I read this article and I for one believe it was a mistake. They test all of his bats (over 70 of them) even the ones in the Hall of Fame and None have any tampering.
The article also says that a corked bat does not help the ball travel more distance. In fact it normally will travel less distance.
You could tell that every one that's a hater here never played organized baseball.
It was a mistake none the less and he will pay for it with some type of suspension and fine as all the others in the past.
