Before you set your NASCAR DFS lineups for Sunday's 2019 STP 500 at Martinsville, you'll want to see what DFS expert Mike McClure has to say. McClure is a predictive data engineer and a DFS pro with nearly $2 million in career winnings. He's crushed his DFS selections in several sports recently, including producing multiple tournament rosters that have cashed huge.

He was all over his NASCAR picks for last week for the Auto Club 400, locking Kurt Busch in his FanDuel and DraftKings lineups. The result: Busch surged to his second consecutive win and anybody who built their lineup around him was well on their way to a HUGE day.

For the 2019 STP 500 on Sunday, we can tell you McClure is banking on Denny Hamlin at $13,000 on FanDuel and $9,400 on DraftKings. His optimal NASCAR DFS strategy also involves rostering Jimmie Johnson ($9,900 on FanDuel, $8,000 on DraftKings), who has nine career wins at Martinsville, more than any other active driver. 

McClure is also targeting a value driver with a strong track record at Martinsville. He's in prime position to make a run at the checkered flag and comes at a price that won't break the bank. This pick could be the difference between cashing HUGE in your tournaments and cash games or going home with nothing.
