  WHAT A CORKER! Would someone please explain to me why Sammy Sosa would use a corked bat in practice ? A piece of cork was found just above the handle in Sosa's bat Tuesday night when it shattered after he grounded out in the first inning of the Chicago Cubs' 3-2 victory. Sosa didn't deny the corked bat was his, but he said it was a batting practice model that he had grabbed by accident.
