In baseball, a corked bat is a specially modified baseball bat that has been filled with cork or other less dense substances to make the bat lighter. A lighter bat gives a hitter a quicker swing and may improve the hitter's timing. Despite popular belief that corking a bat creates a "trampoline effect" which causes a batted ball to travel farther, In Major League Baseball, modifying a bat with foreign substances and using it in play is illegal and subject to ejection and further punishment.
Construction
To cork a bat, a hole approximately in diameter is drilled down through the thick end of the bat roughly deep. Crushed cork, bouncy balls, sawdust, or other similar material is compacted into the hole and the end is typically patched up with glue and sawdust. However, this weakens the bat's structural integrity and makes it more susceptible to breakage, even more so if the cork is placed beyond six inches into the bat. Corked bats are sometimes discovered when they break during the moment of impact upon hitting a baseball.
Major League Baseball
Using a corked bat in Major League Baseball is in violation of Rule 6.03 (a)(5), which states
<blockquote>
A batter is out for illegal action when:
(5) He uses or attempts to use a bat that, in the umpire's judgment, has been altered or tampered with in such a way to improve the distance factor or cause an unusual reaction on the baseball. This includes bats that are filled, flat-surfaced, nailed, hollowed, grooved or covered with a substance such as paraffin, wax, etc. A lighter bat can, however, create an advantage by letting the batter delay a swing for a fraction of a second, which would allow for more accuracy.

Nettles avoided a suspension after explaining that the bat was given to him by a fan. Hatcher had used a teammate's bat after his own shattered, and was backed up on that claim by his manager, Hal Lanier. Sabo also denied knowledge that his bat had been tampered with, moreover the bat audibly cracked on a foul ball before breaking, leading the broadcast crew to question whether Sabo would have knowingly risked continuing to use a cracked illegal bat. On the flip side, Guerrero chased bat pieces after his lumber shattered, a rather unusual reaction, and later admitted to using it intentionally the prior few months. Belle's teammates broke into the umpire's room and swapped the bat with an innocent one, but were caught doing so.
In addition, a number of former players have been accused of and/or admitted to using corked bats. Former Kansas City Royals star Amos Otis is one of them. Another is former player announcer, and National League president Bill White. Former player and Major League manager Phil Garner admitted in January 2010 on a Houston radio station that he used a corked bat against Gaylord Perry and "hit a home run" with it. Garner also admitted that the 2005 Houston Astros used corked bats during the 2005 MLB season and 2005 World Series of which he was the manager. Rose had previously denied using corked bats.
