The PGA Tour's Florida swing always draws talented fields, and among the best have assembled outside Orlando beginning on Thursday for the 2021 Arnold Palmer Invitational. Played at the 7,454-yard, par-72 Bay Hill Golf Course, the 2021 Arnold Palmer Invitational delivers a three-year exemption and 550 FedEx Cup points to the winner. Defending champion Tyrrell Hatton will try to win his second straight red cardigan at Bay Hill, but standing in his way is a world-class field that includes 2018 champ Rory McIlroy, Justin Rose, Rickie Fowler, Bryson DeChambeau and Patrick Reed.

A four-time major winner and former world No. 1, McIlroy is the 9-1 favorite in the 2021 Arnold Palmer Invitational odds at William Hill Sportsbook. Viktor Hovland and DeChambeau are both at 12-1, while Hatton is being listed at 16-1 on the PGA odds board. Before locking in your 2021 Arnold Palmer Invitational picks or entering any PGA DFS tournaments on sites like DraftKings and FanDuel, be sure to see the latest golf predictions and projected leaderboard from the advanced computer model at SportsLine.

SportsLine's prediction model, built by DFS pro Mike McClure, has been on fire since the return of the PGA Tour last June. In fact, it's up almost $11,000 on its best bets since the restart, nailing tournament after tournament.

Last month at the AT&T Pebble Beach Pro-Am, McClure nailed Daniel Berger's win at +1400 in his best bets. McClure was also all over Viktor Hovland's (+2500) victory in his best bets at the Mayakoba Golf Classic in December. That was one of many huge calls he's made in the past few months. 

After nailing Sergio Garcia (+5500) finishing on top of the leaderboard at the Sanderson Farms Championship, McClure finished up over $6,200 yet again on his best bets in that tournament. The model had him in the top five from the start and McClure's best bets included Garcia winning outright. 

He also finished profitable at the U.S. Open, nailing two of his best bets, including a +1100 top-five bet on Matthew Wolff. In all, the advanced computer model has also nailed a whopping six majors entering the weekend. Anyone who has followed its golf picks has seen massive returns. 

Now that the 2021 Arnold Palmer Invitational field is locked, SportsLine simulated the event 10,000 times, and the results were surprising. Head to SportsLine now to see the projected leaderboard.

The model's top 2021 Arnold Palmer Invitational predictions 

One huge shocker the model is calling for at the Arnold Palmer Invitational 2021: Jordan Spieth, who has won 11 times on the PGA Tour and is one of the top Vegas favorites, stumbles and doesn't even crack the top 10. Spieth is making his Bay Hill debut, and is coming off a torrid stretch of golf that saw him contend on Sunday in three straight events.

Spieth led the Waste Management Phoenix Open late, until a Sunday 72 saw him finish fourth at TPC Scottsdale. The next week on the Monterey Peninsula, Spieth again was around the lead before finishing third at the AT&T Pebble Beach Pro-Am. And two straight 68s to open the Genesis Invitational had Spieth in contention for a third straight week before finishing 15th at Riviera. But Spieth's unfamiliarity at Bay Hill might prove costly, and there are far better values in the Arnold Palmer Invitational 2021 field.

Another surprise: Hideki Matsuyama, a 28-1 long shot, makes a strong run at the 2021 Arnold Palmer Invitational title. Matsuyama has a much better chance to win it all than his odds imply, so he's a target for anyone looking for a huge payday. 

A five-time winner on the PGA Tour, Matsuyama is coming off a strong week – finishing 15th at the WGC-Workday Championship at The Concession. Matsuyama also has a second-place finish at the Houston Open, a 13th-place showing at the Masters and a 17th-place finish at the U.S. Open on his resume this season. 

Matsuyama has made the cut in all six previous Arnold Palmer Invitationals he has appeared in, including a sixth-place finish at the 2016 tournament won by Jason Day. Matsuyama is 20th on tour this season in total birdies, which is a strong stat for a course known for low scores. Matsuyama is an excellent value choice this week at Bay Hill and should be a major asset in your 2021 Arnold Palmer Invitational bets.

How to make 2021 Arnold Palmer Invitational picks

Also, the model is targeting five other golfers with odds of 20-1 or higher to make a strong run at the title, including a monster long shot. Anyone who backs these underdogs could hit it big. You can only see them here.
