A 1958 graduate of Frederick High School who distinguished himself as a varsity baseball and basketball player, Don Loun became interested in pitching while playing for Buckeystown in the Tri-County League 1957–1961, began showing promise, and was signed by the Washington Senators. In just four years, he moved from Class D ball to AA with York, PA; and then to AAA with Toronto and Hawaii. On September 23, 1964, he pitched for the Washington Senators, winning a 5-hit shut-out over the Boston Red Sox. He lost the second game to Boston at Fenway Park 2-0 on October 2nd. Loun remained in baseball with AAA teams until a shoulder injury in 1969 ended his career. Loun was a gifted left-hander who earned his moment in the sun.
