The fourth and final golf major of the year gets underway on Thursday, July 15, when the 2021 Open Championship tees off from Royal St George's Golf Club in England. Jon Rahm, the No. 2 ranked player in the world and defending U.S. Open champion, is the 7-1 favorite in the latest 2021 Open Championship odds from William Hill Sportsbook, followed by stars like Rory McIlroy (16-1), Dustin Johnson (15-1), Brooks Koepka (16-1) and Bryson DeChambeau (14-1). 

We simulated the 2021 Open 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 Open Championship: DeChambeau, a major champion and one of the top favorites, struggles mightily doesn't even crack the top 10! Another surprise: Louis Oosthuizen, a 30-1 long shot, makes a strong run at the title. He's a target for anyone looking for a HUGE payday.

Also, the model is targeting FIVE OTHER golfers with odds of 20-1 or higher make a surprising run, including include two MASSIVE long shots higher than 35-1 that would net any bettor an EPIC payday. Anyone who backs these underdogs could hit it BIG.
