Augusta National Golf Club annually calls out to the world with azaleas and dogwoods that signal the true beginning of golf season. That wasn't the case in 2020, as COVID-19 pushed the Masters back to November. However, Thursday, April 8 will signal a return to normalcy, when the 2021 Masters tees off with Dustin Johnson as its defending champion. Johnson, the current world No. 1, is the 6-1 favorite in the latest 2021 Masters odds from William Hill Sportsbook.

Former world No. 1 Jon Rahm and Rory McIlroy, who only needs the Masters to complete the career Grand Slam, are both 10-1. Two-time U.S. Open champion Brooks Koepka is 11-1, while Justin Thomas and Bryson DeChambeau are 12-1 among the top 2021 Masters favorites, according to oddsmakers. Before locking in any 2021 Masters picks, be sure to see the 2021 Masters 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 $10,700 on its best bets since the restart, nailing tournament after tournament.

In the final standard PGA event of 2020, McClure nailed Viktor Hovland's win at +2500 in his best bets. That was one of many huge calls he made last year. 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. The model had him in the top-five from the start and McClure's best bets included Garcia winning outright. Those who followed that advice saw a massive +5500 return. 

He also finished profitable at the U.S. Open, nailing two of his best bets, including a +1100 top-five bet on Matthew Wolff. McClure hit a top-five bet (+1200) on Doc Redman at the Wyndham Championship, finishing up over $700 on his best bets. Those are just some of his recent big returns. 

In all, the advanced computer model has also nailed a whopping six majors entering the weekend, including Patrick Reed's Masters win in 2018. Anyone who has followed its golf picks has seen massive returns. 

Now that the 2021 Masters 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.

The model's top 2021 Masters predictions 

One huge shocker the model is calling for at the Masters 2021: Brooks Koepka, a four-time major champion and one of the top favorites, fails to crack the top 10. Koepka had a strong showing at the Masters last November, earning a seventh place finish at Augusta National. The 30-year-old also recorded his eighth career PGA Tour victory earlier this month at the Phoenix Open. However, Koepka missed the cut in three consecutive events before breaking through at TPC Scottsdale. 

Koepka's inconsistent performances can be directly attributed to his inability to find the fairway off the tee. He currently ranks 184th in driving accuracy percentage (54.61), which doesn't bode well for his chances to finish on top of the 2021 Masters leaderboard at Augusta National. He's not a strong pick to win it all and there are far better values in the 2021 Masters field.

Another surprise: Daniel Berger, a 40-1 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 15th-ranked player in the world, Berger has four victories on the PGA Tour, but is still looking for his major championship moment. Berger got back in the winner's circle for the second time in less than a year in February, firing a final-round 65 to secure the AT&T Pebble Beach Pro-Am. That victory came after placing 10th at the Sentry Tournament of Champions and seventh at the Sony Open in Hawaii.

Berger has made the cut in all three of his previous Masters appearances, including a 10th in his maiden attempt in 2016. He's 15th on the PGA Tour in strokes gained putting, will be advantageous on Augusta National's pristine surfaces. That ability and his nearly year-long run of strong play make Berger one of the desirable players for your 2021 Masters bets, according to the model.

How to make 2021 Masters picks

The model is targeting three other golfers with odds of 25-1 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.
