Leo Durocher ( July 27, 1905 – October 7, 1991).
Leo Ernest Durocher was an American professional baseball player, manager, and coach. He played in Major League Baseball as an infielder. Upon his retirement, he ranked fifth all-time among managers with 2,008 career victories, second only to John McGraw in National League history.
Durocher appears in one episode of The Donna Reed Show in "Play Ball" (Season 7, Episode 3). Alex helps to organize a charity baseball game to benefit the hospital. When Willie Mays, Don Drysdale, and Leo Durocher show up it's no longer a game involving amateurs.
