The PGA Tour's best will be back at it this week at Bay Hill Club & Lodge near Orlando, Fla., for the 2023 Arnold Palmer Invitational. The Arnold Palmer Invitational 2023 field features 44 of the world's top 50 golfers, and they are in for a difficult test. Defending tournament champion Scottie Scheffler, Rory McIlroy and current No. 1 Jon Rahm will continue their battle for the top spot. Scheffler won last year at 5 under, beating Viktor Hovland, Tyrrell Hatton and Billy Horschel and by one stroke.    

The event tees off Thursday, and Rahm is the 7-1 favorite in the latest 2023 Arnold Palmer Invitational odds from Caesars Sportsbook. McIlroy (19-2) and Scheffler (11-1) also are top contenders in the Arnold Palmer Invitational 2023 field, followed by Max Homa (19-1), Collin Morikawa (21-1) and Justin Thomas (23-1). 

Before you lock in any 2023 Arnold Palmer Invitational picks, make sure you check out the PGA Tour predictions and best bets from golf insider Patrick McDonald.

After spending time at FanSided and NBC Sports EDGE, McDonald joined CBS Sports as a golf writer in the spring of 2022. Now covering the sport from a broader perspective, McDonald still likes to dip his toes into the betting pools on a weekly basis on the PGA Tour. 

McDonald takes a measured approach to his outright selections and is having a profitable 2022-23 season. He is up more than 20 units this season, meaning a profit of more than $2,000 for $100 bettors! 

McDonald NAILED the Farmers Insurance Open, backing Homa (25-1) as his top choice! The expert also just missed a MASSIVE 130-1 score at the Sony Open when Hayden Buckley finished as runner-up. He hit another 25-1 shot at the Houston Open, taking Tony Finau to win.

The expert finished the 2021-22 season up 42 units on his outrights, including a MONSTER 250-1 payout on Hudson Swafford at The American Express. Anyone who follows McDonald's advice has been cashing in!

Now, McDonald has sifted through the 2023 Arnold Palmer Invitational field for the best value and locked in his best bets and favorites to avoid. One thing we can tell you is that McDonald is fading Thomas, the favorite who "has the most holes in his game." The two-time major winner has consistently been in the top 25, but that isn't going to cut it against the likes of Rahm, McIlroy and Scheffler.    

Instead, McDonald is jumping on several several underdogs, including two MASSIVE longshots of well over 80-1! One of these golfers "has been experiencing a massive resurgence," the expert says, and this course is right up his alley. This player could pull off a STUNNING victory and cash in HUGE for anyone who backs him! You ABSOLUTELY need to see who it is before locking in any Arnold Palmer Invitational 2023 picks of your own!
