The year's first major, the PGA Championship, gets underway Thursday at TPC Harding Park in San Francisco. Before setting your Fantasy golf lineups or betting this tournament, you NEED to 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 11 outright winners in the past year -- including 30-1 Webb Simpson at the 2020 RBC Heritage, 50-1 Chez Reavie at last year's Travelers and 40-1 Patrick Reed at the Northern Trust among nine PGA Tour winners -- plus a $10,000 DraftKings win at The Masters.

At the Rocket Mortgage Classic last month, Gehman put Bryson DeChambeau atop his Fantasy rankings. The result? DeChambeau fired a 23-under, winning by three strokes. Then at the Workday Charity Open, Gehman was higher than most on Collin Morikawa, and he won in a dramatic playoff over Justin Thomas. Gehman had pegged Thomas at No. 2. Before the Memorial Tournament, Gehman told SportsLine readers that Jon Rahm "could be on the brink of breaking out." Rahm cruised to a three-shot win. 

Moreover, at this year's WGC-Mexico Championship, four of Gehman's top six golfers finished tied for sixth or better! 

Now, Gehman has revealed his top 30 players for the PGA Championship. We can tell you he's very high on Bryson DeChambeau, saying "he has the skill-set that will be so valuable at TPC Harding Park." He's also fading Jordan Spieth, noting, "The big concern is whether he can hit enough fairways to stay competitive at TPC Harding Park."

Strikingly, Gehman loves a long shot higher than 65-1 who thrives on the Tour's most difficult courses. This international player's recent play has Gehman predicting he shows "elite form" this week. You ABSOLUTELY need to see who it is before betting this tournament or entering any Fantasy golf lineups.
