Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A ball bat barrel has an interior surface and a luminescent layer on the interior surface. The luminescent layer, upon being charged, emits light that indicates tampering with the interior surface.

Abstract: A ball bat extending about a longitudinal axis. The bat includes a barrel portion defining a primary tubular ball impact region. The barrel portion is formed of a fiber composite material. The fiber composite material includes at least first and second plies. The first and second plies include first and second pluralities first and second resins, respectively. Substantially all of the first and second pluralities of fibers of the first and second plies are generally aligned to define first and second angles with respect to the axis, respectively. The angles are each within the range of 45 to 90 degrees. Each of the plies is sized to extend about the full circumference of the barrel portion. The first and second pluralities of fibers are sectioned such that the fibers do not continuously extend about the full circumference of the impact region.

Abstract: A ball bat extending about a longitudinal axis. The bat includes a barrel portion defining a primary tubular region. The tubular region is formed of a fiber composite material having wall thickness of at least 0.100 inch. The fiber composite material includes at least first and second plies. The first and second plies include first and second pluralities of fibers and first and second resins, respectively. Substantially all of the first and second pluralities of fibers of the first and second plies are aligned to define first and second angles of 45 to 90 degrees with respect to the axis, respectively. The first and second plies have opposite polarities and are positioned with the second ply applied over the first ply. The first and second pluralities of fibers are sectioned such that the fibers do not continuously extend about the full circumference of the tubular region.
