The Eugene Emeralds, formerly of the Northwest League and now in High-A West, had the NwL's worst overall record in 2018 but made the playoffs as a wild card - and won out for the crown!
MLB's 2021 Minor League Reorganization raised the Ems, and most of the NwL, two levels and moved the Ems under the San Francisco Giants' umbrella.
Early editions of the Emeralds played at Bethel Park, but the expansion of 1969 that begat the Seattle Pilots bumped the Pacific Coast League's Seattle Angels team to Eugene, where they moved to Civic Stadium. The NwL returned in 1974, again choosing Civic. They moved into P.K. Park, originally built when the University of Oregon resumed its baseball program, in 2010. The old yard fell victim to arson in June 2015; the August night its old team commemorated it, four Ems pitchers hurled a combined no-hitter.
The Ems play Copa de la Diversión Hispanic engagement campaign games as Monarcas de Eugene (Eugene Monarchs, which can either refer to emperors or to monarch butterflies).
