The Dodgers must have been relieved to see the back of Johnny Mize when the Giants shipped him out in August 1949. The Hall of Fame first baseman had spent all of his career in the National League until he left the Giants. He put up a 1.044 OPS against Brooklyn in his time with the Cardinals and Giants. That was a higher OPS than he had against any other team, and did so in nearly 900 plate appearances.
Unfortunately for the Dodgers, he didn’t go very far.
After six years with the Cardinals, Mize was traded to the Giants in December 1941.
