Phil Mickelson's storybook PGA Championship win is in the history book, and now he will try to win his third tournament title at the 2021 Charles Schwab Challenge, which tees off Thursday at Colonial Country Club in Fort Worth, Texas. 

Dallas native and previous champion Jordan Spieth is the 10-1 favorite in the latest 2021 Charles Schwab Challenge odds from William Hill Sportsbook. World No. 2 Justin Thomas (12-1) is the second favorite from the the 2021 Charles Schwab Challenge field, followed by Collin Morikawa (14-1) and defending champion Daniel Berger (20-1), who beat Morikawa in a playoff last year. 

Before setting your Fantasy golf lineups or betting the 2021 Charles Schwab Challenge, 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! 

Last week before the PGA Championship, Gehman had five players in his top 10 who finished 30th or better. He also noted Mickelson's strong play heading into the tournament and indicated the veteran lefty could shake things up.

"We've seen flashes of brilliance from Mickelson, and the metrics are trending in the right direction," Gehman told SportsLine before the event. "If he can hold it together for four rounds, he can certainly make some noise."

Did he ever. The 50-year-old went 6 under par to win by two strokes. In winning the sixth major championship of his career, he became the oldest player to win a major title.

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 Charles Schwab Challenge. We can tell you he is looking for a big rebound from Thomas this week! The 28-year-old missed the cut at the PGA, but he came up just inches short on a birdie putt on 18 that likely would have gotten him to the weekend. He didn't play that poorly, and he did win the Players earlier this year and remains one of the best ball-strikers on tour. Gehman isn't shying away from him at Colonial!

On the other hand, Gehman is steering clear of Scottie Scheffler, even though he is listed in a group of contenders at 25-1 and played better than most at Kiawah Island. The 24-year-old was one of the few golfers to go under par in both weekend rounds last week, but this will be only his second time at Colonial. Last week was his first top-10 finish in a full-field event since the end of February, so Gehman advises you to go in another direction and barely ranks Scheffler in his top 15.

Instead, the golf analyst is getting behind a long-shot who comes in at higher than 40-1 odds! This veteran knows his way around Colonial as well as anyone, and his stats right now measure up with many much more notable names. He comes off a solid finish at the PGA, and this is the time to grab him for your Fantasy golf lineup. You ABSOLUTELY need to see who it is, and what else Gehman is saying, before you bet the 2021 Charles Schwab Challenge or enter any Fantasy golf lineups..
