The 2020 WGC-Mexico Championship tees off on Thursday at Club de Golf Chapultepec. Before you make any of your 2020 WGC-Mexico Championship picks, you NEED to see who Sal Johnson is backing. 

The golf media legend is coming off a strong year. He featured Tiger Woods in his best bets for the Masters and backed Brooks Koepka in his picks for the PGA Championship, and both players pulled off major victories. He completely nailed the season-ending Tour Championship. He predicted that Brooks Koepka, Rory McIlroy or Xander Schauffele could come out on top, and McIlroy won the event for the second time, with Schauffele coming in second and Koepka tied for third. Anyone who followed Johnson's advice saw HUGE returns.

He also has predicted the WGC-Mexico Championship twice since it found its home at Club de Golf Chapultepec. Before the 2018 event, he had Phil Mickelson among his best bets. "Yes this is no typo," Johnson wrote. "I really think he will contend and play well this week." He also noted Justin Thomas should be in contention, and Mickelson finished 16 under and beat Thomas in a playoff. In 2017, he pegged Dustin Johnson in his best bets, and he won the event in its first time on the high-altitude track.  

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 2020 Genesis Open. They WILL surprise you.

We can tell you Johnson wants no part of Xander Schauffele, even though the 26-year-old is 10th-ranked player in the world. Schauffele is outside the top 100 on the PGA Tour in putts per round (29.05) and is a staggering 164th in putts in the final round of tournaments at 29.80. He's a player to fade this week.

Instead, Johnson is all over a MONSTER long shot who has only gone over par once at Chapultepec! This international player is a true sleeper pick who could pull off a STUNNING PGA Tour victory. Anyone who backs this underdog could hit it BIG!
