Frances Tiafoe, the No. 11 seed ranked No. 12, faces fellow American Martin Damm, ranked No. 90, in a first-round US Open matchup on hard courts at Louis Armstrong Stadium. Tiafoe enters with strong recent form after reaching the Cincinnati final and maintains an excellent Grand Slam record at Flushing Meadows, where he has advanced deep multiple times. Damm, a 22-year-old left-hander standing 6'8", arrives with momentum from a career-highlight upset of Daniil Medvedev at Winston-Salem that lifted him to a new ranking high. The pair met in last year’s US Open second round, with Tiafoe prevailing in four sets. Damm’s big serve and recent confidence provide upset potential against the more experienced, athletic favorite in this best-of-five encounter.
