Before you set your PGA DFS lineups on sites like DraftKings and FanDuel for the 2019 Tour Championship, 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.

Last week at the BMW Championship, McClure rostered Patrick Cantlay on FanDuel and DraftKings. The result: Cantlay fired four rounds of 68 or under on his way to score 22-under and a second-place finish. Anybody who had him in their lineup was well on their way to a HUGE weekend.

Now, he's set his sights on the 2019 Tour Championship and revealed his optimal PGA DFS lineups. They're a must-see for any PGA DFS player.

One player McClure is rostering this week: Rory McIlroy at $11,400 on FanDuel and $10,600 on DraftKings. McClure's optimal PGA DFS lineup also includes Dustin Johnson ($10,100 on FanDuel, $8,400 on DraftKings), who's tied with McIlroy and Tiger Woods for the most career wins in the FedEx Cup Playoffs with four.

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. You ABSOLUTELY need to see who it is before locking in any lineups.
