Louisville Slugger Wood Bat XX Prime Maple Pro S318 Turning Model. 33 Inch Wood Baseball Bat. Maple is the species preferred by most pro players. It features the ultimate surface hardness and provides an unmatched sound and feel at contact. Naturally harder, maple offers added strength at impact. Closed grains eliminate flaking, commonly seen with ash, allowing superior durability against delamination. The balanced swing weight of the C271 – among the top three turning models ordered by the pros – maximizes bat control and a player’s ability to get the barrel where it needs to be, when it needs to be there.
