I was slightly exagerrating. What the article does do is provide a sanity check to the people saying every one of his homers is suspect. Or his whole career is a sham, etc.
What it says is that yes, Sosa broke a rule and should be punished, but corking a bat is not only illegal, it;s stupid!
So yes, Sosa should be punished, but the 10 game suspensions they've given before seem to be about what the offense deserves. It's not steroids, and it's not betting on baseball.
Sosa screwed up. I'm pretty sure he did it intentionally, but it doesn't matter that much either way according to physics. At least not as much as I thought.
Still, no player should even be allowed to use a corked bat in BP. They shouldn't be allowed in MLB parks. Right under "No Cricket." (drawing a blank. Is that what they say?) They should have "No Corked Bats".
