Before you set your PGA DFS lineups on sites like DraftKings and FanDuel for the 2019 Pebble Beach Pro-Am, 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 Waste Management Phoenix Open, McClure built his FanDuel lineups around Justin Thomas. The result? Thomas fired three rounds of 68 or better on his way to a score of 14-under par and a third 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 Pebble Beach Pro-Am and has revealed his optimal DFS lineups. They're a must-see for any PGA DFS player.

One of McClure's favorite players this week: Dustin Johnson ($12,400 on FanDuel, $11,400 on DraftKings), who's won this event twice in his career and is coming off an impressive victory last week at the Saudi International. He's an almost sure-fire bet to be near the top of the leaderboard come Sunday.

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

So what 2019 Pebble Beach Pro-Am lineups should you enter on DraftKings and FanDuel? And which undervalued player is a must-roster? ...
