Watch Now: Sungjae Im Wins First Tour Event (1:20)

Before you set your PGA DFS lineups on DraftKings or FanDuel for the 2020 Arnold Palmer Invitational, you need to hear what Mike McClure has to say. McClure is a DFS pro with nearly $2 million in career winnings, and he's been red-hot on his PGA Tour picks this season. McClure is also a predictive data engineer at SportsLine who uses a powerful prediction model that simulates every tournament 10,000 times, taking factors like statistical trends, past results and current form into account. This allows him to find the best PGA DFS values and create optimal lineups that he shares only over at SportsLine. They're a must-see for any PGA DFS player.

Last year at the Arnold Palmer Invitational, McClure rostered Sungjae Im and Tommy Fleeetwood on FanDuel and DraftKings. The result: Both players tied for third and anybody who had them in their lineup was well on their way to a huge weekend.

Now, McClure has set his sights on the 2020 Arnold Palmer Invitational and revealed his optimal PGA DFS lineups. You can only see them at SportsLine

Top Arnold Palmer Invitational DFS picks

One PGA DFS pick McClure is rostering for the Arnold Palmer Invitational 2020: Tyrrell Hatton at $8,100 on DraftKings and $9,900 on FanDuel.

Hatton enters this week's event having finished inside the top 15 in each of his last three starts on the PGA Tour, which includes a sixth place finish at the WGC-Mexico Championship. Hatton enters this week's tournament hitting the ball extremely well off the tee, averaging 328 yards per drive this season. His ability to drive the ball deep into the fairway allows him to use his short irons to approach the green. That lethal combination has allowed Hatton to hit over 76 percent of greens in regulation, which should allow him the opportunity to rack up points this week at Bay Hill. Lock him into your PGA DFS picks and look for a big return this week at the Arnold Palmer Invitational.

McClure's optimal PGA DFS strategy also includes rostering Jason Day at $10,900 on FanDuel and $9,100 on DraftKings. 

Day won this event in 2016 and the 32-year-old has all the tools needed to find himself in contention again this year. Day will enter this week's event ranked first on the PGA Tour in strokes gained: around the green (1.256) and ninth in shots gained: tee-to-green (1.459). His familiarity with this event coupled with his confidence from past experiences make him an extremely strong PGA DFS play at the 2020 Arnold Palmer Invitational.

McClure is also targeting an undervalued player who's primed to blow up this week, giving you a huge return on both sites. Picks like these could be the difference between winning your PGA DFS contests or going home with nothing.
