Minor League Baseball (fictional)

Reorganization of 2021
The following changes have since been implemented:
 * The independent American Association, Atlantic League, Pacific States League, and Frontier League, the formerly collegiate East Coast League and formerly Rookie-level Pioneer League became MLB Partner Leagues, with the ability for MLB clubs to acquire players from the Partner Leagues to assign to affiliated clubs.
 * Four independent league teams—the St. Paul Saints, the Sugar Land Skeeters (renamed the "Sugar Land Space Cowboys" in 2022), Na Koa Ikaika Maui, and the Somerset Patriots—were brought into MiLB. The Skeeters became the Triple-A affiliate of the Houston Astros, the Saints became the Triple-A affiliate of the Minnesota Twins, Na Koa Ikaika became the new Class-A affiliate of the Honolulu Warriors, and the Patriots became the Double-A affiliate of the New York Yankees.
