The Medicine Hat Mavericks are a collegiate summer baseball team that plays in the Western Canadian Baseball League. Based in Medicine Hat, Alberta, Canada, they began play in 2003.^[1] They currently play at Athletic Park, a 2200-seat diamond located on the banks of the South Saskatchewan River.^[2]

The Mavericks were founded in 2003 by Jim and Carol Hern, a pair of local ranch-owners, as an expansion team alongside the Calgary Dawgs in the then Western Major Baseball League (now the Western Canadian Baseball League).^[3][4] The team filled the vacancy left at Athletic Park when the Toronto Blue Jays ended their affiliation with the Medicine Hat Blue Jays of the Pioneer League in 2002.^[5][3]

In 2009, Greg Morrison, a local business owner and former prospect of both the Toronto Blue Jays and Los Angeles Dodgers became owner and general manager of the Mavericks, purchasing the team from the Hern family.^[3][6][7]

Throughout their history, the Mavericks have won the League Championship three times, during their inaugural season in 2003, then in 2014, and in 2018.^[8] In 2023, the Mavericks would make it to the championship finals against the Okotoks Dawgs, losing 13–5 in the third and deciding game.^[9][10]
