Before setting your MMA DFS lineups on sites like DraftKings and FanDuel for UFC Fight Night: Lewis vs. Oleinik on Saturday, you NEED to see what Mike McClure has to say.

McClure is a predictive data engineer and a DFS pro with almost $2 million in career winnings. He's crushed his DFS selections lately, producing tournament rosters that have cashed huge in multiple sports over the past few years. 

At UFC Fight Night: Brunson vs. Shahbazyan last Saturday, McClure was all over Vicente Luque as one of his top picks. The result: Luque scored a second-round knockout win over Randy Brown, and anybody who followed McClure's advice was well on their way to building a winning lineup. Now, McClure has set his sights on Saturday's UFC Fight Night: Lewis vs. Oleinik card at the UFC Apex Facility in Las Vegas. 

For UFC Fight Night: Brunson vs. Shahbazyan, we can tell you McClure is high on Derrick Lewis at $8,700 on DraftKings and $21 on FanDuel. Part of McClure's optimal UFC DFS strategy also includes rostering Tim Means ($7,900 on DraftKings, $16 on FanDuel), a 17-fight UFC veteran who lands 45 percent of his significant strikes.

McClure is also targeting a value fighter who is a must-play because his fight is a HUGE mismatch! This pick could be the difference between cashing huge in MMA DFS or going home with nothing.
