Pitcher Walt Masterson was discovered playing semi-pro ball by scout Joe Cambria and made his big league debut with the Washington Senators as an 18-year-old in 1939. He was the first payer born in the 1920s to appear in a major league game. After four seasons with the club, splitting time between the bullpen and the rotation, he entered the Navy in September 1942. Following his discharge in July 1945, he returned to the Senators.
