After the Boston Red Sox came back to defeat the Los Angeles Dodgers in Game 4 of the World Series to take a commanding 3-1 series lead, there's only one more guaranteed shot at big money in MLB DFS tournaments and cash games this season. Game 5 is on Sunday and Clayton Kershaw will take on David Price with hopes of sending the series back to Boston. The perfect MLB DFS lineups could be worth thousands with FanDuel offering a $25,000 World Series Special and DraftKings offering a $35,000 Extra Inning tournament. So before you make your MLB DFS picks, be sure to check out what DFS expert Mike McClure has to say. McClure has won nearly $2 million playing DFS in his career and his picks have led followers to big cashes all season.

And 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 rolling this season, already producing multiple tournament lineups that have won big thanks to some spot-on picks.

In Game 4 of the World Series on Saturday, McClure rostered Dodgers infielder Justin Turner. The result? Turner went 3-for-4 with a double, a walk and a run scored. Anybody who had him in their lineup was well on the way to a profitable day. 

For Sunday night's single-game slate featuring Game 5 of the World Series, McClure is banking on Red Sox first baseman Steve Pearce.

Pearce had a heroic Game 4, hitting a home run and a bases-loaded double that drove in three runs. He finished 2-for-4 with 4 RBI, which helped spark a Red Sox comeback to give Boston a chance to close out the series on Sunday. He's been timely all postseason and has a chance to be a big DFS producer against lefty Clayton Kershaw on Sunday night. During the regular season, Boston's offense ranked eighth in the American League with an OPS of .719 against left-handed pitching.

McClure is stacking Pearce with Red Sox outfielder Mookie Betts.

Betts has reached safely in 11 of 13 postseason games this season and even though he only has four extra-base hits in 58 at-bats during the playoffs, he always has the potential for multiple extra-base hits on any given night. Be sure to lock Betts in as a top MLB DFS pick on Sunday.

McClure is also targeting a player with a dream matchup on Sunday. The stars are aligning for him to go for 30, even 40 points, and he comes at a great price. The pick could be the difference between cashing in or going home with nothing.
