I don’t need to tell you who Corey Kluber is. You probably remember him as one of the most dominant starting pitchers in MLB since 2013. Perhaps his winning of the 2014 AL Cy Young over Félix Hernández is a wound that still has yet to heal after six years (although, I remain adamant that Kluber was the rightful recipient). Regardless, I think a strong fit exists between Kluber and the Mariners.
For starters, there exists plenty of downside, and the downside is that Kluber pitches one inning on the year.
