The Expedition League is a collegiate summer baseball league in the Great Plains region of the United States and Canada. The league was founded in May 2017 in Rapid City, South Dakota, by businessman Steve Wagner, who also serves as president. The league featured eight teams in its inaugural season that began in May 2018.[1] It added the Wheat City Whiskey Jacks and the Fremont Moo for the 2019 season.[2] It currently has 10 teams as of the 2019 season.
The Rapid City Jackalopes, originally announced for the 2020 season,[3] were described in early 2020 as being "at least one more year away" due to the lack of a suitable stadium.[4] The Hub City Hotshots have suspended operations for the 2020 season and the city of Aberdeen, South Dakota has terminated the contract for use of Fossum Field.[5] In December 2019, the Sioux Falls Sunfish announced that the team would begin play in the 2020 season,[6] playing at Karras Park Home of Ronken Field in Sioux Falls, South Dakota.[7]
