This study examined offensive production statistics for NCAA Division I baseball for the eight years pre and eight years post NCAA rule change that regulated the size, weight and exit ball batted velocity of collegiate baseball bats. Our study empirically examined five offensive baseball statistical categories in order to determine if the rule change by the NCAA mandating a change in bats accomplished the goal of reducing college baseball’s offensive output. A direct comparison of the -5 and -3 bat was made for 275 Division I Collegiate Baseball Programs from 1991-2006. All teams used an unregulated -5 collegiate bat from 1991-1998 and a regulated -3 bat from 1999-2006. The results yielded trend lines for each of the statistical categories for the eight years pre and eight years post rule change for the intercollegiate baseball bat. We concluded the NCAA rule change helped to accomplish its intention: to reduce offensive production.
