One of six new rules changes by the National Federation of State High School Associations (NFHS) Baseball Rules Committee forbids the use of composite bats until they can meet the Batted Ball Coefficient of Restitution (BBCOR) performance standard. The changes, which were subsequently approved by the NFHS Board of Directors, will take effect with the 2010-11 school year.

After thorough testing by the Baseball Research Center at the U. of Massachusetts??¢????????Lowell, the NFHS Baseball Rules Committee voted to outlaw composite bats until they can produce consistent results through the life of the bat, be made tamper-evident and be labeled as a composite product.
