In honor of the Explorers making the 2024 playoffs, here's my official guide to the Sioux City Explorers baseball team: Sioux City Explorers basics The Sioux City Explorers baseball team is part of the West Division of the American Association of Professional Baseball, which is an MLB affiliate league, and they have had dozens of players called up to the majors! The team colors are red and black, and the team mascot is Slider, a black Newfoundland dog. The team nickname is "the Xs" and their team logo is a block letter X with a baseball flying in front of it. Sioux City Explorers Team History The Sioux City Explorers have been in Sioux City since the team started in 1993 (which is why Slider's jersey has a 93 on it!) They played as part of the Northern League from 1993 to 2005 when they joined the AAPB. They have won their division championship several times but have yet to win the league championship.
