Northwest League

The Northwest League of Professional Baseball (or simply the Northwest League or NWL) is a Class A Short Season minor league in the northwest United States and western Canada. The NWL's short season starts in mid-June, after major league teams have signed their amateur draft picks to professional contracts, and ends in early September. All eight teams are affiliated with a major league team.

The Northwest League (or the Northwestern League) has existed in various forms since 1890, and has been in its current incarnation since 1955. 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.

The WIL had ten teams in its final season, with four in Canada. The six U.S. cities plus Eugene were the seven charter teams of the Northwest League in 1955: Salem Senators, Eugene Emeralds, Yakima Bears, Spokane Indians, Tri-City Braves, Wenatchee Chiefs, and Lewiston Broncs. During its fiftieth season in 2004, five of the seven original cities were in the league. The Northwest League switched to the short season schedule in 1966, with only four teams.

Champions
League champions have been determined by different means since the Northwest League's formation in 1955. Except for 1956, 1960, and from 1966 to 1973, all seasons have ended with playoffs to determine a league champion.

The Spokane Indians and Yakima Bears have each won 8 championships, the most among all teams in the league, followed by the Boise Hawks and Eugene Emeralds (6).
