EFFECTIVE NOW: all composite bats are banned.

Due to safety and potential injury issues Double walled, Triple walled and Composite bats have been banned from the league (even if these bats are listed as approved on the USA Softball bat list). Only USA Softball approved Single walled aluminum bats are allowed. Approved Single walled aluminum bats may have a non-aluminum handle - it is the barrel that must be aluminum.

EACH TEAM is responsible for ensuring the bats they use are allowed - if a team needs help, they can reach out to the division coordinator.

For a bat to be allowed for use it must meet the following criteria:

  • It must be USA Softball stamped (formerly ASA). It can have other stamps, but the USA Softball/ASA stamp must be one of them.
  • It must be single walled aluminum. Double-walled, Triple-walled and Composite bats are not allowed. Baseball bats are also not allowed.
  • It must not be on the banned bats list.

To find out whether a bat is USA Softball approved or banned, go to this site:

From there, choose Bats from the drop down menu and click Go. On the next page there is a section for Approved Bats where you can see all of the USA Softball approved bats. There is also a section of Non-Approved Bats that contains the 3 lists of banned bats.

For further info and guidance on bats, please refer to the league rules linked above.

Below is Metro South master bat list. If a question of a bat's legality arises on the field, please consult this list to help clarify the situation. If a bat is not on this list, it should not be used in a game.
