5 players
5 players won the Cy Young in a season with the Cleveland Guardians. Corey Kluber did it the most, twice (2014, 2017). On a roster now: Shane Bieber.
A winner counts for a club when he played for it in the season he won, the Immaculate Grid's rule. Award lists from Wikipedia. Every season since 1876 is on file. A season split between two clubs is filed as one combined line and counts for neither.
