Major League Baseball and the Pioneer League jointly announced today that the Pioneer League has been designated a “Partner League” of MLB. Starting in 2021, the Pioneer League will transition from affiliated status to an independent professional MLB Partner League that continues to provide high-quality baseball to the states of Idaho, Montana, Utah and Colorado. All eight members of the Pioneer League – the Billings Mustangs, the Grand Junction Rockies, the Great Falls Voyagers, the Idaho Falls Chukars, the Missoula Paddleheads, the Ogden Raptors, the Northern Colorado Owlz and the Rocky Mountain Vibes – will continue participating in the league and will maintain their existing team names and brands.
