History
After the 2020-21 Minor League Baseball reorganization left the Salem-Keizer Volcanoes (hitherto members of the Northwest League as the San Francisco Giants' A Short-Season affiliate) without an affiliation, the Volcanoes resolved that they would play in 2021 nonetheless, with further information to come. On January 26, 2021, it was announced that the Volcanoes ownership would be forming their own independent baseball league, the Mavericks League.

The league has four teams based in the Salem Metropolitan Statistical Area, with all games being played at Volcanoes Stadium in Keizer, Oregon. It is aimed at top-level undrafted and released players, as well as high-level collegiate and former Volcanoes players seeking to rejoin the MLB affiliated minor league ranks.

In addition to the Volcanoes, the league will feature the Campesinos de Salem-Keizer (previously the Volcanoes' Copa de la Diversión alter-ego) as well as the revival of the Portland Mavericks (an infamous independent Northwest League team which played from 1973 to 1977) and the Salem Senators (a name used by numerous Northwest League teams based in Salem throughout the 20th century).
