OBA Bat Rule

BAT RULES (P2-5)

Baseball Ontario enforces the following rules in regards to bats:

In Minor Midget, Midget, Junior, and Senior, only wood bats may be used. These are subject to provisions in the Official Rules of Baseball.

In Major Bantam, metal bats may be used. They may not exceed 2 3/4" diameter, and the weight: length differential may not exceed 5 oz. For example, the minimum weight of a 34" bat is 29 ounces.

ENFORCEMENT:

A player using a bat that violates this rule shall be declared out AND ejected under Rule 6.06(d). All runners return to the base occupied at the time of the pitch.

All bats must clearly show the manufacturers' original marking of length-weight differential. If not, the bat will be considered illegal.

Any bat declared illegal under this rule shall be removed from the game and will be returned to the offending team after the tournament.

Umpires are to discuss this issue at ground rules and check and remove any illegal bats before the game.

In Bantam Girls, Minor Bantam, Peewee, Mosquito and Rookie Ball, metal bats are permitted with no restrictions beyond the provisions of the Official Rules of Baseball.

NOTES:

For the purposes of the rule outlined above, the following are to be considered wood bats:

Bamboo bats
Composite wood bats
All BESR certified bats are allowed in Baseball Ontario play, with the understanding the list may be modified from time to time. Solid wood bats are always approved for Baseball Ontario play.
