Defending champion Jon Rahm and a star-studded PGA Tour field tee off Thursday at historic Muirfield Village for the 2021 Memorial Tournament as the top players prepare for the U.S. Open in two weeks. Rahm is the 10-1 favorite in the latest 2021 Memorial Tournament odds from William Hill Sportsbook. Others expected to contend for the title include Bryson DeChambeau (14-1), Rory McIlroy (14-1) and Jordan Spieth (14-1). 

Before you set any Fantasy golf lineups or bet the 2021 Memorial Tournament, you MUST see data scientist Rick Gehman's power rankings.

With his expansive database of golf statistics, course data and betting odds, Gehman creates advanced models and back-tests them constantly. These models have produced 12 outright winners in the past 18 months and three this season, including Viktor Hovland at 25-1 at the Mayakoba Golf Classic and Daniel Berger at 20-1 at Pebble Beach! 

At last week's Charles Schwab Challenge, six of Gehman's picks finished in the top 20, including Jordan Spieth, who had the 54-hole lead before finishing as the runner-up. The golf expert also ranked Charley Hoffman 12th and picked him as a long-shot winner in his best bets, and the 44-year-old shot 10 under par and tied for third. 

Gehman has been on fire all season. At the AT&T Byron Nelson, three of his top seven golfers finished in the top 10, including runner-up Sam Burns. At the Masters, three of his top eight made the top five, and at Pebble Beach earlier in the season, three of his top four had top-five finishes! Anyone who has followed his advice has cashed in HUGE!

Now, Gehman has ranked his top 30 golfers for the 2021 Memorial Tournament. We can tell you he's high on Spieth this week, calling him "the best player in 2021." On the other hand, he has Viktor Hovland listed outside the top 10 of his rankings for the Memorial. 

Instead, the golf analyst is backing a MASSIVE long-shot who comes in at triple-digit odds! This veteran has taken many trips around Muirfield and has a pretty good track record of success. You ABSOLUTELY need to see who it is, and what else Gehman is saying, before you bet the 2021 Memorial Tournament or enter any Fantasy golf lineups.
