The second major of the year gets underway on Thursday, May 20, when the 2021 PGA Championship tees off from the Ocean Course at Kiawah Island Golf Resort. Rory McIlroy is the favorite at 11-1 in the latest 2021 PGA Championship odds from William Hill Sportsbook.

We simulated the 2021 PGA 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 almost $10,000 on its best bets since the restart, nailing tournament after tournament.

At the Masters in April, 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 PGA Championship: Bryson DeChambeau, the fifth-ranked player in the world and the 2020 US Open champion, stumbles big-time and barely cracks the top 10!  Another surprise: Xander Schauffele, a massive long shot at 22-1, makes a strong run at the title. He's a target for anyone looking for a huge payday.

Also, the model is targeting FOUR other golfers with odds longer than 20-1 or longer who will make surprising runs, including an EPIC underdog! Anyone who backs these long shots could hit it BIG.

So who wins the 2021 PGA Championship? And which HUGE long shots are a MUST-BACK? ... Join SportsLine right now to see who you can bank on to win the 2021 PGA Championship, 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!
