Round 4 of the PGA Championship is set for Sunday and Brooks Koepka has surged to the lead at 6-under par. Corey Conners and Viktor Hovland are one shot back at -5, while Bryson DeChambeau (-3), Justin Rose (-2), Scottie Scheffler (-2) and Rory McIlroy (-1) remain within striking distance. 

Koepka is the -105 favorite (risk $105 to win $100) to win in the latest 2023 PGA Championship odds from Caesars Sportsbook heading into Sunday. Hovland is next at 7-2, followed by Conners at 11-2 and Scheffler and DeChambeau at 9-1. 

We simulated the final round of the 2023 PGA Championship 10,000 times, and there are some MAJOR surprises. Join SportsLine now to see the shocking leaderboard.

Our proprietary model, built by DFS pro Mike McClure, has been RED-HOT since the PGA Tour resumed in June of 2020. In fact, the model is up over $8,800 on its best bets since the restart, nailing tournament after tournament.

McClure's model predicted Jon Rahm would finish on top of the leaderboard at the 2023 Sentry Tournament of Champions and The American Express. And at the 2023 Masters, the model was all over Rahm's second career major victory heading into the weekend. Rahm was two strokes off the lead heading into the third round, but the model still projected him as the winner.

In addition, the model included Nick Hardy and Davis Riley in its best bets to win the 2023 Zurich Classic. That bet hit at +4500, and for the entire tournament, McClure's best bets returned over $1,100. McClure's best bets also included Jason Day winning outright at the 2023 AT&T Byron Nelson, even though he hadn't won a PGA Tour event since 2018.

This same model has also nailed a whopping nine majors entering the weekend! Anyone who has followed it has seen MASSIVE returns! Join SportsLine here and you could win too!

One major surprise the model is calling for in the final round of the PGA Championship 2023: Conners (11-2), a two-time PGA winner who is just one shot off the lead, stumbles down the stretch and doesn't even crack the top three! 

Also, the model is targeting a trio of TRIPLE-DIGIT longshots who will be in contention late! Anyone who backs these golfers could hit it BIG. You ABSOLUTELY need to see who they are before locking in any 2023 PGA Championship picks for the final two rounds!

So who wins the PGA Championship 2023? And which HUGE longshots make a run at the title? ... Join SportsLine right now to see who you can bank on to win the 2023 PGA Championship, and see which longshots make a run at the title, all from the model that's nailed nine majors!
