Bettors at one Las Vegas casino clearly have a favorable opinion of Auburn quarterback Jarrett Stidham.

As of Monday, the Westgate casino sportsbook lists Stidham with 20-to-1 odds to win the Heisman Trophy. He is the only one of 42 players listed to see his odds improve since April 9, the day after Stidham was Auburn's Offensive MVP on A-Day, when he was listed at 50-to-1.

Stidham is tied with seven other players, including Alabama's Jalen Hurts and Bo Scarbrough and LSU's Derrius Guice, for the eighth-best odds.

The seven players with the best odds are all quarterbacks.

Southern Cal's Sam Darnold, who attended last month's QB Summit with Stidham and others, is the favorite at 5-to-1. Oklahoma's Baker Mayfield (8-to-1), Louisville's Lamar Jackson (8-to-1), Ohio State's J.T. Barrett (10-to-1), Washington's Jake Browning (12-to-1), Florida State's Deondre Francois (12-to-1) and Oklahoma State's Mason Rudolph (15-to-1) are second through seventh, respectively.

There was no change in the odds for Auburn running back Kamryn Pettway, who remains listed at 30-to-1.

The Bovada online sportsbook does not list Stidham, but has Pettway at 33-to-1.
