With the PCL as a major league, obviously there's a need for a new top level minor league. I thought about raising the Cal League but it made more sense to reorganize into a new western league.
Most of these teams are existing or recently-departed PCL teams. The links are to posts where someone posted designs based on SFGiants58's concepts, and the boldface are designs I'll post.
Colorado Springs Sky Sox: Vancouver Salmon Kings
Oakland Oaks: Salt Lake Bees
Tacoma Rainiers: Seattle Rainiers
San Jose Churros: San Francisco Seals
Reno Aces: Portland Beavers
Oklahoma City 89ers: Sacramento Solons
San Antonio Missions: Hollywood Stars
Phoenix Crotalos: San Diego Padres
Las Vegas Lizards
: Los Angeles Angels
Albuquerque Isotopes: Denver Bears
(I know the Texan big league teams are in the MLB, but it was easier to keep the Texas League as the PCL AA affiliate so keeping SA in the SW league was a logical shortcut.)
