my OM Method today has us on the Chicago cubs with Hammel.
You will see my formula below for the power index marginal play based on cubs and pirates series from previous outings
OM Formula = Pirates Starters Piting Worley < = 4.00 era vs Cubs ^ Runs Scored { ob % .693 }
Play cubs factoring Runs Scored J Arrieta { < = less than 6.00era } > Runs scored opposition
Lock in Cubs- Marginal Win = Cubs % ^play
