Yes. Solid, one piece wood bats are approved for use under USABat with or without the USA Baseball Certification Mark. Multi-piece and composite wood bats must feature the USA Baseball Certification Mark to be approved for play. Bats made of multiple pieces of wood, sawdust, or including man-made materials, are considered composite wood bats.

Players need a glove and cleats, and boys should have an athletic cup (for Shetland and above). Cleats should be rubber soled until the Bronco division, at which time metal cleats are permitted (but never on portable mounds). Each Manger will have an equipment bag with one or two batting helmets (at youngest levels), a complete set of catcher's gear, and a catcher's glove. We recommend each player have their own bat and batting helmet since comfort and familiarity are important factors with this equipment. When considering buying a bat, make sure to review the Pony Bat Rules first. For some helmet buying assistance, check out this Batting Helmet Buying Guide. For baseball bats, here is a good guide from Demarini to help you select the proper size. For baseball gloves, here is some general buying info.
