Damm Jr vs Tiafoe ATP Tennis Preview
Frances Tiafoe opens his US Open against Martin Damm Jr. as the stronger betting side, but this matchup has danger written all over Damm’s serve. Tiafoe leads the H2H 1-0 after winning their 2025 US Open meeting in four sets, despite Damm blasting 27 aces.
Tiafoe arrives as World No. 12 after a Cincinnati runner-up finish and owns two US Open semifinal runs. Damm, ranked No. 90, is a 6’8″ lefty whose power can shorten sets fast. Still, longer rallies favor Tiafoe’s movement and return game, making the American the cleaner betting profile.
