Before you set your PGA DFS lineups on sites like DraftKings and FanDuel for the 2019 WGC-FedEx St. Jude 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.

Earlier this month at the 3M Open, McClure rostered Bryson DeChambeau on FanDuel and DraftKings. The result: DeChambeau fired three rounds of 66 or lower on his way to a score of 20-under and a T-2 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 WGC-FedEx St. Jude 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: Hideki Matsuyama at $10,500 on FanDuel and $8,900 on DraftKings. McClure is also rostering Justin Rose ($11,000 on FanDuel, $9,500 on DraftKings), who's returned over 6x value on DraftKings in four of his last six starts.

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 them before locking in any lineups.
