Donald Ray (Don) Elston (April 6, 1929 – January 2, 1995) was a pitcher in Major League Baseball who played for the Chicago Cubs (1953, 1957, 1958–64) and Brooklyn Dodgers (1957). Elston batted and threw right-handed. He was born in Campbellstown, Ohio.A hard-thrower pitcher, Elston played for perennially weak Chicago Cubs teams for most of his nine-year major league career. He began as a starter, but after switching to the bullpen, he became one of the best relievers in the National League.
