The first post-Masters tournament gets underway on Thursday, April 15, when the 2021 RBC Heritage tees off from Harbour Town Golf Links in South Carolina. Dustin Johnson, a native of South Carolina, is listed as the 10-1 favorite at William Hill Sportsbook.

We simulated the RBC Heritage 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 $10,100 on its best bets since the restart, nailing tournament after tournament.

Last week at the Masters, McClure nailed Jon Rahm's (+250) top-five finish, 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 few months.

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

One major surprise the model is calling for at the 2021 RBC Heritage: Abraham Ancer, who finished runner-up at this event in 2020, stumbles big-time and doesn't even crack the top 10! Another surprise: Matthew Fitzpatrick, a 30-1 long shot, makes a strong run at the title. 

Also, the model is targeting FOUR other golfers with odds of 25-1 or longer who will make a surprising run! Anyone who backs these long shots could hit it BIG.

So who wins the 2021 RBC Heritage? And which HUGE long shots are a MUST-BACK? ... Join SportsLine right now to see who you can bank on to win the 2021 RBC Heritage, and see which long shots make a run at the title, all from the model that is up over $10,000 on PGA picks since the restart!
