Mayers allowed a whopping nine runs on eight hits and two walks across just 1.1 innings in his big league debut Sunday against the Dodgers. He did manage to strike out one batter.

The rookie couldn't have gotten off to a worse start, as he allowed the first three men he faced to reach base before Adrian Gonzalez stepped up and smacked a grand slam to center. Mayers eventually got out of the first after allowing six runs and returned for the second, although he allowed the Dodgers to string a rally together and was chased after three more men crossed the plate. The club was expected to send Mayers down after Sunday's spot start all along, and his ERA of 60.75 should remove any doubt from the decision.
