Ben Shelton knocked out the defending champion at 3:33 in the morning, beat Frances Tiafoe on Friday night, and reached his first Grand Slam final. He walks onto Arthur Ashe on Sunday getting plus money. The US Open final odds have Alexander Zverev at -132 and Shelton at +109 at DraftKings, with Kalshi trading the German at 58 cents against Shelton’s 43.
Both numbers are defensible. The interesting part is how each man arrived at his, because one of them got most of the way there without playing.
Where Zverev’s Price Came From
Zverev started the fortnight around +300, second choice behind Carlos Alcaraz, who sat somewhere between +195 and +250 depending on the book. Shelton opened at +1000. Alcaraz shortened as he advanced and ESPN had him as short as -165, which works out to a shade over 62 percent.
Then Shelton beat him in five sets, in a quarterfinal that finished later than any match in the tournament’s history. ESPN reported the board immediately afterward: Zverev to -110, Shelton from +850 to +150, Tiafoe from 22-1 to +700.
Convert those and the shape shows up. Zverev went from roughly 25 percent to 52, a gain of about 27 points of implied probability, earned on an afternoon when he was not on court. Beating Khachanov in his own semifinal on Friday moved him another four and a half, from -110 to -132. The match he didn’t play was worth six times the match he did.
US Open Final Odds and a Soft Draw
Look at who Zverev has actually beaten here. Lorenzo Sonego and Quentin Halys took him to five sets in the first two rounds, which made him the first top seed to open a major that way. After that came Alejandro Tabilo, the 25 seed, then Luciano Darderi at 21, then an unseeded Botic van de Zandschulp, then an unseeded Khachanov.
Six matches, and the highest-ranked opponent was seeded 21st. Shelton will be the first top-20 player Zverev has faced all fortnight, and he’ll be facing him in the final.
Shelton’s route looks different. He beat the tournament favorite, then the 11th seed, and his reward for both is a price that’s still got a plus sign in front of it.
The Case for the Favorite
Here’s where my own argument stops being comfortable. Zverev is 5-0 lifetime against Shelton and has won the last ten sets they’ve played. Six years of results in one specific matchup is the most direct information anyone has about Sunday, and no draw produced it.
The rest of his season holds up too. Zverev is 24-2 in Grand Slam matches this year, having lost only to Alcaraz in the Australian Open semifinals and to Jannik Sinner in the Wimbledon final. He won Roland Garros in June for the first major title of his career. Sunday is his third consecutive major final and the sixth of his career.
A soft draw describes the bracket. Zverev didn’t choose his opponents, and beating the people in front of you is the entire job. Anyone treating the draw as evidence of weakness is doing the same thing as anyone treating Shelton’s Alcaraz win as proof he’s arrived. Both read a small sample and call it a pattern.
Worth adding that Zverev is the top seed here partly by default. He’s ranked second in the world, and we wrote about the withdrawal that moved him up when Sinner pulled out injured in August.
What Nobody Knows Before Sunday
Zverev has been the favorite in a US Open final before. In 2020 he won the first two sets against Dominic Thiem and lost in a fifth-set tiebreak, and Thiem became the first man since 1949 to take the title after dropping the opening two. Zverev is 1-4 in major finals going into this one. Whether that’s a pattern or five separate afternoons is exactly the sort of question nobody can answer in advance, which is why our page on underdog betting philosophy keeps circling back to sample size.
The American side of it carries its own weight. No American man has won a major since Andy Roddick took this title in 2003, a drought of 23 years, and a Shelton win would also make him the first Black men’s champion here since Arthur Ashe in 1968. None of that prices a tennis match, though it does explain what Arthur Ashe will sound like on Sunday.
Strip the noise out and the number is close. Zverev at -132 implies about 57 percent, Shelton at +109 about 48, and the two add to roughly 105 with the vig included. Take the vig out and it lands nearer 54-46, a market leaning one way while calling the match close. That’s a long way from the certainty you’ll hear in either direction this weekend. The long-run underdog rates on our data pages are the only honest frame for a single match, and where a price moved from matters less than where it sits. ESPN has the full board for both finals.
Zverev has lost two matches at majors all year, to Alcaraz and to Sinner. Neither of them is in this final. Sunday is the sixth time he’s played Ben Shelton, and he’s won the other five.
