James Duckworth turns a retirement scare into a US Open second-round launchpad

James Duckworth ’s 5-7, 6-3, 6-2, 7-6(8) win over No.30 seed Matteo Arnaldi was less about the upset label than the tactical adjustment that made it possible. Two days after retiring in Winston-Salem, the Australian absorbed the Italian’s early pressure, then changed the geometry of the match.

Duckworth had to win the match twice James Duckworth began his US Open campaign on August 31, 2026, with the obvious question hanging over him: could his body hold up after retiring against Arthur Fery in the Winston-Salem semi-finals two days earlier? The answer was not simply that he completed the match. He completed it while improving as the contest lengthened, beating Matteo Arnaldi 5-7, 6-3, 6-2, 7-6(8) to reach the second round. The result was confirmed by the US Open draw and Australian reporting, with Duckworth listed as the winner over the No.30 seed. (tennis.com)

The first set still belonged to Arnaldi. The Italian’s 70 per cent first-serve rate and ability to extend exchanges through the middle of the court gave him enough control to take Duckworth away from his preferred first-strike patterns. Duckworth was not getting enough cheap damage from his serve or first ball, and Arnaldi converted the opening phase into a one-set lead.

The adjustment was clear in the numbers Duckworth’s response was to make the match more serve-led and more uncomfortable on second-serve points. He struck 16 aces to Arnaldi’s five, won 55 per cent of his second-serve points compared with Arnaldi’s 42 per cent, and held 17 of 21 service games. Those figures point to a precise shift: Duckworth was not trying to out-rally Arnaldi for three or four extra shots. He was using the serve to start points on his terms, then looking to finish before Arnaldi could settle into his defensive patterns. (tennis.com)

The return was just as important. Duckworth won 58 per cent of Arnaldi’s second-serve points and broke in six of 20 return games. That is where the match moved decisively. Arnaldi’s first serve remained reliable, but once Duckworth got a look at the second delivery he attacked with enough depth and pace to prevent the Italian from building his preferred counterpunching sequence. The Australian’s best tennis came when he made Arnaldi defend immediately rather than allowing him to redirect the rally.

The fourth-set tiebreak tested the comeback The danger was that Duckworth’s control through the second and third sets would disappear once Arnaldi found a way back into the fourth. It nearly did. Arnaldi saved 13 of 19 break points across the match, and the final set became a contest of short margins rather than sustained dominance. Duckworth still created the better pressure profile, saving 11 of 15 break points, but he needed the deciding-set tiebreak to finish the job. (tennis.com)

Winning that tiebreak 10-8 matters because it closes the loop on the Winston-Salem concern. Duckworth retired from his semi-final against Fery at 6-4, 1-2, with the tournament’s official results recording the retirement. There is no verified public detail in the available sources identifying the nature or severity of the issue, so the responsible conclusion is narrower: he recovered sufficiently to play and win a near-three-and-a-half-hour Grand Slam match, without treating that as proof the problem has disappeared.

Wu offers a different second-round problem Duckworth’s next opponent is Yibing Wu, with the second-round match scheduled for September 2. Wu represents a different tactical assignment from Arnaldi: less emphasis on absorbing a long, varied exchange and more on surviving another aggressive, first-strike player. Duckworth will need the same quality of first serve, but his return position and tolerance for short rallies could become more decisive if Wu keeps points compressed. (tennis.com)

The broader development is not that Duckworth has suddenly become a deep-Slam favourite. It is that his current hard-court level has become credible across consecutive weeks. He reached the Winston-Salem quarter-finals before the semi-final retirement, then backed that run with a ranked-seed win in New York. After a first set in which Arnaldi controlled the shape of the contest, Duckworth imposed his own: serve bigger, attack second serves, and refuse to let the match drift into a baseline referendum. The next test is whether that formula can survive another opponent who is comfortable playing on the front foot.
