Abstract: The purpose of this study was to identify and describe the batting mechanics of a successful baseball power hitter. The subject used in the analysis was a major league player with all-star credentials. Two Bell and Howell 70DR cameras, supplied with Kodak Ektachrome film, were used to film the subject striking at ten half-speed pitches thrown by a pitcher from the pitcher's mound. Eight of the ten pitches were hit successfully by the subject. The hitting stroke that resulted in the ball being hit with the greatest power was selected by the author for analysis. The film was viewed through a DuKane Cassette Filmstrip Viewer. The acceleration, velocity, and sequential order of movement of selected body segments were analyzed at specific points during the swing. There were still positive accelerations of the bat, hands, hips, and shoulders at the moment of contact with the ball. Considerable shoulder and hip rotation took place throughout the swing. Hip rotation was restricted somewhat due to the closed stance used by the batter. Contrary to the opinion of some authorities, the closed stance and restricted hip rotation did not seem to adversely affect the generation of power by the hitter.
