The PGA Tour visits the Motor City this week, and Bryson DeChambeau is preparing to defend his title at the 2021 Rocket Mortgage Classic, which tees off Thursday. DeChambeau dominated at Detroit Golf Club last year, going 23-under par to beat Matthew Wolff by three strokes. Officials have tried to make the course more difficult by letting the rough grow out this year, but the fairways are straight and the hazards are limited, so the players will bomb away and scores are expected to go low. Nate Lashley won the inaugural event in 2019 at 25-under par.  

William Hill Sportsbook is looking for DeChambeau to dominate again, listing him as the 15-2 favorite in its latest 2021 Rocket Mortgage Classic odds. The 2020 U.S. Open champion is followed by three other major winners, with 2018 Masters champ Patrick Reed (14-1), reigning Augusta champ Hideki Matsuyama (14-1) and 2012 U.S. Open winner Webb Simpson (18-1) also expected to contend. Before you lock in your 2021 Rocket Mortgage Classic picks, you really need to see who esteemed golf insider Sal Johnson is backing.

A media legend and consummate golf insider, Johnson has a tremendous feel for how the players and courses fit together. Before last year's Rocket Mortgage Classic, he was locked in on DeChambeau before the bomber's debut in Detroit. 

"This is a course he should eat up and play great on," Johnson said before the event. "Look for him to break out with a possible win."

The result? DeChambeau crushed it all week and didn't shoot higher than 67 on his way to a 23-under finish. He fired a 7-under 65 on the final day to beat Matthew Wolff by three strokes. 

Now Johnson, the first producer of "Inside the PGA Tour," a longtime ABC Sports golf producer who worked with Jack Nicklaus, Arnold Palmer and Greg Norman, and the founder of the world's top golf stats database, has released his highly confident 2021 Rocket Mortgage Classic picks, and they will surprise you. You can only get those picks and Johnson's expert PGA predictions and analysis on SportsLine.

Top 2021 Rocket Mortgage Classic expert picks

Shockingly, the golf expert is fading Will Zalatoris, who is among the top-five favorites at William Hill at 25-1. The 24-year-old stormed onto the scene with top-eight finishes in three of the first four events to start the season. Then he was the runner-up at the Masters in April and tied for eighth at the PGA Championship. But he has a T-59 and two missed cuts in his last five events, and he is making his Rocket Mortgage debut. 

On the other hand, Johnson has been obsessed with figuring out DeChambeau's game. Obviously, it's a power game, as he leads the tour in driving distance (322.4) and strokes gained: off-the-tee. Consistency has been lacking, but he ranks sixth in the world and has eight tour wins. That includes the Arnold Palmer in March, but he has been up and down since finishing T-3 at the Players Championship the following week. He tied for 19th last week and has shot 70 or better in six of his last seven rounds, the only exception being his final-round 77 at the U.S. Open.      

Johnson knows that Reed's game has been consistent this season and isn't surprised he is among the favorites. He has been in the top 25 in 13 of 18 events, with six of those in the top 10. His win at the Farmers Insurance Open at the end of January was his ninth tour victory, and he is ninth in the Official World Golf Ranking. His statistics stack up well for Detroit Golf Club, as he ranks first in one-putt percentage (44.91) and eighth in strokes gained: putting, which will help on the tiered greens. He also has shot 70 or better in five straight rounds. 

How to make 2021 Rocket Mortgage Classic predictions

Johnson is touting a major long shot this week who comes in at well over 40-1. This player has taken a strong liking to the Detroit Golf Club, and his game appears to be coming around quickly. He could pull off a massive victory this week, and you'll want to profit from it, too. Anyone who backs this underdog could cash in huge. You can only get this pick on SportsLine
