A Minor league is a professional baseball league that is considered less prestigious than a top-level, or "major" league. In the Bull Baseball League, there are five levels of minor leagues below the major-level Bull League.
The teams usually have smaller fan bases (though not necessarily less dedicated ones), play to smaller markets, and smaller budgets. The minor leagues as a whole are sometimes referred to as a farm system, and are said to be part of a franchise or organization within a parent team.
In the Bull Baseball League, all minor league teams must be affiliated with a parent Bull League (major-level) team. As there is no minor league financial system within the OOTP18 game system, the only players who earn a salary from the major-level team are ones who are on the 40-man (secondary) roster but not on the 25-man active roster.
There are five levels of minor leagues within the Bull League. From highest to lowest, they are:
|AAA||Triple-A||Cow League (CL)||1995||Highest minor league level|
|AA||Double-A||Heifer League (HL)||2013||Full season developmental level|
|A||Single-A||Calf League (CaL)||2004||Full season low developmental level|
|S A||Short Season A||Milk League (ML)||2013†|| Initial draftee level, Season starts after amateur draft|
Players must be aged 24 and under to qualify
|Rk||Rookie||Florida Rookie League (FRL)||2017||Players must be age 21 or under to qualify|
† — Initially introduced as a Rookie level league, then reclassified as Short Season A after the FRL was added.
