  • End configuration for a baseball bat
    Patent number: 7137913
    Abstract: An end configuration for a bat includes in one embodiment an end cap that has a base that is shaped to fit within the open end of the bat thereby to attach the end cap to the bat. The end cap also includes a convexly contoured end surface that is exposed when the end cap is attached to the bat. The end surface is roughened to reduce the aerodynamic drag when the bat is swung, thereby to increase the momentum of the bat for a given amount of force applied to swing the bat.
