On November 26, 2022 the Baseball Alberta Board voted to align with the WCBA 15U bat regulation. In 2023, players in 15UA and 15UAA will now be able to use a drop five (-5) aluminum or aluminum composite bat that is up to 2-¾” in diameter, during league play and Provincial Championships. This rule was adopted to better allow players to transition from drop ten (-10) bats in 13U to what was, drop three (-3) bats in 15U prior to the 2023 season. This rule change is not mandated and players are still permitted to use drop three (-3) bats measuring 2-?” in diameter. 15UAAA remains wood or wood composite only.
