Every golfer in the world's top 10 will be on hand this week when the 2021 WGC-Workday Championship tees off Thursday at the Concession Golf Club in Bradenton Fla.  

World No. 1 Dustin Johnson is the 13-2 favorite in the latest 2021 WGC-Workday Championship odds from William Hill Sportsbook, with Jon Rahm listed as the 10-1 second favorite. Among the other contenders in the 2021 WGC Workday Championship field are Xander Schauffele (16-1), Rory McIlroy (16-1), Justin Thomas (18-1), Patrick Cantlay (18-1) and Bryson DeChambau (20-1).

Before setting your Fantasy golf lineups or betting the 2021 WGC-Workday Championship, you HAVE 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 12 outright winners in the past year -- including 30-1 Webb Simpson at the 2020 RBC Heritage.

At last week's Genesis Invitational, half of his top 10 players finished in the top 15, including Tony Finau, who got his third straight runner-up finish worldwide. Finau missed a 6-foot birdie putt to win on 18 and Max Homa made birdie to best Finau's par on the second playoff hole. Gehman had Homa ranked 21st and noted this is "Homa season" and pointed to his T-5 finish at Riviera in 2020 as reason for optimism.      

The previous week at Pebble Beach, three of Gehman's top four picks finished in the top five, including winner Daniel Berger. And at the Farmers, the leaderboard looked like a who's who of Gehman's rankings, with five of the golf expert's top nine picks finishing tied for seventh or better.  

Gehman has been on fire all year! Two of the top four finishers at The American Express ranked in his top seven, and at the Sony, the top three in his rankings all finished in the top seven! Anyone who has followed his advice has cashed in HUGE!

Now, Gehman has ranked his top 30 players for the 2021 WGC-Workday Championship, and he is staying behind Johnson. The reigning FedEx Cup champion comes off another top-10 finish despite not being as sharp as he can be. He has three wins in his past nine worldwide starts, and he'll be near the top of the leaderboard, if not the very top, again at The Concession!     

On the other hand, Gehman is fading Thomas. The world's No. 3 player hasn't looked like himself in recent weeks, and he lost strokes in every major category at Riviera. His putter was as bad as it has been in recent memory, and it appears he might need some time to get right. The 27-year-old isn't even in Gehman's top 10! 

Instead, Gehman is looking for a lot more from a young player who comes into the event higher than 30-1! This international player opted to take last week off and should be rejuvenated. He certainly has the skill set to contend, and the unfamiliar course will level the playing field for the younger players. You ABSOLUTELY need to see who it is before betting this tournament or entering any Fantasy golf lineups.
