Crafted for excellence. Designed with new, thermally treated AZR alloy for a more responsive, forgiving feel, the CAT9 aluminum bat features a massive sweet spot that is ready to do damage right out of the wrapper. Utilizing a three-stage thermal treatment process, Marucci's new AZR alloy offers a more responsive microstructure for a better feel, more forgiveness, and more performance while maintaining the same strength as its predecessor.
