The PGA Tour's FedEx Cup playoffs continue Thursday at Olympia Fields Country Club with the 2020 BMW Championship. New world No. 1 Dustin Johnson is the 8-1 favorite in the latest 2020 BMW Championship odds from William Hill. Before you make any 2020 BMW Championship picks of your own, you MUST check out who Sal Johnson is backing. 

A media legend and consummate golf insider, Johnson has been locked in this season, and anyone who has followed his advice has hit BIG. Last week, he pegged Johnson as one of the contenders who was coming in with momentum, and Johnson went 30 under par to win the Northern Trust by an astonishing 11 strokes!

The golf expert also knows what it takes to win in the PGA Tour playoffs, and before last year's BMW Championship at Medinah, he praised Justin Thomas in his picks. His game was "finally coming together after his wrist injury," Johnson said, and the Kentucky native went 25 under to win by three strokes!

The golf expert  was on point with his picks on the big events in 2019, featuring Tiger Woods in his best bets before he won his fifth green jacket at the Masters and promoting Brooks Koepka in his PGA Championship best bets before Koepka made a mockery of that tournament.

Johnson completely nailed the season-ending Tour Championship, predicting Koepka, Rory McIlroy or Xander Schauffele would win. Those were the top three finishers. Anyone who followed Johnson's golf picks saw HUGE returns.

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 2020 BMW Championship picks, and they WILL surprise you.

We can tell you Johnson is fading Rory McIlroy, even though he's among the favorites at 18-1 and was playing the best golf on tour before the break! But he has struggled to regain his form and could just be fine-tuning his game for the U.S. Open at Winged Foot!

Instead, Johnson is all over a MONSTER long shot who comes in at odds around 70-1! This dark horse has had a radar lock on the greens the whole season and could be primed for his first tour victory in more than three years! Anyone who backs this MASSIVE underdog could cash in BIG.
