My pick: Matteo Arnaldi to advance · locked 2026-08-28 04:05 UTC

Prediction

Arnaldi, though his seeding is writing checks his season hasn't cashed. The Italian wears 30 next to his name off last year's rankings work; his 2026 is 13–17, and his hard-court career sits at a flat 57–58. What saves the pick: Duckworth at 34 is having the same kind of season (13–19) with less upside attached, Arnaldi's 2023 fourth round here proves the ceiling on this exact stage, and the Australian's flat, serve-reliant game gives the younger man rhythm rather than problems. First meeting. If Duckworth's serve rides a hot day this drags long; the more likely story is Arnaldi's superior movement compounding across three-plus hours. Four sets, untidy ones.

The case for Matteo Arnaldi

62% to win

Arnaldi's fourth round here in 2023 — beating seeded opposition along the way — is the best result either man has produced at this tournament, and at 25 his athleticism gives him the highest ceiling on the court. A 13–17 season lowers expectations, not ability; seeds with nothing going are dangerous precisely because the first win resets everything.

The case for James Duckworth

38% to win

Duckworth is the sort of pro who makes .500 seeds regret their year: a flat, attacking game, 116 career hard-court wins, and no respect whatsoever for reputations. Arnaldi's season is as beatable as his — and the Australian has been playing best-of-five since before the Italian owned a ranking.

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

  • Arnaldi's 2023 fourth round here — his breakout — is the résumé behind a 30th seeding his 13–17 season hasn't matched.
  • Duckworth, 34, is one of the draw's several thirty-something Australians; his best US Open remains a 2022 second round.
  • First meeting — and the section's prize is real: the winner is two rounds from the quarter housing defending champion Alcaraz.

Head to head

Never met. Arnaldi's rise came as Duckworth's generation began leaving the stage — the Australian's flat pace against the Italian's legs is a fresh question.

Watch: Opening-round coverage starts Sunday at 11 a.m. ET across ESPN, ESPN2 and ABC, with ESPN Deportes in Spanish — and every court streams in the ESPN app, including a whip-around channel for the early rounds. (ESPN press-room release and listings, as of 2026-08-27)

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 among the draw's honest laborers: a seed at 13–17 defending his number against a 34-year-old at 13–19 defending his relevance. The geography gives it stakes — this section sits in the defending champion's quarter, and every round survived is a round closer to the Alcaraz weather system. Arnaldi has been deep here before; Duckworth is running out of Augusts. Sunday through Tuesday; the loser takes home $140,000.
