Midwest League
baseball league operating at the Class High-A level of Minor League Baseball in the Midwestern US
The Midwest League is a Minor League Baseball league established in 1947 and based in the Midwestern United States. A Class A league for most of its history, the league was promoted to High-A as part of Major League Baseball's 2021 reorganization of the minor leagues.
The Midwest League began as the Illinois State League (1947–1948) and then became the Mississippi–Ohio Valley League (1949–1955). In 1956, the Mississippi–Ohio Valley League was renamed the Midwest League. The circuit temporarily operated for the 2021 season as the High-A Central before reassuming its original moniker in 2022.
The Lansing Lugnuts, Wisconsin Timber Rattlers, and Quad Cities River Bandits are tied for the most Midwest League championships, with nine each.
History
The Midwest League directly evolved from two earlier leagues in the region. In 1947, the Class D Illinois State League (ISL) began operation with six Illinois teams: the Belleville Stags, Centralia Cubs, Marion Indians, Mattoon Indians, Mount Vernon Braves, and West Frankfort Cardinals. In 1949, the ISL changed its name to the Mississippi–Ohio Valley League after Marion moved their franchise to Kentucky and became the Paducah Chiefs. In 1954, the Mississippi-Ohio Valley League expanded, adding teams in Clinton and Dubuque, Iowa.
