Grip
The grip is simply the covering that bat manufacturers use on the handle
of aluminum bats
Rubber grips absorb more of the shock
Leather or synthetic leather gives a tackier feel for a surer grip
Some bats come with a cushioned grip to decrease the shock even more
5) Bat Performance Factor (BPF) and League Regulations
An effort by some of governing bodies in Baseball and Softball (NCAA, NHSF,
USSSA, NSA) to regulate the performance of a bat has lead to the establishment
of a method of measuring how a ball jumps off of a bat compared to how a ball
rebounds off of a wall at a controlled speed.
BPF (Bat Performance Factor) is simply the increase in the liveliness of a ball
hitting a bat compared to throwing a ball against a solid wall (i.e., 20% faster
rebound = a BPF of 1.20).
Beginning with the 2009 season, non-wood bats used in divisions of play Little
League (Majors) and below must be printed with a BPF (bat performance factor)
rating of 1.15 or less.
Beginning with the 1998 playing season, USSSA and NSA league play must use a
bat bearing a permanent marking indicating that the bat does not exceed a 1.20
BPF rating.
The NCAA/NFHS have dictated a "3 Prong" set of rules for bats to be legal for
2000 and beyond.
The bats can have a diameter no larger than 2 5/8"(6.38 cm)
The bats can be no lighter than 3 ounces less than the length (i.e. 32
in/29 oz or 81.3 cm / 822 gr)
The bats can have an exit speed no higher than 97 MPH off the barrel of
the bat. The bats must have a "BESR" logo on the barrel of the bat,
designating that the bat meets the Ball Exit Speed Requirement
In July of 2003, the ASA changed their performance test method and standard.
They refer to their new test as a "high speed test." This method determines the
outgoing speed of a ball after an impact at 110 miles per hour. Past tests have
had impact speeds of 60 mph. The new standard calls for an outgoing ball speed
of no greater than 98 mph. All bats need to pass this test to be used in ASA play
from 1/1/2004 and beyond.
Bats manufactured after passing this new test will have a new "ASA 2004"
logo on the barrel.
Those that pass the standard will be placed on the ASA's website on an
ASA 2004 legal bat list.
