James Riley Fridley (September 6, 1924 – February 28, 2003) was an American professional baseball player. During his Major League Baseball career, he was a backup outfielder, playing mostly at left field for three different teams between 1952 and 1958. Nicknamed "Big Jim", Fridley was listed at 6 feet 2 inches (1.88 m) and 205 lb (93 kg) and batted and threw right-handed. He was born in Philippi, West Virginia.
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).
In a three-season career, Fridley was a .248 hitter (105-for-424) with eight home runs and 53 RBI in 152 games, including 50 runs, 12 doubles, five triples, three stolen bases, and a .309 on-base percentage. In 123 outfield appearances, he posted a collective .982 fielding average (four errors in 228 chances). He also played in the minor league systems of the New York Yankees, Brooklyn Dodgers and Detroit Tigers.
