Many of the world's top golfers will be back in action after a rousing U.S. Open when the 2021 Travelers Championship tees off Thursday at TPC River Highlands outside Hartford, Conn. 

William Hill Sportsbook lists Dustin Johnson and Bryson DeChambeau as the 12-1 co-favorites in its latest 2021 Travelers Championship odds, followed by Brooks Koepka at 14-1. Before you lock in any of your Fantasy golf rankings or bet the 2021 Travelers Championship, 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 13 outright winners in the past 18 months and four 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 U.S. Open, Gehman was dead-on, with 10 of his top 11 selections finishing in the top 20. That included No. 1 pick Jon Rahm, who won his first major title, and three others from those 11 picks also finished in the TOP FIVE! The only one who finished outside the top 20 was DeChambeau, who led at the turn on Sunday before a major collapse.

The golf expert knew Rahm was coming in with tremendous momentum after being forced to withdraw with a six-shot lead at the Memorial. And Gehman's observation that Rahm "has dominated Torrey Pines in his career" was made clear when the Spaniard drained long birdie putts on the final two holes to win at 6-under par. Anyone who has followed his advice has cashed in HUGE!

Now, Gehman has ranked his top 30 golfers for the 2021 Travelers Championship. We can tell you he's backing DeChambeau, who has more than enough firepower to score low at TPC River Highlands. The power hitter had a rough final round at Torrey Pines and will be eager to atone, and he has finished in the top 10 three straight years in Hartford. On the other hand, he is fading Paul Casey, who is right in the mix of favorites but barely cracks Gehman's top 10. 

Instead, the golf analyst is backing a long-shot who comes in at more than 30-1! This player appears to be on the verge of another victory, and he has played well at River Highlands before. You ABSOLUTELY need to see who it is before you bet the 2021 Travelers Championship or enter any Fantasy golf picks.
