NEW YORK – Carlos Alcaraz is -421 on the moneyline for Tuesday night’s US Open quarterfinal against Ben Shelton, and the sharper number on the board is the set spread, where Alcaraz -1.5 sets pays -215 to close the match without dropping one.
The Number Worth Betting
Alcaraz is -421 to beat Shelton outright and Shelton is +317 to pull the upset, a gap that requires laying $421 to win $100 on the favorite. The set spread narrows that to -215 on Alcaraz taking it without dropping a set, the same lean at a price that pays nearly double the return for a result the history underneath it already supports.
| Market | Odds |
|---|---|
| Alcaraz moneyline | -421 |
| Shelton moneyline | +317 |
| Alcaraz -1.5 sets | -215 |
| Total games | 38.5 (Over -115 / Under -125) |
Alcaraz is 26-3 this season and has dropped just one set across four rounds at Flushing Meadows, in the second round against Jaime Faria. He swept Tommy Paul 6-4, 6-3, 6-4 in the round of 16. Three of Shelton’s four wins here ran four sets before he finally played a clean one, a 6-2, 6-3, 6-4 dismissal of Stefanos Tsitsipas in which he lost only 14 points on his own serve.
The straight-sets price bets that Alcaraz’s cleaner path holds up against a better opponent, not that Shelton collapses. The 38.5-game total leans the same way, but the set spread bets the outcome itself rather than how many games it takes to arrive. Alcaraz is the shortest price of Tuesday’s two men’s quarterfinals on the legal sports betting board.
Alcaraz’s First Five Months Back
A wrist injury stopped Alcaraz’s season in April and took the French Open, Wimbledon and both North American Masters stops off his calendar, making this tournament his first event back after five months away.
Alcaraz opened the tournament as the betting favorite in the US Open odds once Jannik Sinner withdrew with a knee injury, and nothing about the four rounds since has argued against that price. A player returning from a half-year absence and needing only one dropped set to reach a quarterfinal is the kind of form that keeps a heavy favorite’s number where it is instead of inviting bettors to fade it.
Shelton’s Bumpy Path Here
Shelton is 0-3 against Alcaraz, and the closest he has come was a 2025 French Open fourth-round loss in which he held three set points in the opening tiebreak, lost it anyway and went down in four sets. He has never taken a set off Alcaraz on a hard court, the surface both men play Tuesday.
Getting here was not clean. One dropped set per match through the first three rounds still carried him into the quarterfinal as the No. 8 seed. Shelton has said his serving, returning and baseline shot tolerance have all improved since that French Open loss 15 months ago, the kind of improvement that would need to show up immediately against a player who has beaten him each of the three times they have met.
The winner reaches the semifinals against either Frances Tiafoe or Alex Michelsen, who meet in Tuesday afternoon’s all-American quarterfinal at Arthur Ashe Stadium.
