Arnaldi is the better all-court player and the one with the stronger recent top-level results. His 2026 clay-season peak included a Roland Garros semifinal run, which is a meaningful sign that his level can hold up in major-pressure matches. Even though this is a hard-court match, that run reinforces that he is entering the final Slam of the season with far more proven ATP-level output than Duckworth, whose best results tend to come when he can control the first strike and avoid extended return battles. On a faster surface, Duckworth’s serve gives him a path to compete, but it also puts more pressure on him to be efficient in return games, which is not where he usually has the edge against a player of Arnaldi’s level. The market is slightly inflated on Duckworth because underdogs with a dependable serve often attract support at the US Open, where match length and tiebreak chances can create upset hope. Even so, Arnaldi’s baseline quality and recent major form make him the more likely winner, and the current moneyline still sits below what a fair closing range should be if the market tightens toward the more reliable ATP ranking and form profile. The better angle is Arnaldi outright rather than forcing a heavier handicap, since Duckworth’s serve can keep one or two sets closer than the matchup suggests.
Arnaldi comes in with the stronger recent body of work. His 2026 season featured a sharp rebound after a difficult start, and his Roland Garros semifinal appearance was the clearest sign that his level has risen well above a typical fringe-top-50 player. That matters at a Slam, where his ability to absorb pace from the baseline and extend rallies can wear down opponents who rely more on serve-first patterns. He is also the player more likely to convert a higher share of return chances if Duckworth’s first serve dips. Duckworth is the more serve-dependent player and the one who needs a clean, high-hold match to keep this close. His ATP bio and profile show a career built around serve production and hard-court experience, but his recent tour-level ceiling is lower than Arnaldi’s. The matchup points toward Arnaldi controlling more return games and having the better chance to win from the baseline, while Duckworth’s best route is to stretch sets and hope the scoreboard stays tight enough to protect the spread.
Matteo Arnaldi is the projected winner, and the matchup points to a four-set result rather than a quick rout. Duckworth’s serve can keep parts of the match close, but Arnaldi’s stronger baseline game and better recent major form should decide it over time. The best projection is Arnaldi in four sets with about 38 total games, which fits the moneyline edge without overcommitting to a blowout spread.
