A ball bat includes a barrel portion, a handle portion, and a joint connecting the handle portion to the barrel portion. In some embodiments, the joint includes a releasable connector configured to releasably connect the barrel portion to the handle portion. In some embodiments, the joint includes two releasable connectors to releasably connect the barrel portion to the handle portion. The ball bat may include a flexible rod element positioned between the two releasable connectors. The rod element may include an elastomeric material. In some embodiments, the ball bat may further include a safety connector between the barrel portion and the handle portion or a releasable connector may include a threaded connection to resist release of the releasable connector. In some embodiments, the joint may include a rotatable element for adjusting flex.

A bat customization method includes the steps of capturing images of a batter's swing, determining a swing plane angle of the batter's swing at ball impact at a middle elevation of a strike zone of the batter based upon the captured images, and providing a bat for the batter. The bat has circumferentially spaced launch angle boosters. Each of the launch angle boosters extends along the axis at an angle based upon the determined swing plane angle.

A ball bat including one of a left-hand configuration designated for a left-handed batter and a right hand configuration designated for a right-handed batter. The left hand configuration is different than the right hand configuration. The ball bat further includes one of a left-hand indicia indicating the left hand configuration and a right hand indicia indicating the right hand configuration.

A baseball bat having a body with spaced ends, a barrel region at one end and a handle region at the other end. A safety assembly has an elongate member that extends through at least a part of the body and is connected at spaced first and second locations to the body. The elongate member is operable to at least momentarily exert a restraining force on a fragmented part of the barrel region to thereby avoid unimpeded movement of the fragmented part of the barrel region away from the handle region.

A ball bat for impacting a ball and extending along a longitudinal axis may include a handle portion and a barrel portion coupled to the handle portion. The barrel portion may include circumferentially spaced launch angle boosters. Each of the launch angle boosters extend along the axis at an angle of at least 3 and no greater than 12 from the longitudinal axis.
