Jon Rahm, the No. 2 ranked player in the world, has surged to a four-shot lead (-12) in the 2020 Memorial Tournament heading into the final round on Sunday. He's the heavy favorite, according to William Hill at 2-9, but Tony Finau and Ryan Palmer are lurking four shots behind at 8-under par. We simulated the final round of the 2020 Memorial Tournament 10,000 times, and there are some MAJOR surprises.

Our proprietary model, built by DFS pro Mike McClure, was all over long shot winner Collin Morikawa last week 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. Additionally, it has nailed two of the last three majors entering the weekend.

The model predicted Gary Woodland's first career major championship at the U.S. Open even though he wasn't the favorite entering the weekend. The result: Woodland held off a late charge from Brooks Koepka and won by three strokes. The model also called Koepka's historic victory at the 2019 PGA Championship, predicting he'd hold his lead in the home stretch. In all, the advanced computer model has nailed a whopping six majors entering the weekend.

And already this season, the model called Justin Thomas (15-2) winning the CJ Cup, Rory McIlroy (11-2) taking down the WGC-HSBC Champions and Viktor Hovland (11-1) earning his first career PGA Tour victory at the Puerto Rico Open. Using the model for his best bets, 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. Those who followed that advice saw a whopping +3000 return! Anyone who has followed it has seen MASSIVE returns. 

One major surprise the model is calling for Sunday: Danny Willett, who shot a 66 in Round 2 and enters Sunday within six shots of the lead, stumbles and barely cracks the top five! Another surprise: Jason Day, a 40-1 long shot, makes a strong run at the title. He's a target for anyone looking for a HUGE payday. 

Also, the model says several triple-digit long shots will make a strong run on Sunday. Anyone who backs these underdogs could hit it BIG.
