13-15 BASEBALL DIVISION
The bat may not exceed 34” in length, and the bat barrel may not
exceed 2 5/8” in diameter. All aluminum/alloy barrel bats
and all composite handle (only) aluminum/alloy barrels are
allowed. Only composite barrel bats certified and marked
will be allowed. Wood barrel bats conforming to the
specifications of Official Baseball Rule 1.10 are allowed.
Implementation of USABat Standard Began on
January 1, 2018
USA Baseball, the national governing body for the sport of
baseball in the U.S., in conjunction with participating national
member organizations (NMOs) announced the decision to adopt a
new method for measuring bat performance in the testing of youth
bats. Informed by the research of leading scientists on the USA
Baseball Bat Study Committee, and supported by its NMOs, --
including the American Amateur Baseball Congress (AABC), Amateur
Athletic Union (AAU), Babe
Ripken Baseball, Dixie Youth Baseball, Little League Baseball
and PONY Baseball -- USA Baseball has concluded that recent
advancements in science, engineering, technology, and the
materials available to fabricate non-wood bats, now allow the
manufacturers to construct youth bats that can perform at a
wood-like level through the entire range of lengths and weights
of youth bats.
The new USA Baseball bat standard (USABat), which will apply to
bats that are classified below the NCAA and NFHS level of play,
was implemented on January 1, 2018.
Similar to the NCAA and NFHS BBCOR standard, which helped to
eliminate discrepancies with different length bats and thus
provide a more direct measure of bat performance, the new USA
Baseball bat standard will allow youth baseball organizations in
the United States to reach their goal of establishing a
wood-like standard, a standard that will provide for the
long-term integrity of the game.

Frequently Asked Questions about the USABat standard:
Which national member organizations are implementing this new
To date, the following organizations are participating (in
alphabetical order): American Amateur Baseball Congress
(AABC), Amateur Athletic Union (AAU), Babe Ruth Baseball/Cal
Ripken Baseball, Dixie Youth Baseball, Little League
Baseball and PONY Baseball.
Why the change to a wood-like standard?
USA Baseball’s national member organizations believe that a
wood-like performance standard will best provide for the
long-term integrity of the game. The new standard will not
have a drop-weight limit, so young players can use bats made
with light-weight materials.
Why not just use wood bats?
Wood is a scarce resource. The new bats will be designed to
perform much like wood, where its performance will be
limited to the highest performing wood.
How is the USABat standard different from the BBCOR standard
used by the NCAA and NFHS?
Both the USA Baseball and NCAA bat performance tests are
based on the coefficient of restitution from a bat-ball
impact. The scale of results is different, however, since
they use different test balls and test speeds. The testing
difference is necessary to address the various levels of
play in the respective age groups.
Why is USA Baseball involved?
The national member organizations asked USA Baseball as the
national governing body to take the lead in this process to
establish a new standard. Many other national governing
bodies set and enforce standards for the equipment in their
respective sports. To that end, USA Baseball established a
Bat Study Committee of leading scientists and conducted
theoretical modeling, field testing and lab testing. The
committee shared its findings with the national member
organizations, who then endorsed the new USABat standard.
Who were the scientists on the USA Baseball Bat Study Committee?
Alan Nathan, Ph.D., Professor Emeritus of Physics at the
University of Illinois
Dan Russell, Ph.D. Professor of Acoustics at Penn State
Glenn Fleisig, Ph.D. Research Director of American Sports
Is safety the reason for the change?
No. Youth baseball continues to be one of the safest of all
sports for youth participants.
How will I know which bat to buy?
All new bats that bear the USABat licensing mark will be
permissible for play in the leagues and tournaments of the
participating youth baseball organizations.
