The new “USA Baseball” stamped bats are detuned compared to existing bats (meaning balls leave the USA Baseball bat at a lower velocity.) The new bat barrels are 2-5/8 inches (big barrel) as opposed to the current 2-1/4 inch. This extra barrel size should be better for contact especially with the younger players. More contact means more balls in play. For our travel program players, we anticipate that each league we participate in (USABL, NPGL, SPFBL, etc.) will adopt the same bat regulations as Babe Ruth and Ripken. Some non-Ripken or Babe Ruth tournaments may allow the old bats or a non- stamped bat and in such cases it is best to check with the tournament organizers.
