Frances Tiafoe begins the 2026 U.S. Open on Monday night against Martin Damm Jr. in a first-round rematch that already carries more context than a standard opener. Tiafoe is the No. 11-ranked player in the field, and he will again be expected to handle a matchup he narrowly survived last year.
The pair met at the 2025 U.S. Open in the Round of 64, where Tiafoe came through in four sets, 6-4, 7-5, 6-7, 7-5. That result mattered not only because it was close, but because it set up a tougher tournament story for both men at the USTA Billie Jean King National Tennis Center.
A rematch with recent history
For Tiafoe, this is a chance to make a cleaner start than he managed in 2025. After that win over Damm, he was bounced in the third round, ending three straight years of reaching at least the quarterfinals in New York. That kind of run builds expectation, which is why an opening match like this can feel more demanding than the draw suggests.
It is also a reminder that the U.S. Open can expose any lapse quickly. Tiafoe will start as a clear favorite — open as -382 to beat Martin Damm Jr. in the rematch — but the numbers do not remove the tension that comes with a player who pushed him hard once already.
What Martin Damm Jr. brings into the match
Damm is still early in his Grand Slam journey, but he is not arriving without recent match experience. The 22-year-old made the second round in his debut at the 2025 U.S. Open, and earlier in 2026 he reached the Round of 16 at the Winston-Salem Open before being bounced in qualifiers at the Cincinnati Masters.
That is a mixed but useful preparation line. He has shown he can handle the stage well enough to win matches at this level, and his first meeting with Tiafoe last year proved he is capable of making the favorite work deep into a contest.
Why Tiafoe still has to be sharp
The bigger question is not whether Tiafoe has the better resume. It is whether he can impose that status from the first ball and avoid a long, uncomfortable evening. A repeat of the 2025 pattern would keep Damm in the contest for much of the night, and that is exactly the sort of opening-round pressure Tiafoe will want to avoid.
He has the ranking, the experience and the edge from their previous meeting. But in a tournament where margins are often small, the first round still asks for focus, discipline and a quick sense of control.
That is why this rematch matters: Tiafoe is expected to win, but he also needs to show that the road in 2026 can begin with authority rather than another fight to survive.
