My pick: Arthur Rinderknech to advance · locked 2026-08-28 03:15 UTCPrediction
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, quoted to a decimal because false precision is funnier — and tennis has no draw to hide the rounding in.

The briefing
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.

Court & schedule: Not yet assigned — the US Open posts each day's order of play the evening before, so day-one courts land the night of 29 August. This one profiles as a field-court match. (US Open order-of-play release cadence, as of 2026-08-27)
Weather: The opening window looks kind: mostly sunny and 85–86°F Sunday and Monday, with thunderstorm chances only creeping in on Tuesday. Ashe and Armstrong close their roofs if the sky turns; the field courts wait it out. (National Weather Service New York forecast, as of 2026-08-27)
Venue: USTA Billie Jean King National Tennis Center, Flushing Meadows, New York — hard.
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.
