MLB DFS players entering tournaments, cash games, or 50-50s on FanDuel or DraftKings for Memorial Day's MLB DFS slate have plenty of tough choices to make. Investing in Mookie Betts, Mike Trout or Nolan Arenado is a great way to guarantee production, but all three come with a hefty price tag on both sites. They'll eat up a large portion of your MLB DFS salary cap right off the bat, so making the right call on the value of players such as them will be critical when evaluating Memorial Day's MLB DFS slate. And before you enter an MLB DFS tournament like the $200K MLB Memorial Monster on FanDuel or the $175K Tech for Heroes Extra Inning on DraftKings, first be sure to check in with Mike McClure. He's a professional DFS player with almost $2 million in career winnings and his top picks, optimal lineups and MLB DFS advice can help you build the perfect roster.

Part of McClure's optimal MLB DFS strategy for Monday includes targeting Reds outfielder Jesse Winker at $2,500 on FanDuel and $4,000 on DraftKings. The Reds have scored 31 runs over their last four games, and Winker has been a major contributor to Cincinnati's offensive outburst. In fact, Winker has recorded five hits, five runs scored and one RBI in his last four outings. Lock him in as one of the top overall MLB DFS plays on Monday.

He's stacking him with teammate Joey Votto at $2,900 on FanDuel and $3,700 on DraftKings. Votto is hitting .409 with nine hits, four runs scored and one RBI over the last week and he has a great chance to produce big numbers again on Monday against Pirates starter Nick Kingham, who has a massive 8.76 ERA. Lock him in your MLB DFS lineups and look for a big return against Pittsburgh on Monday.

McClure is also targeting an undervalued player who is set to explode for huge numbers on Monday. The stars are aligning for him to return huge value and he comes at a lower price than you would expect. This pick could be the difference between cashing in big or going home with nothing.
