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.  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

Why wait until 2018?

The implementation date of 2018 will allow bat manufacturers sufficient time to conduct the appropriate research, design, testing, manufacturing and shipping needed to get new bats into retail outlets. This date also allows the participating national member organizations adequate time to educate their memberships of the USABat standard.

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 new bats that bear the USABat licensing mark will be permissible for play in the leagues and tournaments of the participating youth baseball organizations. 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 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:

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 purchase approved stickers marked with the USA Baseball logo and language which reads: ONLY FOR USE WITH APPROVED TEE BALLS.

Tee Ball Stickers can be ordered via

Tee ball stickers will be available for purchase while supplies last.  Regardless of supplies, no sales will happen after May 31, 2018.
