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

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.

Cleveland left-hander Parker Messick will make his major league debut in the heat of a playoff race. The Guardians announced they will promote Messick, their second-round pick in the 2022 draft, to start the final game of a three-game set against the Arizona Diamondbacks on Wednesday afternoon in Phoenix.
