Before setting your MLB DFS lineups on daily Fantasy sites like DraftKings and FanDuel on Tuesday, you NEED to hear what Mike McClure has to say. McClure is a DFS pro with nearly $2 million in career winnings.

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," McClure's proprietary MLB DFS projection model simulates each game 10,000 times, taking factors such as matchups and recent results into account. This allows him to find the best values on every site.

He got off to a HOT start in 2019, producing lineups on SportsLine that have returned as much as 30x. He also finished in the top 1 percent of tournaments four times and the top 0.1 percent of tournaments twice in the first half of the season. He cashed huge in three consecutive tournaments in mid-June, which included a top 2 percent finish when his DraftKings lineup generated a whopping 185.9 points. He also had an optimal lineup on FanDuel that cashed 8x for followers the Friday before the All-Star break.

Then on Monday, he was all over Athletics left fielder Khris Davis on both sites. The result: Davis went 3-for-5 with a home run and two RBIs -- returning around 38 points and 16x value on FanDuel. Anyone who has followed McClure has seen some HUGE returns. Now, McClure has set his sights on Tuesday's slates.

One of McClure's top MLB DFS picks for Tuesday is Red Sox third baseman Rafael Devers at $4,500 on FanDuel and $5,800 on DraftKings, who is hitting .319 on the road this season with 17 doubles and 16 home runs. Another facet of his optimal MLB DFS strategy is rostering Athletics left fielder Chad Pinder ($2,500 on FanDuel, $3,400 on DraftKings).

McClure is also targeting an undervalued player who is set to EXPLODE for huge numbers on Tuesday. The stars are aligning for him to return huge value and he comes at a price that won't break the bank. This pick could be the difference between cashing in BIG or going home with nothing.
