Before you set your PGA DFS lineups on sites like DraftKings and FanDuel for the 2020 Arnold Palmer Invitational, you NEED to see 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.

Last year at the Arnold Palmer Invitational, McClure rostered Sungjae Im and Tommy Fleeetwood on FanDuel and DraftKings. The result: They both 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. They're a must-see for any PGA DFS player.

One player McClure is rostering this week: Tyrrell Hatton at $8,100 on DraftKings and $9,900 on FanDuel. McClure's optimal PGA DFS strategy also includes rostering Jason Day ($10,900 on FanDuel, $9,100 on DraftKings), who won this event in 2016. 

McClure is also targeting an undervalued player who's primed to blow up this week, giving you a HUGE return! Picks like these could be the difference between winning your PGA DFS contests or going home with nothing. You ABSOLUTELY need to see who it is before locking in any lineups.
