KVBSA — Kensington Valley Baseball & Softball Association

Large Metro Detroit / SE Michigan community travel association (roughly 8U–18U) with many participating towns. Website: kvbsa.com.

8U–14UUSSSA family

USA batsAllowed (more restrictive)

15U–18UBBCOR / wood (NFHS)

13UOften −8 max drop

Published bat pattern (KVBSA Bat Guidelines)

For 8U–14U, KVBSA follows USSSA standards: non-wood bats need the USSSA 1.15 BPF stamp; BBCOR and one-piece wood are also legal. USABat bats are allowed because they meet the more restrictive USA standard (you may give up performance vs big-barrel USSSA).

For 15U–18U, KVBSA follows NFHS: non-wood must be BBCOR .50 (typically −3) or wood.

Parent checklist

Travel weekends may use a different sanction (PG / USSSA event tab) — check that weekend’s sheet.
USA-only house programs in the same town are not the same as KVBSA travel rules.
At 15U+, plan on BBCOR −3 even if younger siblings still swing USSSA.

Confirm with KVBSA: Participating communities share the association rules, but each town may add notes. Read the current Rules PDF.
