In 2002, Jack Marucci, LSU Tigers head athletic trainer at that time, built his first baseball bat in his backyard shed after he was unable to find a suitable wooden bat for his son Gino.

Word of mouth traveled fast about his custom built wooden bats,and shortly thereafter he was making prototypes in his backyard shed for MLB players.
