With the frequency of broken bats, it is a stupid thing to do.
That's for sure!
I'll go further and say Sosa's finished.
Even in "forgiving" (it was only a little piece of cork, or it depends on the definition of cork) America, this assh@l& is toast.
Excellent point.
The prevalence of broken bats these days can be attributed to the prevalence of bats with super slim handles. If a pitched ball doesn't make contact with the fat of the bat, the skinny handles can't handle the stress and the bat breaks (usually in two distinct parts). I'd imagine the players favor this design because they think it gives them more power, but I think that reasoning is bogus. The bats used by players of old - Babe Ruth's being the most conspicuous example - had very thick handles, and his power obviously wasn't adversely affected. In more modern times, the power of 185 lb. Hank Aaron didn't seem to be adversely affected by his era's bat designs.
In an era of juiced baseballs, very advanced workout regimens, and super "supplements," Sosa is a complete loser for using a corked bat. So his well-struck home runs would travel only 470 feet instead of 510 ....big freakin' deal.
