The Northwest League is a Minor League Baseball circuit that operates in the Pacific Northwest region of the United States and Canada. Established in 1955, it primarily features teams affiliated with Major League Baseball clubs. The league is classified as a Class A Short Season league, meaning it typically plays a shorter schedule than other levels of minor league baseball. Teams in the Northwest League compete from June to September, culminating in a playoff series to determine the league champion. Notable teams include the Hillsboro Hops and the Everett AquaSox. The league serves as an important developmental stage for young players aiming to reach the major leagues.
