The Ocean Course at Kiawah Island will host the 2021 PGA Championship, which tees off on the South Carolina coast on Thursday. It will be the longest course ever to host a major championship. 

Two-time winner Rory McIlroy, who won his first PGA Championship on this course in 2012, is the 11-1 favorite in the latest 2021 PGA Championship odds from William Hill Sportsbook. World No. 2 Justin Thomas and third-ranked Jon Rahm are the 14-1 co-second favorites, while No. 1 Dustin Johnson is at 20-1, behind 16-1 Jordan Spieth and Bryson DeChambeau. 

Before setting your Fantasy golf lineups or betting the 2021 PGA 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 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! 

In last week's AT&T Byron Nelson, three of his top seven golfers finished in the top 10, including runner-up Sam Burns. And the previous week at Quail Hollow, four of Gehman's top 14 golfers finished in the top 10, including Rory McIlroy, who won the event to break an 18-month victory drought.

Gehman has been on fire all season! At the Zurich Classic team event in New Orleans last month, FIVE of Gehman's top eight finished T-8 or higher, including Louis Oosthuizen and Charl Schwartzel, who lost in a playoff!

At the Masters, three of Gehman's top eight picks finished in the top five! That included Jordan Spieth and Xander Schauffele, who tied for third. Three of his top seven at The Players made the top 10, and at Pebble Beach, 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 PGA Championship. We can tell you he is very high on McIlroy on this course! The Northern Irishman won his last event and seems rejuvenated now that galleries are starting to return. He was dominant before the tour's hiatus last year, and his swing work seems to be paying off. He blitzed the field on this course in 2012, winning by a tournament-record eight strokes, and he could be primed to do it again!

On the other hand, Gehman is steering clear of DeChambeau this week! The tour's biggest hitter can overpower any course, but Gehman tells SportsLine "he's just as likely to miss the cut as he is to win the PGA Championship." His massive drives are often off the mark, and that can spell big trouble at Kiawah Island. Gehman knows the U.S. Open champ can do more than just bomb it off the tee, but he doesn't even have DeChambeau in his top five this week!

Instead, the golf analyst is getting behind a HUGE long-shot who comes in at higher than 50-1 odds! This golfer has been playing better than most for the past six months, and he will be a valuable asset to your Fantasy golf lineup. You ABSOLUTELY need to see who it is, and what else Gehman is saying, before you bet the 2021 PGA Championship or enter any Fantasy golf lineups.
