## Abstract

A corked bat is believed by many to give a batter an advantage over the pitcher while at bat. This theory was tested by measuring the distance that two identical bats hit the balls before and after being drilled and corked. A skeet shooter was modified to fit this need. Three identical baseball bats of same length that were made by the same company took twenty-five swings on a modified skeet shooter. When this process occurred, the bat speeds were constant as the speed of the bat was 65 mph. Each distance the ball traveled away from the tee was recorded in meters. A hole three-fourths of an inch in diameter and five inches deep was drilled through the center of the bats. Three wine corks were then pressed down into the hole. Each bat then took twenty-five swings with the distances having been recorded in meters. The data then showed that the cork did affect the ball by allowing the ball to travel 5.6% shorter than the wooden bat.

A corked bat is believed by many to give a batter an advantage over the pitcher while at bat. This theory was tested by measuring the distance that two identical bats hit the balls before and after being drilled and corked. A skeet shooter was modified to fit this need. Three identical baseball bats of same length that were made by the same company took twenty-five swings on a modified skeet shooter. When this process occurred, the bat speeds were constant as the speed of the bat was 65 mph. Each distance the ball traveled away from the tee was recorded in meters. A hole three-fourths of an inch in diameter and five inches deep was drilled through the center of the bats. Three wine corks were then pressed down into the hole. Each bat then took twenty-five swings with the distances having been recorded in meters. The data then showed that the cork did affect the ball by allowing the ball to travel 5.6% shorter than the wooden bat.
