Approved bats shall be a softball bat, not be more than 33 inches in length nor more than 2 1/4" in diameter. Non-wood bats must be labeled with a BPF (bat performance factor) of 1.20 or less. Composite softball bats are acceptable as long as they meet these specifications.
All bats in these divisions must be checked and bear the league-approved softball bat sticker to show they are approved for play. Only members of the League's Board of Directors can approve and sticker bats. Talk to your team's manager to determine how to get your bat approved. Penalties for the use of unapproved or unstickered bats are outlined in each division's rules. Tee ball bats are not approved for use in any non-tee ball division.
