how many divisions are there in minor league baseball
Minor League Baseball The current minor league classification system divides leagues into one of five classes, those being Triple-A (AAA), Double-A (AA), Class A (Single-A or A), Class A Short Season, and Rookie. Furthermore, Class A is further subdivided into Class A and Class A-Advanced (often called Low-A and High-A, respectively), and Rookie is further subdivided into Rookie Advanced, Complex-based Rookie and international summer baseball. Under the rules governing the affiliated minor leagues (specifically Major League Baseball Rule 51), Class A Short Season is a separate classification from the other leagues bearing the "Class A" name, despite the similarity in name.
Major League Baseball rosters A Major League Baseball roster is a roster of players allowed by league agreement to play for their respective Major League Baseball team. There are two types of rosters in general, the "active roster" of 25 players and the "expanded roster" of 40 players.
