MLB DFS: Optimal FanDuel, DraftKings tournament lineups, stacks, player pool for September 7 from a daily Fantasy pro

Before setting your MLB DFS lineups on daily Fantasy sites like DraftKings and FanDuel on Saturday, 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.

And on Friday, he was all over Astros shortstop Alex Bregman on both sites. The result: Bregman went 2-for-4 with a double, two runs scored, an RBI and a stolen base -- returning over 6x on investment for MLB DFS players on FanDuel. Anyone who has followed McClure has seen some huge returns. Now, McClure has set his sights on Saturday's slates.

One of McClure's top MLB DFS picks for Saturday is Los Angeles Angels designated hitter Shohei Ohtani at $2,900 on FanDuel and $4,400 on DraftKings. Another facet of McClure's optimal MLB DFS strategy Saturday is rostering Athletics third baseman Matt Chapman ($3,800 on FanDuel, $4,500 on DraftKings), who has a triple and a home run off Tigers starter Jordan Zimmermann in three career at-bats.

McClure is also targeting a player that is undervalued in DFS who is set to explode for huge numbers on Saturday. The stars are aligning for him to return tournament-winning 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.
