The latest product of the Guardians' pitching factory is making his first MLB start today. Here's what to know about him.

Cleveland Guardians newly promoted left-handed starter, Parker Messick had an outstanding debut against the Arizona Diamondbacks.

Keith Law of the Athletic wrote on Messick this spring: “Messick is a stout-bodied lefty with fringy stuff and a lot of deception, working with a 55 changeup and average velocity” ranking him 11th in the Guardians’ system and projecting him as a fourth starter.
