The 2021 3M Open features a field of 156 professional golfers vying for a $6.5 million purse, with 500 FedExCup points going to the winner. The latest 2021 3M Open odds from William Hill Sportsbook list Dustin Johnson as the 7-1 favorite, with Tony Finau and Louis Oosthuizen close behind at 14-1. Johnson, who's coming off a T-8 finish at the Open Championship, is looking for his first PGA Tour victory since the Masters in November. 

However, a loaded 3M Open 2021 field will feature fellow major champions like Sergio Garcia, Patrick Reed, Bubba Watson and Gary Woodland all vying to finish on top of the leaderboard. The 2021 3M Open tees off from TPC Twin Cities in Blaine, Minnesota on Thursday, July 22. Before locking in your 2021 3M Open picks, be sure to see the golf predictions and projected leaderboard from the proven computer model at SportsLine.

SportsLine's proprietary model, built by DFS pro Mike McClure, has been red-hot since the PGA Tour resumed last June. In fact, it's up over $10,500 on its best bets since the restart, nailing tournament after tournament.

At the 2021 Open Championship, McClure's best bets included Collin Morikawa winning outright even though he was listed as a massive 40-1 long shot. He was also all over Daniel Berger (+220) and Emiliano Grillo (+700) finishing inside the top-20. McClure's best bets netted over $2,200 at the 2021 Open Championship.

In addition, McClure's model was all over Jon Rahm's (10-1) first career major championship victory at the 2021 U.S. Open. Rahm was two strokes off the lead heading into the weekend, but the model still projected him as the winner. And at the 2021 Masters, McClure nailed Rahm's (+250) top-five finish in his best bets, as well as Corey Conners' (+550) top-10 showing.  

This same model has also nailed a whopping seven majors entering the weekend. Anyone who has followed it has seen massive returns.

Now that the 2021 3M Open field is locked, SportsLine simulated the event 10,000 times, and the results were surprising. Head to SportsLine now to see the projected 2021 3M Open leaderboard and 3M Open 2021 expert picks.

The model's top 2021 3M Open predictions 

One major surprise the model is calling for at the 2021 3M Open: Reed, a nine-time PGA Tour winner and one of the top favorites, struggles and barely cracks the top five. Reed remains one of the best putters on tour, ranking inside the top-10 in strokes gained: putting (.674), overall putting average (1.554), total putting (84.8) and one-putt percentage (44.28). 

However, the former Masters champion is hitting fewer than 63 percent of greens in regulation this season, which ranks 169th on tour. His inability to find the green in regulation has resulted in Reed finishing T-25 or worse in each of his last three starts. He's also missed the cut in three of his last nine events. He's not a strong pick to win it all and there are far better values in the 3M Open 2021 field.

Another surprise: Cameron Tringale, a massive 28-1 long shot, makes a deep run at the title. Tringale enters the 2021 3M Open as one of the best putters on tour. In fact, Tringale ranks inside the top-15 in total putting (107.7), putting average (1.729) and 3-putt avoidance (1.81). 

Tringale also ranks 16th in scoring average (69.992) and 23rd in birdie average (4.11). The 33-year-old American has recorded four top-10 finishes this season, and he had tremendous success at this event last year, securing a T-3 finish at the 3M Open in 2020. Those impressive stats, plus his long odds, make Tringale a strong play for your 2021 3M Open bets. 

How to make 2021 3M Open picks

The model is targeting five other golfers with 2021 3M Open odds of 28-1 or higher to make a strong run at the title. Anyone who backs these underdogs could hit it big. You can only see them here.
