The first major of the year gets underway on Thursday, April 8, when the 2021 Masters tees off from Augusta National Golf Club. Defending champion Dustin Johnson (9-1) is the favorite at William Hill Sportsbook.

We simulated the Masters 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 in June. In fact, it's up nearly $10,000 on its best bets since the restart, nailing tournament after tournament. 

Last month at the AT&T Pebble Beach Pro-Am, McClure nailed Daniel Berger's win at +1400 in his best bets. McClure was also all over 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. 

After nailing Sergio Garcia (+5500) finishing on top of the leaderboard at the Sanderson Farms Championship, McClure finished up over $6,200 yet again on his best bets in that tournament. The model had him in the top five from the start and McClure's best bets included Garcia winning outright. 

The model also finished profitable at the U.S. Open, nailing two of its best bets, including a +1100 top-five bet on Matthew Wolff. Those are just some of his recent big returns. 

This same model has also nailed a whopping six majors entering the weekend, including Patrick Reed's win at Augusta in 2018! Anyone who has followed it has seen MASSIVE returns!

One major surprise the model is calling for at the 2021 Masters: Jordan Spieth, an 11-time PGA Tour winner and 2015 Masters champion, stumbles big-time and doesn't even crack the top 10!  Another surprise: Justin Thomas, whose lone major win was four years ago, makes a strong run at the title.

Also, the model is targeting FIVE golfers with odds longer than 20-1 who will make a surprising run, including an EPIC underdog getting over 30-1! Anyone who backs these long shots could hit it BIG.

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