On Sunday, left-hander Parker Messick had his last tune-up before the postseason. The Cleveland Guardians ace allowed one run in three innings in the regular-season finale against the Kansas City Royals.
The left-hander will, in all likelihood, take the ball for either Game 1 or 2 against the winner of the Chicago White Sox-Houston Astros series this weekend. And to be fair, he has earned the right to lead the Guardians’ staff after his brilliant 2026 campaign.
Messick started the year as a rotation hopeful in spring training. Not only did he win a spot, but he became an unquestioned ace and one of the top pitchers in the American League.
What the southpaw did this year was beyond any fan’s imagination. His total season output is up there with some of the most impressive rookie campaigns for a starter.
“Parker Messick finishes the 2026 regular season with a 2.56 ERA & 193 SO. The only rookie P with better numbers in a season since 1901 are: 1901 Christy Mathewson (2.41 ERA, 221 SO), 1910 Russ Ford (1.65, 209), 1995 Hideo Nomo (2.54, 236),” Potosky posted.

Matthewson is a legend of the game and a Hall of Famer, and Nomo was one of the best Japanese pitchers of his era. That’s some pretty good company right there for Messick.
That’s incredibly impressive for a guy with average fastball velocity. More often than not, the common denominator for dominant ERA and strikeout guys is a high-octane fastball, usually in the triple digits. This is definitely not the case with Messick, though.
Messick’s four-seamer is in the 93-96 mph range most of the time, but with excellent extension and ride, the offering has a devastating effect on hitters waiting for his incredible changeup. The lefty, on top of all that, has superb command of both pitches and other excellent secondaries to round out his repertoire.
The new Guardians’ ace wrapped up his first full season with a 12-9 record, a 2.56 ERA, a 3.07 FIP, 4.9 fWAR, and 193 punchouts in 186.1 innings. Cleveland hasn’t had such a dominant starter since 2020 Shane Bieber, the year he won the AL Cy Young Award.
He is a man on a mission now: leading the staff that gives the Guardians their first World Series title since 1948.
