Louisville Slugger Pro Stock Wood Ash Bat. Ash is Strong timber, lighter weight. Pound for pound, ash is the strongest timber available. Ash has flexibility that isn’t found in other timbers, including maple. It tends to flex rather than break. This gives you a larger, more flexible sweet spot in terms of breakage. Due to ash being a lighter gross weight, we can produce a wider range of larger barrel models. Number 1 Grade Ash. Walker Finish. I13 Turning Model and Cupped End.
