Little League baseball has banned (or suspended) composite bat use in their Junior League (13-14), Senior League (15-16) and Big League (17-18) divisions. It does NOT apply to their Major League (9-12) division which is where most kids play. Their statement, released on September 1, 2010 is listed below:
A moratorium on the use of composite bats in the Junior, Senior, and Big League Baseball Divisions of Little League was enacted on Aug. 27, 2010, by the Little League International Board of Directors, effective immediately. The moratorium shall be in effect until further notice by Little League International.
The moratorium covers all games and practices only in the three divisions referenced above. It closely follows a similar moratorium approved in July 2010 by the National Federation of High School Associations (NFHS), based on a recommendation from its Baseball Rules Committee. The NFHS Board enacted a rule to prohibit the use of composite bats until they can produce consistent compliance with the standards through the life of the bat.
Waivers of the moratorium may be considered by Little League International in certain circumstances. For 2011, a manufacturer may apply for a waiver of the moratorium for a particular model of composite bat if all of the requirements for a waiver, as established by Little League International, are satisfied. Composite bats that are certified by an approved independent testing laboratory as meeting the current Ball Exit Speed Ratio (BESR), and the Accelerated Break-In (ABI) procedure, will be eligible for the waiver in 2011. Little League International will provide a list of bat models, if any, that receive waivers of the moratorium.
Not covered under the Little League moratorium are wood bats, metal bats, or bats that have composite materials in the handle only. A composite bat is one that has a metal shell, but a woven composite of fibers on the inside of the barrel portion of the bat.
“Currently, the moratorium on composite bats does not apply to the Little League Baseball (Majors) Division and below, nor does it apply to any division of softball,” Patrick W. Wilson, Vice President of Operations at Little League International, said. “Little League International, in consultation with independent experts, anticipates being able to provide local league constituents clear direction regarding composite bats in the Little League Baseball (Majors) 12-and-under divisions, prior to the start of the 2011 season.”
