James Johnston (baseball owner)

James Martin Johnston (December 8, 1895 – December 28, 1967) was the co-owner of the Washington Senators of the American League with James Lemon from 1963 until his death in 1967. In 1963, Johnston and Lemon purchased the franchise from Elwood Richard Quesada. His estate and James Lemon sold the team to a group of Minnesota buyers in 1968.
