The Northwest League is a Minor League Baseball league that operates in the Northwestern United States and Western Canada. A Class A Short Season 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 league operated as the High-A West in 2021, then resumed its original moniker in 2022.
The Northwest League (or the Northwestern League) has existed in various forms since 1890, and has been in its current incarnation since 1955.[1] The current NWL is the descendant of the Western International League (WIL), a Class B league from 1937 to 1951 (with a stoppage during World War II) and Class A from 1952 to 1954. The league reformed as the Northwest League and dropped to Class B for the 1955 season.[2] [3] The WIL had ten teams in its final season, with four in Canada.
In 1955, the Northwest League was formed, with seven charter teams: Salem Senators, Eugene Emeralds, Yakima Bears, Spokane Indians, Tri-City Braves, Wenatchee Chiefs, and Lewiston Broncs.[4] [5] The league switched to the short season schedule in 1966;[6] between then and 1982, the NWL fluctuated between four, six, and eight clubs. In 1983, the league returned to an eight-team circuit, which it maintained through 2019.
The start of the 2020 season was postponed due to the COVID-19 pandemic before ultimately being cancelled on June 30.[7] [8] As part of Major League Baseball's 2021 reorganization of the minor leagues, the Northwest League was promoted to High-A, reduced to six teams, and renamed the "High-A West" for the 2021 season.[9] The two dropped teams were the Boise Hawks and Salem-Keizer Volcanoes. Following MLB's acquisition of the rights to the names of the historical minor leagues, the High-A West was renamed the Northwest League in 2022.[10]
