There may be some value on Josh Naylor's walks prop. THE BAT X is projecting him to record 0.39 walks, and oddsmakers are implying 0.27. The model believes there is a 33% chance he records at least 1 walk, so there is value on the over at +321. This play is good down to at least +235. Love THE BAT X?
