Little League Rules on Compliant Baseball Bats for 2011

I have just received another email from Little League International dated 12/30/10 which now imposes an immediate moratorium on the use of composite non-wood bats at ALL levels of play in Little League Youth Baseball for the upcoming 2011 season. This is a significant expansion of the moratorium originally announced on 9/1/10 which applied to Junior, Senior and Big League Divisions only.

Once again, this email is authorized by Little League International for redistribution so I have reproduced it here in its entirety (with emphases added) for interested readers. The original can also be found at the Little League Online website via the following link:

The bottom line is to avoid the purchase of new composite non-wood bats as described in the following letter if your player will participate in ANY Division of Little League Baseball for 2011!

Little League International has placed a moratorium on the use of composite bats in the Little League (Majors) Division and all other baseball divisions of Little League, effective immediately.

“Today’s decision of the Little League International Board of Directors Executive Committee is based on scientific research data from the University of Massachusetts (Lowell), which was contracted by Little League Baseball,” Stephen D. Keener, President and Chief Executive Officer of Little League Baseball and Softball, said. “The maximum performance standard for non-wood bats in the divisions for 12-year-olds and below is a Bat Performance Factor (BPF) of 1.15. The research found that composite bats, while they may meet the standard when new, can exceed that standard after a break-in process.”

Local Little Leagues were first informed of the research last September.

“From the beginning, and throughout this process, we wanted to keep everyone informed,” Patrick W. Wilson, Vice President of Operations at Little League International, said. “Our intent was to provide local league constituents clear direction regarding composite bats. There is a process through which manufacturers can submit individual models for a possible waiver if they wish to seek it. Going forward, we will let our leagues know which ones meet the standards for the Little League Baseball (Majors) 12-and-under divisions, if any.”

On Sept. 1, Little League International placed a moratorium on composite bats in the Junior, Senior, and Big League Baseball Divisions of Little League. Subsequent to that moratorium, some composite bat models have received a waiver and may be used in those divisions. Information on the composite bats that have received waivers for the Junior, Senior, and Big League Baseball Divisions of Little League may be found here:

At present, no composite bats for the Little League (Majors) Division and below have received a waiver. If and when any models do receive a waiver, Little League International will inform its leagues of that decision. An updated listing of licensed baseball bats approved for use in the Little League (Majors) Division and below can be found here: 2011 Approved Non-Wood Bat List (PDF) (This list was updated on Jan. 7, 2011.)

The moratorium on composite bats, which now applies to all baseball divisions of Little League, does not apply to any softball divisions of Little League.


Note: The moratorium on composite bats only applies to composite-barreled bats. Bats that have only a metal/alloy in the barrel (and no other material, unless it is in the end cap of the bat) are not subject to the moratorium, regardless of the composition of the handle.

EDITOR’S NOTE: This 2011 moratorium on bats for use in Little League Baseball is separate from the new 2010 NCAA/NFHS bat regulations previously identified in other recent posts on DirtDog Baseball. The bat performance research was done at the same facilities for both sets of regulations.
