After a pair of really close, hard fought games Siemens 1 emerged as the winner of the 2026 South Series and are the Metro South Division Champs! It was the first all-Siemens final since 2013 and both teams played great games. Congratulations to both teams for very strong seasons, and for playing at a high level throughout the playoffs.

Siemens 1 will move on to the State Playoffs against the other Mass Biotech League division winners. You can track their progress on the League Playoffs tab of the main website. Wish them luck as they try their luck against the rest of the league!

* As of 9/01/26.

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: https://www.usasoftball.com/certified-equipment/.

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. You can also use the drop-down menu to filter the list by brand. There is also a section of Non-Approved Bats that contains the 3 lists of banned bats. Keep in mind that an approved single walled aluminum bat can have a composite handle and an aluminum barrel. Always go by the “SW” rating on the USA approved list.

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