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 USABat standard does 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. Metal and composite bats also tend to be more durable and lighter weight than wood bats. USA Baseball Approved Bats (USABats) are designed to perform much like wood, where their performance is 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. That said, the two standards establish similar performance limits for bats.
The performance of BBCOR and USA Baseball bats are nearly identical (within about 0.005 BBCOR). The primary difference between the bats is USA Baseball bats do not have the -3 drop weight restriction. The lighter USA Baseball bats are easier to swing (particularly for developing hitters); this can result in higher batting averages, but not higher hit ball speed. The lighter USA Baseball bats will produce slightly lower hit ball speeds than the BBCOR bats. Since USA Baseball bats can be produced in a -3 drop weight, and would be nearly identical to BBCOR bats, we see no reason why BBCOR and USA Baseball’s bats could not be combined in play for leagues choosing this option. However, we note that mixing BBCOR and USA Baseball bats increases the range of player ability using these bats. Rules ensuring players of comparable ability are on the field will lower the likelihood of an advanced hitter putting an inexperienced pitcher at risk. — Dr. Lloyd Smith and Dr. Alan Nathan
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 University
- Glenn Fleisig, Ph.D. Research Director of American Sports Medicine Institute
Is safety the reason for the change?
No. Youth baseball continues to be one of the safest of all sports for youth participants. USA Baseball and its National Member Organizations believe a wood like performance standard for non-wood bats will benefit the long term integrity of youth baseball.
How will I know which bat to buy?
All bats that bear the USA Baseball mark are permissible for play in leagues and tournaments that require USABat. A full list of certified bats can be found here.
Are wood bats still allowed?
Yes. Solid, one piece wood bats are approved for use under USABat with or without the USA Baseball Certification Mark. Multi-piece and composite wood bats must feature the USA Baseball Certification Mark to be approved for play.
Does USABat have a drop-weight limit?
There is no drop-weight limit under USABat. All certified bats that feature the USA Baseball mark and appear on the approved bat list are approved for play in leagues that require USABat regardless of weight or drop weight. Any bats listed as tee ball bats are only approved use with approved tee balls.
Does USABat have a barrel diameter limit?
USA Baseball approved bats (USABats) are certified with barrel diameters of 2-5/8″ and less. Approved bats feature a variety of barrel diameters including 2-5/8″, 2-1/2″, 2-3/8″, 2-1/4″ and 2″. As long as a bat features the USA Baseball mark and appears on the approved bat list, it is approved for play regardless of barrel diameter.
How are USABats certified?
Bats must undergo performance testing and receive a final approval from USA Baseball to receive USABat certification. A bat maker’s first step in this process is to produce a bat design sample and submit it to the Washington State University (WSU) Sports Science Lab for performance testing. Submissions that pass USA Baseball’s Performance Test Protocol become eligible for certification. To clarify, this means the bat has been performance tested in a controlled lab setting to confirm that it performs at a wood-like standard. The bat maker must then send a sample of the same design to USA Baseball for final approval of graphics. USA Baseball’s certification gives the bat maker rights to manufacture the same design for retail sale that passed testing at WSU with the graphics that were approved by USA Baseball as well as add the USA Baseball mark on the bat’s handle. All approved bats are added to the USABat Approved List at USABat.com.
How does a bat decertification happen?
In order for USA Baseball to ensure the integrity of the USABat standard, USA Baseball reserves the right to compliance test any bat on the USABat approved bat list at any time. Compliance tests are undertaken to ensure that production bats sold at retail meet the USABat standard and are identical to the bats submitted by the manufacturers during the initial certification process. In the event of a compliance test, select bat models are purchased at retail and tested at the Washington State University Sports Science Lab using the original certification test process. If the test reveals the bat model being sold at retail does not comply with USABat performance and design requirements, the bat is deemed noncompliant and the decertification process begins.
What does bat decertification mean?
Bat decertification means that production bats being sold at retail of a previously approved USABat model are not in compliance with the USABat standard. To clarify, the USABat standard requires that bats manufactured for retail sale match the design that was initially certified by USA Baseball in both performance and design. Once a bat model has been decertified, it is no longer approved for play in leagues that have adopted USABat and subject to league rules concerning the use of illegal or unapproved bats.
When is a bat decertification announced?
USA Baseball is obligated to announce a bat decertification once compliance testing has been completed and USA Baseball receives conclusive evidence that a bat model is not compliant with the USABat standard.
Why not wait until the end of the season to announce a bat decertification?
Both USA Baseball and the bat manufacturer are obligated to announce a bat decertification once compliance testing has been completed and after USA Baseball has conclusive evidence that a bat model is out of compliance with the USABat standard. The use of a noncompliant bat in leagues that have adopted USABat compromises the integrity of the standard and creates an uneven playing field across youth baseball. Therefore, in order to maintain integrity with the performance metrics set by the USABat standard, noncompliant bats must be decertified and removed from play immediately .
What happens if my bat is decertified?
If a previously approved USABat is decertified, the bat manufacturer is obligated to provide consumers with relief and to take any other steps necessary to make such parties whole. USA Baseball will post information on how to contact the bat manufacturer at https://usabat.com/decertified-bats/ in the event a USABat is ever decertified.
Why are certain bat lengths decertified and not others?
For certified bats, each model length is typically designed and produced slightly differently than the others. Because of this, individual lengths and drops of a USABat are classified as unique designs and subject to bat certification separately. It is possible that certain bat lengths could be found to be out of compliance under the USABat standard while the remaining lengths and drops of the same model family are still design and performance compliant.
Does the standard impact Tee Ball?
Yes. Under the USABat standard, certified tee ball bats will feature the USA Baseball mark and text which reads ONLY FOR USE WITH APPROVED TEE BALLS.
What bats are recommended for coach pitch and machine pitch leagues?
Both tee ball bats and standard youth bats featuring the USA Baseball certification mark are recommended for coach pitch and machine pitch leagues. Coach pitch and machine pitch leagues that permit the use of USABat tee ball bats should only use approved low compression baseballs. A full list of approved low compression baseballs can be found here: https://usabat.com/approved-tee-balls/
We have compared the performance of tee ball bats using tee balls and youth baseballs. Low compression tee balls reduced bat performance by 0.04 BBCORR (a substantial amount). Further, the dynamic stiffness of tee balls is a factor of 10 lower than youth baseballs. The reduced stiffness will correlate to lower impact force, and the reduced COR correlates to lower hit ball speed. Both factors will significantly reduce the likelihood a player is injured if they are hit by a ball. As hit ball speed depends much more on the bat speed, than the pitch speed, these trends would also hold true for tee balls used in coach pitch games. — Dr. Lloyd Smith and Dr. Alan Nathan
Can I use a Tee Ball bat that does not feature the USA Baseball mark?
All Tee Ball bats must feature the USA Baseball mark and accompanying text. Tee Ball bats that were produced and/or purchased prior to the implementation of the new standard can be certified using an Approved Tee Ball Sticker via the USA Baseball Tee Ball Sticker Program.
What is the USA Baseball Tee Ball Sticker Program?
The USA Baseball Tee Ball Sticker Program is an initiative designed to allow for the continued use of tee ball bats that were manufactured prior to the implementation of the new USABat standard. Through this program, parents, leagues, and coaches can place approved stickers marked with the USA Baseball logo and language which reads: ONLY FOR USE WITH APPROVED TEE BALLS on their older model tee ball bats. Stickered tee ball bats are fully compliant as approved USABat Tee Ball Bats. All new approved tee ball bats feature a permanent USA Baseball logo and do not require an additional sticker.
