There are 70 players in the field at this week's 2020 BMW Championship vying for just 30 spots in the season-ending Tour Championship. That means the quality of golf will be higher than it has been all season in the second event of the 2020 FedEx Cup Playoffs. The lure of the $15 million prize for the FedEx Cup champion makes every shot critical at Olympia Fields Country Club. The first 2020 BMW Championship tee times are on Thursday at 12:30 p.m. ET from Chicago's south suburbs.

Bryson DeChambeau, who won the Rocket Mortgage Classic and has five top-10 finishes since the PGA Tour's restart, is 12-1 this week in the latest 2020 BMW Championship odds from William Hill. New world No. 1 Dustin Johnson is at 8-1 and on top of the PGA odds board, while former top-ranked players Jon Rahm and Justin Thomas are not far behind at 10-1 and 12-1, respectively. Before locking in your 2020 BMW Championship picks or entering any PGA DFS tournaments on sites like DraftKings and FanDuel, be sure to see the latest golf 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 almost $9,300 on its best bets since the restart, nailing tournament after tournament. 

McClure finished profitable yet again last week at the Northern Trust, nailing three of his best bets, including a 7-1 top-five bet on Daniel Berger. After hitting a top-five bet (12-1) on Doc Redman at the Wyndham Championship, McClure finished up over $700 in that event. The model was all over Justin Thomas winning the WGC-FedEx St. Jude Invitational at 12-1. At the 3M Open, McClure's best bets returned a whopping $1,100 as he nailed a top-five pick on Max Homa (12-1) and a top-20 pick on Talor Gooch (4-1). 

At the Memorial Tournament, McClure used the model to identify winner Jon Rahm (22-1) as one of his best bets from the start. It also had him as the projected winner heading into the weekend. The model was all over long shot winner Collin Morikawa at the Workday Charity Open. It identified him as a top contender from the start despite his long odds and McClure recommended an outright bet on him to win at 33-1. The model also called Bryson DeChambeau taking the Rocket Mortgage Classic.

McClure returned a whopping +788 during the 2020 Charles Schwab Challenge, including nailing top-five bets on Xander Schauffele at 13-2 and Collin Morikawa at 9-1. The model was also extremely high on 30-1 long shot winner Webb Simpson at the RBC Heritage. The model had him in the top five from the start and McClure's best bets included Simpson winning outright. 

In all, the advanced computer model has nailed a whopping six majors entering the weekend, including two of the last four. Anyone who has followed its golf picks has seen massive returns returns. 

Now that the 2020 BMW Championship field is locked, 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 2020 BWM Championship predictions 

One huge shocker the model is calling for at the BMW Championship 2020: Dustin Johnson, the top favorite at 8-1, stumbles and doesn't even crack the top three. Johnson is perhaps the hottest golfer on tour after finishing second at the PGA Championship and running away with the Northern Trust. He also won the BMW Championship in 2016 and 2010.

However, he hasn't had much success at this event the past few years. He hasn't cracked the top 20 at the BMW Championship since his 2016 win and settled for a disappointing 57th last year. He's also missed two cuts since the restart this year, so consistency has been an issue. With extremely short golf odds this week and a loaded field looking to catch him in the standings, the model has identified Johnson as one of the 2020 BMW Championship favorites to fade. 

Another surprise: Xander Schauffele, a 20-1 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 10th-ranked player in the world, Schauffele enters this week at No. 11 on the FedEx Cup standings, a virtual lock to make the Tour Championship's 30-player field. 

Schauffele has done everything but win so far in the 2019-20 PGA Tour season, finishing second at the WGC-HSBC Champions and Sentry Tournament of Champions. He was also third at the Charles Schwab Challenge as part of a stellar campaign that has earned him over $3.7 million. Schauffele has made every cut since the reboot, including a sixth at the WGC-FedEx St. Jude Invitational and a 10th at the PGA Championship. Schauffele is fifth on tour in strokes gained: tee to green, and sixth in greens in regulation (71.77 percent), which is why SportsLine's model is riding him for its 2020 BMW Championship bets.

Also, the model is targeting four other golfers with odds of 20-1 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.
