Final · Sunday, August 30, 2026 · Round of 128
Result
Shimabukuro took the opening tiebreak and then spent three hours watching the 26th seed's second serve win the match. Rinderknech won 69% of those points to Shimabukuro's 47%, broke five times from thirteen chances while conceding one, and took the third set in a tiebreak before closing out 6-2. Nine double faults on the other side of the net did not help. Coverage of this one did not go much past the scoreline; the box score is most of what there is.

At this Stage
Round of 128, seeding versus season: Rinderknech's 26 rests on last year's New York fourth round and a Shanghai final, while his 2026 ledger runs two games under water. That is the profile upsets are made of — except his opponent is chasing a first US Open win of any kind. The winner gets Munar or Atmane in a Round of 64 that extends this section's no-heavyweights run one more round. Sunday through Tuesday; the forecast mostly cooperates.
What we know now
What I said beforehand
The preview, frozen before the first serve. Clearly dated, never rewritten — that's the deal that makes the pick worth anything.
Rinderknech. The 26th seed's ranking is built on real material — a fourth round here last year, a Masters final in Shanghai the autumn before, and the kind of serve that keeps hard-court matches on his terms. His 2026 has drifted (17–19), which is why the seed number flatters the current form; but Shimabukuro's case as beneficiary is thin. The Japanese No. 87 is having a solid year by his standards (17–15) with a career built at challenger level, a 29–33 hard-court record, and no previous US Open win. First meeting. Rinderknech's serve — launched from 6′5″ against an opponent five inches shorter — is the simplest kind of mismatch on a quick court: fewer rallies, fewer chances. Four sets at most.
The case for Arthur Rinderknech
74% to winRinderknech's floor at this tournament is the fourth round he reached twelve months ago, and his serve is the kind of shot that ends debates about form. He beat top-tier opposition throughout his 2025 Shanghai final run, his height advantage converts directly to free points here, and a first-time US Open opponent has never returned anything like this.
The case for Sho Shimabukuro
26% to winShimabukuro arrives with the better season and none of the pressure: Rinderknech is the one defending fourth-round points from a year that has since gone sideways. The Japanese game plan writes itself — return deep, make the big man play defense, and trust that a 17–19 seed gives you a loose service game per set. His 17 wins this year say he takes those when offered.
Both cases written 2026-08-28, before the first ball — frozen into the record exactly as written, whatever the result. The percentages are mine — opinions with a percent sign on. They add to 100 because tennis has no draw to hide the rounding in.

Storylines
- Rinderknech's fourth round here last year and his 2025 Shanghai Masters final are the résumé behind the 26th seeding — his 2026 form (17–19) is the argument against it.
- Shimabukuro is chasing his first US Open main-draw win; his only previous appearance ended in the 2023 first round.
- First meeting — and a five-inch height gap (6′5″ to 6′0″) that frames the whole contest: serve against return, repeated for up to five sets.
Head to head
Never met. Rinderknech's tour calendar and Shimabukuro's challenger-circuit one have finally intersected at the major both would pick for it.

Weather: Sunday — the men's final, and the last match of the fortnight — was forecast at 78°F with showers and thunderstorms 95% likely, the wettest day of the two weeks and the one day that could not be pushed back. The rain came in the morning and stopped before the final, which Ashe played with its roof open. It cleared from there: 15% overnight, 15% Monday, then dry and sunny.
