German Marquez is allowing nearly 50% fly balls, which may work in Petco Park but at nearly 7,400 ft elevation, he could run into trouble. We have thinner air than in Denver and a higher altitude, so giving up hard hit fly balls and barrels isn't a recipe for success here. Furthermore, it's the lefties that Marquez has struggled with, allowing 12 hits (3 HR) and four walks in just 8.1 innings thus far. This DBacks lineup will feature six lefties tonight, five in the first six batters of the order, so even if he makes it through a couple times unscathed, is pushing Marquez through all those lefties a third time the best move? At plus odds I'll take the under.
