Frances Tiafoe opened the 2026 U.S. Open on Monday night against Martin Damm Jr., restarting a matchup that already belonged to the tournament’s recent history. The No. 11-ranked player was back across the net from Damm at the USTA Billie Jean King National Tennis Center, where the pair met for the second straight year.
That is why search interest around Martin Damm Jr. is spiking now: he was the opponent in a first-round rematch, and Tiafoe was trying to reset after being bounced in the third round of the 2025 U.S. Open. Tiafoe had reached at least the quarterfinals in three straight years before that slip, so the opening match carried more weight than a routine start. For Damm, it was only his fourth Grand Slam appearance, though he had already shown he could stay in the draw longer than expected by reaching the second round in his U.S. Open debut in 2025.
The previous meeting gives the rematch its edge. Tiafoe won that 2025 U.S. Open match in the Round of 64 in four sets, 6-4, 7-5, 6-7, 7-5, a scoreline that left little doubt the lower-ranked player could make him work for every hold. Damm’s recent results have been uneven — he reached the Round of 16 at the Winston-Salem Open but was bounced in qualifiers at the Cincinnati Masters — which helps explain why oddsmakers still made Tiafoe the favorite, even if the -382 line was shorter than the kind of number usually attached to a No. 11 seed in an opener like this.
The market was respecting Tiafoe’s standing, but not treating this as a locked result, and that gap is the real story around the matchup. Damm had already taken one step forward at the U.S. Open before, and Tiafoe entered knowing that a second straight year against the same opponent would not automatically produce the same level of control. The first-round meeting on Monday night was less about a routine favorite and more about whether the rematch could turn familiar into difficult.
What happens next is simple, even if the path is not: Tiafoe either reasserts the form that once carried him deep into the U.S. Open, or Damm turns a repeat pairing into the kind of upset that reshapes a draw before it has barely settled. The match result was not part of the setup, which is exactly why the rematch had enough room to matter.
