Attn. West Seattle Baseball Families:
Before you buy that expensive bat for the coming season, please note the following bat rule changes to enhance safety of defensive players:
-
2-3/4 inch barrel bats are prohibited.
-
2-5/8 inch barrel bats are allowed. Bats with a drop of minus three (-3), must be BBCOR certified
-
2-1/4 inch barrel bats are allowed but must have a Bat Performance Factor of 1.15 or less. In addition, all newly manufactured bats must be stamped “approved for play in PONY Baseball”.
In summary, Bronco and Pony players are have two choices: 2-1/4 inch bats or 2-5/8 inch bats. Most players will choose the 2-5/8 inch diameter bat due to the larger sweet spot.
BBCOR certification requirement will not likely come into play for our Bronco and Pony players since it only applies to minus 3 (weight minus length) bats. A minus 3 bat is a heavier bat used by older, stronger players in high school and college. BBCOR stands for batted ball coefficient of restitution. A BBCOR certified bat has a batted ball coefficient of restitution of 0.5 which limits the trampoline effect off the bat. In addition, a BBCOR certified bat has a minimum moment of inertia which is an attempt to limit the swing speed. Since most of our players will prefer larger bat drops (i.e., -6,-7, etc.), this restriction should not come into play.
Below is a general bat selection guide that may be useful in finding the suggested length for a player depending on the player’s weight and height.
Simple physics says a heavier bat will send the ball further. However, a heavier bat is harder to swing. If a player cannot hold the bat for 20 seconds without the arm starting to shake, it’s too heavy.
If you have any questions on the new bat rules, please ask your player’s coach or any Pony Board Member. Thanks.
