The Casper Rockies of Casper, Wyoming, played seven seasons in the Pioneer League. For that entire time, they were a Rookie Advanced level affiliate of the Colorado Rockies. The team began following the 2000 season, when the Butte Copper Kings moved one state south from Montana and became the first affiliated minor league team to play in Wyoming in the modern era.
The C-Rockies were a COTOB identity, and their branding materials hewed close to that of their parent club to the south. Uniforms were very similar to Colorado’s, with variations including pinstripes and black pullovers. The primary logo featured a purple peak above the team name–with Casper spelled in cursive with a wide, oversized C and Rockies rendered in Colorado’s font. While this full logo (minus the Rockies) was often used as the cap logo, they also had a simplified logo with an R inside the wide C, that looked suspiciously similar to the NHL’s Montréal Canadiens’ logo. The team colors of black, silver, and purple were used interchangeably on cap crowns, bills, etc.
Despite only existing for seven years and playing at the bottom rung of the minors, Casper had a good pocket of future MLB contributors. Though there are no standout stars, it’s a deep bench featuring the likes of Ubaldo Jimenez, Jayson Nix, Pedro Strop, Seth Smith, Dexter Fowler, Everth Cabrera, and Jhoulys Chacin.
With about 50,000 residents, Casper was always a little bit of a stretch for being able to field an affiliated team. After the 2007 season, in an effort to boost brand viability, the team hired the Plan B (now Brandiose) design company to give the team a unique identity. The company delivered in spades, and changed the Casper Rockies into the iconic Casper Ghosts. Even that wasn’t enough to keep affiliated ball in Casper, though, and the Colorado Rockies’ ownership group scooped up the Ghosts and moved them to the Centennial State, where they now play as the Grand Junction Rockies.
