The “guidance” from the National Federation of High Schools is very confusing.
NFHS release dated July 7, 2010 – changes to take effect during the 2010-2011 year forbid the use of composite bats until they can meet the Batted Ball Coefficient of Restitution (BBCOR) performance standard.
NFHS release dated July 20, 2010 – states that waivers may be considered for certain types or models of composite bats that can produce consistent results through the life of the bat and remain within the applicable test standard. States NFHS may work with manufacturers on waivers.
NFHS release dated July 28, 2010 – (note – this release postdates the July 7 release) related to baseball rule changes. States:
“ Through December 31, 2011, each aluminum bat shall meet the Ball Exit-Speed Ratio (BESR) performance standard, and such bats shall be labeled with a silkscreen or other permanent certification mark. No BESR label, sticker or decal will be accepted on any non-wood bat.
e. Beginning January 1, 2012, all bats not made of a single piece of wood shall meet the Batted Ball Coefficient of Restitution (BBCOR) performance standard, and such bats shall be labeled with a silkscreen or other permanent certification mark.”
This most recent release does not appear to move up the effective date of the BBCOR rules.
NFHS release dated August 5, 2010 – provides a list (and pictures) of approved BESR-ABI Composite Baseball Bats. All appear to be Demarini and Vendetta bats.
