AAA Bases are Larger and Closer in 2021

AAA Bases are Larger and Closer in 2021

In an effort to reduce injuries and add offense to the game, MLB has changed the bases in the minor leagues at AAA level. The new bases are flatter (by 1 1/2 inches) and larger (by 3 inches) than the existing bases.

 

Larger, flatter bases in AAA for 2021 are designed to reduce injuries

The baseline from home to 1B is measured from the back tip of home plate to the back of 1B, which is 90ft. This distance remains the same but with larger bases in play, the distance from home to 1B is reduced by three inches. Also, the distance between the bases (1B to 2B, and 2B to 3B) is reduced by 4 1/2 inches.
