Final · Monday, August 31, 2026 · Round of 128
Result
The 30th seed took the first set and then spent three hours losing the match at the net: Duckworth came forward 48 times and won 31 of those points, hit 16 aces to Arnaldi's five, and broke six times from 19 chances against Arnaldi's four from 15. The fourth set went to a tiebreak Duckworth took 10-8, on 142 points to 131 across 3 hours 25 minutes. Almost nothing was written about this one beyond a live blog that stopped logging after the third set; the box score is most of what exists.

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.
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.
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 winArnaldi'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 winDuckworth 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 — opinions with a percent sign on. They add to 100 because tennis has no draw to hide the rounding in.
My locked pick: Matteo Arnaldi to advance ✗ WRONG
“The younger legs, the 2023 fourth round here, and an opponent whose season is just as flawed with less ceiling above it.”

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.
