After finishing high school, Fridley worked briefly for the FBI and later served in the U.S. Army for four years during World War II. Following his service discharge, he attended West Virginia University on a football scholarship, playing both for the WVU baseball and football teams. He was signed by the Cleveland Indians as a free agent in 1948, playing for them one year (1952) before joining the Baltimore Orioles (1954) and Cincinnati Redlegs (1958). His most productive season came in 1954, when he posted career-highs in games (85), runs (25), RBI (36) and extrabases (17).
