A league champion was determined at the end of every season. The Rochester Red Wings won 19 International League titles, the most in the league's history, followed by the Columbus Clippers and Toronto Maple Leafs (11). Since the introduction of the Governors' Cup in 1933, the most cup titles have been won by the Columbus Clippers (11), followed by the Rochester Red Wings (10) and Syracuse Mets (8). After the season, the IL champion played in the Triple-A National Championship Game against the Pacific Coast League champion to determine an overall champion of Triple-A baseball. The Columbus Clippers and Durham Bulls each won two national championships, more than any other IL teams.
