This Hall of Famer excelled in football and baseball at both Wadsworth High School and the College of Wooster. An outstanding second baseman and outfielder, Dennison showed leadership traits early in his career. As player/manager, he led the Wadsworth Merchants to the 1960 Tri-County League title. While coaching baseball at Wadsworth and Elyria High Schools (1960-64), Jim played for Lorain Wolf Dry Goods and Elyrian Mustangs in the Lakewood League. In Akron, Dennison played for AA League Champion Krispy Kremes, P.O.C. Beer, Airmatic Valve, Weather Seal, and was player/manager for the champion Red Peppers from 1970-72. Dennison's amateur career was cut short when he was named head football coach at Akron U in 1973. However, he did enjoy a 17-year AA League career in which he was an All-Star in all three leagues. He played and hit over .300 in 14 of those seasons.
