Before you enter a DFS tournament for MLB action on Sunday, May 27, you need to hear what professional DFS player Mike McClure has to say. McClure has more than $1 million in career winnings and has cashed huge on tournament rosters for NFL, NBA, NHL, golf and NASCAR in the past year.

When it comes to MLB, McClure is at his best. Recognized in the book "Fantasy Football (and Baseball) for Smart People: How to Turn Your Hobby into a Fortune" as a top MLB DFS player, McClure is off to a hot start this season thanks to some spot-on picks.

To close out last week, McClure rostered Dodgers pitcher Ross Stripling at $6,700 on FanDuel. The result: Stripling struck out 10 Padres over 6.2 innings with no earned runs allowed -- returning 60 FD points and 9x value. Anybody who had him in their lineup was well on their way to a profitable night.

For Sunday's loaded MLB DFS slate, McClure loves Tigers outfielder Leonys Martin at $2,900 on FanDuel and $3,400 on DraftKings.

Martin will benefit from a strong slugging environment in Detroit, where winds are expected to gust up to 8 mph and the temperature will hover near 90 degrees -- perfect long-ball weather. Roster him with confidence on Sunday.

McClure is stacking Martin with Tigers first baseman Victor Martinez, who is $3,100 on DraftKings and $2,200 on FanDuel.

Martinez, who batted clean-up on Saturday and rapped two hits, has the potential to be a big RBI producer on Sunday against White Sox starter James Shields, whose ERA is a lofty 4.62.

McClure is also targeting a player capable of putting up explosive numbers on Sunday. The stars are aligning for him to go for 30, even 40 points on FanDuel and DraftKings, all for a price that won't break the bank. This pick could be the difference between winning your tournaments and cash games or going home with nothing.
