Before you set your DFS lineups on DraftKings or any other fantasy site for the STP 500 on Monday, you need to hear what Mike McClure has to say. 

McClure is a predictive data engineer and a DFS pro with more than $1 million in career winnings. He's crushed his DFS selections in multiple sports recently, including producing multiple tournament rosters that have cashed huge in NFL, NBA, golf and NHL in the past year.

He's off to fast start in NASCAR as well, locking Kyle Larson in his DraftKings lineup last week. The result? Larson finished second at the Auto Club 400, and anybody who had him in their lineup was well on the way to a profitable Sunday.

For the STP 500 at Martinsville, McClure loves Clint Bowyer as a value play at $8,300 on DraftKings. If you roster him, you'll have plenty of room to add a big star like Joey Logano ($9,500 on DraftKings), who is one of the top contenders this weekend.

McClure is also targeting a driver who is regularly finishing in the top five this year and has an elite record at Martinsville. He's in prime position to make a run at the checkered flag, and he comes at a price that won't break the bank. This pick could be the difference between cashing in your tournaments or going home with nothing....So what is the optimal NASCAR DFS tournament lineup for the STP 500 on Monday? Join SportsLine now to see DFS millionaire Mike McClure's complete optimal tournament lineups DraftKings, and cash big on Monday!
