Hideki Matsuyama has surged into the lead at the 2021 Masters at 11 under at the end of the third round. Four players sit four shots back at 7 under -- Xander Schauffele, Marc Leishman, Will Zalatoris and Justin Rose. Matsuyama is the betting favorite at William Hill Sportsbook at 5/6 (-120) heading into Sunday, followed by Schauffele at 5-1 and Rose at 9-1. 

We simulated the final round of the 2021 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: Marc Leishman, who is tied for second place heading into Sunday, finishes well outside the top five. There are far better values remaining in the field. Another surprise: Corey Conners, huge 22-1 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 THREE OTHER golfers with odds longer than 22-1 who will make a surprising run, including multiple TRIPLE-DIGIT long shots who will finish near the top of the leaderboard! Anyone who backs these long shots could hit it BIG.
