Preview for Sunday, September 27, 2026. Schedule and player information can change.

Cleveland Guardians at Kansas City Royals

Cleveland Guardians travel to face the Kansas City Royals with Parker Messick taking the mound for the Guardians against Daniel Lynch IV for the Royals. Messick has been the stronger performer this season, posting a 2.55 ERA and a 3.14 FIP across approximately 183.3 innings pitched, while Lynch IV carries a 4.13 ERA and a 4.40 FIP over roughly 80.7 innings pitched. That gap in both ERA and FIP suggests Messick has been the more effective run-preventer of the two starters this year.

Looking at the team-level numbers, the Royals actually hold a slight offensive edge with a WP-estimated wOBA of 0.311 compared to the Guardians' 0.305. On the run-prevention side, though, Cleveland's team ERA of 3.77 and FIP of 3.87 are both notably better than Kansas City's 4.79 ERA and 4.81 FIP, giving the Guardians a clear overall advantage in pitching depth beyond just the starters.

Injury-wise, the Guardians have Jonah Advincula listed on the 7-Day IL, Robert Arias listed on the 60-Day IL, and Emmanuel Clase listed with a status of Out, while the Royals have Luinder Avila, Ryan Bergert, and Christian Chamberlain all listed on the 60-Day IL. Taken together, the pitching figures favor Cleveland, with Messick's markedly better ERA and FIP paired with the Guardians' stronger team ERA and FIP giving them the more complete case on the mound, even though Kansas City's team wOBA is slightly higher.
