Before studying matchups and entering an MLB DFS contest on Sunday, first be sure to check in with Mike McClure. He's a professional DFS player who has won almost $2 million in his career, and his optimal MLB DFS lineups, advice and player pool at SportsLine can help you make all the right calls.

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 Friday, he was all over Rockies shortstop Trevor Story on FanDuel. The result: Story went 2-for-5 with a home run and two runs scored -- returning around 6x value and 28 points. Anyone who has followed McClure has seen some HUGE returns. Now, McClure has set his sights on Sunday's slates.

One of McClure's top MLB DFS picks for Sunday is Yankees outfielder Aaron Judge. Part of McClure's optimal MLB DFS strategy for Sunday also includes rostering Twins second baseman Luis Arraez, who hit .297 with 27 hits and 14 RBIs in August. 

McClure is also targeting an undervalued player who is set to EXPLODE for huge numbers on Sunday. 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.
