BESR Ball Exit Speed Ratio is a rule which applies to all non-wood bats used by all high schools who are members of the National Federation High School Associations (NFHS).

All non-wood bats used must bear the BESR certification mark.

The Ball Exit Speed Ratio (BESR) mark ensures a maximum exit speed of 97 miles per hour. The rules also a part of the BESR standard, have the following requirement a maximum of 2 5/8 inches diameter bat barrel and a minus-3 differrential between the length and weight. (i.e.,a 33-inch-long bat cannot weigh less than 30 ounces).

Folks all of the above criteria and certification is dedicated to safety for our high school baseball players.

Maybe the rules committee failed to certify or place a mark for size of the boy or muscle strength allowed to use a bat.

Collegiate use of non-wood bats might want to consider this Exit Speed Ratio thing to consider the safety net. A bat with a Ball Exit Speed Ratio maximum above 97 miles per hour might ruin the College homerun records and statistics.

Since professional or major league baseball has placed non-wood bats off limits this BESR thing is of no consequence in professional baseball as of today.

Major league teams still have to contend with the "Tar Baby Bat" because George just might knock the tar out of that hosshide.
