across two 48-player draws that will send 12 men and 12 women through on August 11 and 12. Robin Montgomery, who won her first tour title in June, received a qualifying wild card.
There is a structural quirk worth understanding for the players at the bottom of that group. None of what happens in Mason counts toward the US Open Wild Card Challenge, the race that hands main-draw places to the leading American finishers. Cincinnati results are excluded for both the men and the women even though the event falls inside the qualifying window.
It is the largest hard-court tournament in that window and carries the most ranking points, and for the Challenge none of it registers. An American who receives a Cincinnati wild card gains a valuable week for her ranking and nothing at all for that race. The draw itself has opened up. Carlos Alcaraz withdrew with a wrist injury and will not defend the title he won last year, removing the man who has taken two of the last three US Opens from the tune-up entirely. Iga Swiatek remains as the women’s defending champion.
What that leaves is a familiar late-summer equation for the American players, and a slightly cruel one. The points are there and the opposition is thinner than usual. So is the margin. Two weeks of heat and humidity in Ohio have historically sent as many players to New York compromised as confident, and the seeding gained in Mason is worth little to anyone who arrives at Flushing Meadows unable to use it.
