Professional baseball has been played in
Cedar Rapids since 1890. Cedar Rapids teams have been a member of various leagues preceding the current franchise. They have been a member of the
Western League (1934–1937),
Mississippi Valley League (1922–1932),
Central Association (1913–1917),
Illinois–Indiana–Iowa League (1901–1909, 1920–1921, 1938–1942),
Western Association (1896–1899), Eastern Iowa League (1895) and the
Illinois–Iowa League (1890–1891). Cedar Rapids teams also had numerous nicknames prior to the current franchise: Cedar Rapids Raiders (1934–1942), Cedar Rapids Red Raiders (1963–1964), Cedar Rapids Bunnies (1904–1932), Cedar Rapids Rabbits (1896–1903) and Cedar Rapids Canaries (1890–1891). The moniker of "Rockets" was chosen via a name-the-team contest. After the 1949 season, the Rockets moved to the
Three-I League to replace the
Springfield, Illinois team that the league had just dropped. Cedar Rapids played in the Three-I League until it folded after the 1961 season, at which point they moved to the Midwest League along with the
Fox City Foxes and the
Burlington Bees. When Cedar Rapids entered the Midwest League in 1962, the franchise switched back to the Red Raiders (1962–1964) nickname. Subsequently, the team used the name of the major league franchise it affiliated with: the
Cardinals (1965–1972), the
Astros (1973–1974), the
Giants (1975–1979), and the
Reds (1980–1992). The team adopted the current "Kernels" nickname before the 1993 season. On the field, the franchise won
Midwest League championships in 1988, 1992, 1994, and 2023. In conjunction with
Major League Baseball's restructuring of Minor League Baseball in 2021, the Kernels were organized into the
High-A Central. In 2022, the High-A Central became known as the Midwest League, the name historically used by the regional circuit prior to the 2021 reorganization. ==Ballpark==
