Baseball Rule 1.10

A moratorium is in effect on baseball bats that include composite material in the barrel. Some specific models of bats have received waivers of the moratorium. For information on the moratorium, go to http://www.littleleague.org/media/newsarchive/2011/Jan-Apr/LLBBBatInfo-3-18-11.htm

A bat is NOT required to have the “Little League” logo or name to be acceptable. Also, it is NOT required to be on the list of licensed bats here: http://www.littleleague.org/Assets/forms_pubs/2011ApprovedNonWoodBatList.pdf. Instead, this list is a guide, published every year by Little League for many decades, to licensed bats for those considering their purchase.

Any bat simply must: A – Meet the specifications of this rule, and, B – Not be currently subject to the moratorium referenced in the first paragraph above.

Below is the text of Baseball Rule 1.10. It provides the specifications for bats in each of the various divisions of baseball.

Rule 1.10

The bat must be a baseball bat which meets Little League specifications and standards as noted in this rule. It shall be a smooth, rounded stick and made of wood or of material and color tested and proved acceptable to Little League standards.

Little League (Majors) and below: it shall not be more than thirty-three (33) inches in length nor more than two and one-quarter (2¼) inches in diameter. Non-wood bats shall be printed with a BPF (bat performance factor) of 1.15 or less;

Junior League: it shall not be more than 34 inches in length; nor more than 2 5/8 inches in diameter, and if wood, not less than fifteen-sixteenths (15/16) inches in diameter (7/8 inch for bats less than 30”) at its smallest part.

Senior/Big League: it shall not be more than 36 inches in length, nor more than 2 5/8 inches in diameter, and if wood, not less than fifteen-sixteenths (15/16) inches in diameter (7/8 inch for bats less than 30”) at its smallest part. The bat shall not weigh, numerically, more than three ounces less than the length of the bat (e.g., a 33-inch-Iong bat cannot weigh less than 30 ounces). All non-wood bats shall meet the BESR performance standard, and such bats shall be labeled with a permanent certification mark.

In all divisions, wood bats may be taped or fitted with a sleeve for a distance not exceeding sixteen (16) inches (18 inches for Junior/Senior/Big League baseball) from the small end. A non-wood bat must have a grip of cork, tape or composition material, and must extend a minimum of 10 inches from the small end. Slippery tape or similar material is prohibited. An illegal bat must be removed. Any bat that has been altered shall be removed from play.

EXCEPTION: For the 2010-2011 Junior, Senior and Big League regular and tournament season, composite bats are prohibited unless an approved waiver has been granted by Little League International. This wavier will be based on additional testing verifying that the composite bat(s) meet current standards. A list of any approved composite bats can be found on the Little League website at www.littleleague.org. Beginning January 1, 2012, all bats not made of a single piece of wood shall meet the Batted Ball Coefficient of Restitution (BBCOR) performance standard, and such bats shall be labeled with a silkscreen or other permanent certification mark. The certification mark shall be rectangular, a minimum of a half-inch on each side and located on the barrel of the bat in any contrasting color. Aluminum and composite bats shall be labeled as approved tamper evident, and be marked as to their material makeup being aluminum or composite. This marking shall be silkscreen or other permanent certification mark, a minimum of one-half-inch on each side and located on the barrel of the bat in any contrasting color.

NOTE 1: Junior/Senior/Big League: The 2¾ inch in diameter bat is not allowed in any division.
NOTE 2: The traditional batting donut is not permissible
NOTE 3: The bat may carry the mark “Little League Tee Ball.”
NOTE 4: Non-wood bats may develop dents from time to time. Bats that can¬not pass through the approved Little League bat ring for the appropriate division must be removed from play. The 2¼ inch bat ring must be used for bats in the Tee Ball, Minor League and Little League Baseball divisions. The 2 5/8 inch bat ring must be used for bats in the Junior, Senior and Big League divisions of baseball.
