Before you pick this week's BMW Championship, you'll want to see who Sal Johnson is backing. The golf media legend is hot this year. For the Masters, Johnson featured Tiger Woods in his best bets. For the PGA Championship, Johnson was all over Brooks Koepka. The result: both won in historic fashion, and anyone who followed Johnson's lead hit it BIG.

At the Travelers Championship in June, Johnson promoted 50-1 long shot Chez Reavie as a possible winner, noting his game suited TPC River Highlands to a tee. The result: Reavie cruised to a four-stroke victory, finishing 17-under for his first PGA title in 11 years! Last month at TPC Southwind, Johnson again promoted Koepka as one of his best bets. The result: Koepka went 16-under to win the WGC-FedEx Invitational.

Now, Johnson -- the first producer of "Inside the PGA Tour," a longtime ABC Sports golf producer and the founder of the world's biggest golf stats database -- has issued his highly confident picks for the 2019 BMW Championship at Medinah Country Club.

We can tell you Johnson wants no part of Dustin Johnson, one of the top Vegas favorites at 14-1. In fact, he says Johnson doesn't even crack the top 10. "As we have said all summer, his biggest problem is putting," Sal Johnson told SportsLine. "He's 186th in putting inside 10 feet, and he's also lackluster at scrambling, ranking tied for 107th. Since his runner-up finish at the PGA Championship, he hasn't been better than 20th in his last six starts. His game seems lost right now."

Instead, Johnson is high on a COLOSSAL long shot who's getting no respect despite rising rocketing up the FedEx Cup standings in recent weeks. This overlooked player ranks near the top in strokes gained off the tee, the key metric for success at Medinah Country Club. Anyone who backs this underdog could hit it BIG.
