The PGA Championship used to have the moniker "Glory's Last Shot" due to its final spot in the four-tournament grand slam of golf. However, a move to May has made events like the 2021 PGA Championship the second of the four majors in the grand slam rotation. The Ocean Course at Kiawah Island in South Carolina will host the PGA Championship 2021 beginning on Thursday, May 20, with 156 of the world's best looking to take their shot at the Wanamaker Trophy.

World No. 1 Collin Morikawa is 11-1 atop the latest 2021 PGA Championship odds from William Hill Sportsbook. Former No. 1 players Jon Rahm and Justin Thomas are right behind at 12-1, while defending U.S. Open champ Bryson DeChambeau is 14-1 on the PGA odds board. Before locking in your 2021 PGA Championship picks, be sure to see the 2021 PGA Championship predictions and projected leaderboard from the proven computer model at SportsLine.

SportsLine's prediction model, built by DFS pro Mike McClure, has been on fire since the return of the PGA Tour in June. In fact, it's up over $10,000 on its best bets since the restart, nailing tournament after tournament.

At the 2021 Masters, McClure nailed Jon Rahm's (+250) top-five finish, as well as Corey Conners' (+550) top-10 showing. All told, 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.

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. He also finished profitable at the U.S. Open, nailing two of his best bets, including a +1100 top-five bet on Matthew Wolff.

This same model has also 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 2021 PGA Championship leaderboard.

The model's top 2021 PGA Championship predictions 

One major surprise the model is calling for at the PGA Championship 2021: Bryson DeChambeau, the defending U.S. Open champion and one of the top favorites, struggles and barely cracks the top 10. DeChambeau has been one of the hottest players on tour this season, finishing on top of the leaderboard at the U.S. Open and Arnold Palmer Invitational.

The eight-time PGA Tour champion has been sensational off the tee this season, ranking first in driving distance, strokes gained tee to green and strokes gained off the tee. DeChambeau's length off the tee also has him ranked inside the top 12 in both scoring average and birdie average.

However, DeChambeau is hitting fewer than 60 percent of fairways off the tee, which can cause plenty of trouble at Kiawah Island. His inability to find the fairway off the tee has resulted in DeChambeau finishing outside the top 40 in his last two starts on the PGA Tour, which includes a 46th finish at the Masters. He's not a strong pick to win it all and there are far better values in the PGA Championship 2021 field.

Another surprise: Patrick Cantlay, a 25-1 long shot, makes a strong run at the title. He has a much better chance to win it all than his odds imply, so he's a target for anyone looking for a huge payday. The former top-ranked amateur golfer in the world has enjoyed two top-10s in his major championship history and is now eying a Wanamaker Trophy for his mantle.

Cantlay is currently seventh in the FedEx Cup standings and has won over $3.5 million already this season. A chunk of that came via the winner's share of the Zozo Championship at Sherwood, along with a runner-up showing at the American Express and a third at the AT&T Pebble Beach Pro-Am. Cantlay has one of the world's top short games, as he is sixth on the PGA Tour in strokes gained around the green and second in scrambling. Those assets will serve him well around Kiawah Island's tricky greens and are a reason why Cantlay should be considered in your 2021 PGA Championship bets, according to the model.

How to make 2021 PGA Championship picks

The model is targeting four other golfers with PGA Championship odds 2021 higher than 20-1 to make a strong run at the Wanamaker Trophy. Anyone who backs these underdogs could hit it big. You can only see them here.
