Before you make any UFC Fight Night 158 picks, you need to see the predictions from SportsLine MMA expert Kyle Marley. He won the first-ever "ToutMaster" UFC betting contest sponsored by MMAOddsBreaker and is in contention to win this year's contest. He also appears regularly on multiple MMA betting and DFS shows. Over the past year, $100 bettors who have followed Marley's picks are up more than $21,000! 

At UFC 242 last weekend, Marley accurately predicted that Joanne Calderwood (+190) would upset Andrea Lee in a flyweight bout on the undercard. At UFC 241, Marley predicted that Nate Diaz (+110) would return from a three-year layoff to defeat Anthony Pettis by decision in a welterweight bout. Diaz came through with the upset, and Marley's followers picked up another easy winner. Anyone who has followed Marley is WAY UP.

We'll reveal one of Marley's UFC Fight Night 158 predictions here: He is picking Andrew Sanchez (+250) to pull the upset of Marvin Vettori (-300) in a middleweight bout on the preliminary card.

"Sanchez is a high-paced fighter and I think he is the better wrestler as well. I think Sanchez is a live dog here if he can strike at the higher pace and mix in his takedowns," Marley said.

Marley also has extremely confident picks locked in for Cerrone vs. Gaethje and every other bout on the UFC Fight Night 158 card. You ABSOLUTELY need to see his picks before making any of your own.
