As you may have seen earlier today via The Chicago Tibune, it turns out Sammy Sosa wasn't the only Cub who was corking his bat back in 2003.
During the infamous game in which Sosa broke his corked bat, MLB phoned the Cubs dugout and told them they had an hour to remove any other corked bats. According to reporter Fred Mitchell, the Cubs got rid of more than 70 corked bats.
Now if you know anything about physics, then you know the advantage of a corked bat is minimal at best. But still, that's considered cheating and that's a hell of a lot of cork. Even funnier is more than 50 of the corked bats belonged to Sosa. So they were just for batting practice, right Sammy?
Here's the original Trib article. And of course, here is Foul Balls take on it.
