Just got this the other day:
DATE: January 20, 2011
TO: Athletic Directors and Head Baseball Coaches
FROM: Gene Menees, Assistant Executive Director
SUBJECT: Legal Baseball Bats
As a reminder for the 2011 high school baseball season, legal bats can come from 1 of 3 categories:
1) Bats that have BESR permanently stamped on the barrel
2) Bats that have BBCOR permanently stamped on the barrel
3) Composite bats that are listed on our website
Any bat within 1 of these 3 groups is legal for the 2011 baseball year.
