What type of bat is considered legal if it meets all other bat requirements, despite having manufactured holes in the taper?

A bat that has manufactured holes or ridges is considered legal as long as it meets all other bat requirements set by NFHS regulations. This is because the specific use of holes does not inherently affect the bat's performance or integrity if the overall structure complies with the rules. The focus in these regulations is on factors such as weight, length, material composition, and performance standards, not solely on surface texture or the presence of holes.

It's important to note that while a bat with a smooth barrel or one made entirely of wood could also be legal, the question specifically highlights the unique case of a bat with manufactured holes. Furthermore, a bat with a BBCOR certification mark indicates that it meets particular performance standards, but that does not specifically address the aspect of manufactured holes present in the taper. Hence, the answer highlighting manufactured holes acknowledges flexibility in design while adhering to compliance standards.
