The invention provides for baseball bat velocity sensing apparatus and method, which employs at least one sensor that may be selectively attached to a batting glove. To facilitate use of the system and avoid interference with the batters swing, swinging or hitting characteristics of the bat, the apparatus of the present invention is selectively positioned in association with the batter's hands during his/her swing. The apparatus provides an output that is responsive to swing movement, and measures the velocity of the swing and bat speed for display to a user. The method and apparatus of the present invention may be employed with any type of bat and regular bats may be used without any required modification or attachments. Thus, for example, bat velocity may be determined in the ordinary course of a baseball game. The invention is easily and conveniently used without materially altering or interfering with the batter's ordinary swings. Accordingly, the bat speed measuring apparatus of the present invention embodied as a separate, small, lightweight, self-contained device. Such a device is selectively secured in association with a batter's hands, such as by selective securance with a standard batting glove.
