The 2021 PGA Championship begins Thursday on the Ocean Course at Kiawah Island Golf Resort. After adding 200 yards since the PGA Championship was last played on the world-class course, it will be the longest layout in major championship history. With unpredictable winds blowing off the Atlantic Ocean, players have been advised to practice from multiple tees since 14 holes could play from any tee box based on wind. With the PGA Championship 2021 players heading to the tees starting at 7 a.m. ET, who can you trust with your golf picks?

Rory McIlroy has never had any trouble with distance and navigated the wind brilliantly in 2012 to win the PGA Championship by eight strokes at this same venue. Accordingly, he's the 11-1 favorite in the 2021 PGA Championship odds from William Hill Sportsbook coming off a win two weeks ago. Jordan Spieth is fresh off his seventh top-10 in his last nine starts and is listed at 16-1. Before locking in your 2021 PGA Championship picks or entering any PGA DFS tournaments on sites like DraftKings and FanDuel, be sure to see the 2021 PGA Championship predictions and projected leaderboard from the proven computer model at SportsLine.

The 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. In fact, 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 its golf picks has seen massive returns.

Now that the 2021 PGA Championship field is taking shape, SportsLine simulated the event 10,000 times, and the results were surprising. Head to SportsLine now to see the projected leaderboard.

One huge shocker the model is calling for at the PGA Championship 2021: Bryson DeChambeau, the fifth-ranked player in the world and the 2020 US Open champion, stumbles big-time and barely cracks the top 10. The 2020 US Open champion is the fifth-ranked player in the world and leads the tour in driving distance.

Excelling at the Ocean Course relies more on accuracy than distance, and that's where DeChambeau falls short. He ranks 172nd in driving accuracy percentage and is also outside the top 50 in greens in regulation percentage. With much of the course bordering the Atlantic Ocean, fierce winds can affect ball flight, so precision is mandatory to performing well.

DeChambeau also won't enter the PGA Championship 2021 with momentum since he's struggled in recent tournaments. He's coming off a 55th-place finish at last week's AT&T Byron Nelson and has finished outside the top 40 in three of his last four tournaments. DeChambeau is always impressive off the tee, but that alone won't carry him at Kiawah Island, so your 2021 PGA Championship bets may be better served elsewhere.

Another surprise: Xander Schauffele, a 22-1 long shot in the latest PGA Championship 2021 odds, makes a strong run at the title. Schauffele has a much better chance to win than his PGA odds imply, so he's a target for anyone looking for a huge payday. The 27-year-old is a four-time PGA Tour winner and becoming a fixture near the top of major championship leaderboards in four years as a pro.

Schauffele has eight top-10 finishes in just 15 career starts in majors, including runner-up finishes at the 2018 Open Championship and 2019 Masters as well as third-place finishes at the 2019 U.S. Open and 2021 Masters. Schauffele currently ranks second on the PGA Tour in total strokes gained per round (1.890) and is fourth in the Official World Golf Ranking thanks to top-20 finishes in 12 of his last 14 starts.

The model is also targeting four golfers with odds longer than 20-1 to make a strong run at the title, including an epic underdog. Anyone who backs these underdogs could hit it big. You can only see them here.
