Corey Kluber's Stats, Metrics, Game Logs, Projections & Rankings

Right-hander Corey Kluber officially announced his retirement from professional baseball on Friday. The 37-year-old starter was never really the same pitcher once he left the Cleveland Guardians, and injuries ended up derailing his career the last several seasons. He appeared in only 15 games (nine starts) for the Boston Red Sox in 2023 and had a rough 7.04 ERA (7.11 FIP), a 1.64 WHIP, one save, 21 walks and 42 strikeouts in 55 innings pitched. In his prime, though, Kluber was one of the better pitchers in the game and he made three straight All-Star appearances from 2016-18. Kluber also won two American League Cy Young awards in his 13-year MLB career, ultimately finishing with a 3.44 ERA (3.23 FIP) and 1.13 WHIP with a 25.8 percent strikeout rate in 1,641 2/3 innings pitched with Cleveland, the Texas Rangers, New York Yankees, Tampa Bay Rays and Red Sox.
