The 2021 Travelers Championship tees off Thursday, June 24, from TPC River Highlands. Dustin Johnson and Bryson DeChambeau are the 12-1 co-favorites in the latest 2021 Travelers Championship odds from William Hill Sportsbook, followed by Brooks Koepka (14-1).

We simulated the 2021 Travelers Championship 10,000 times, and there are some MAJOR surprises.

Our proprietary model, built by DFS pro Mike McClure, has been RED-HOT since the PGA Tour resumed last June. In fact, it's up over $9,000 on its best bets since the restart, nailing tournament after tournament.

At the 2021 U.S. Open, McClure's model was all over Jon Rahm's first career major championship victory at 10-1 from the start. Rahm was two strokes off the lead heading into the weekend, but the model still projected him as the winner. And at the 2021 Masters, McClure nailed Rahm's (+250) top-five finish in his best bets, as well as Corey Conners' (+550) top-10 showing. McClure's best bets netted over $450 at the Masters.

In addition, McClure was all over Daniel Berger's win at +1400 in his best bets at the AT&T Pebble Beach Pro-Am in February. McClure also nailed Viktor Hovland's (+2500) victory in the Mayakoba Golf Classic in December. That was one of many huge calls he's made in the past several months.

This same model has also nailed a whopping seven majors entering the weekend! Anyone who has followed it has seen MASSIVE returns!

One major surprise the model is calling for at the 2021 Travelers Championship: Koepka, who is coming off a fourth-place finish at the U.S. Open and is one of the top favorites, struggles mightily and doesn't even crack the top five! Another surprise: Abraham Ancer, a big 33-1 long shot, makes a strong run at the title. He's a target for anyone looking for a HUGE payday.

Among the options the model is touting is a long shot who comes in at well over 40-1 in the Travelers Championship odds 2021. Pure ball-strikers who can putt well excel at TPC River Highlands, and this sleeper fits the bill perfectly! Anyone who backs this underdog could cash in HUGE.
