How is it that the Oakland A’s lead the world in back injuries? Are the post game spreads that heavy to lift? Is it whiplash caused by watching the line drives hit off our new ace Joe Blanton? Whatever the cause, the Athletics could keep a lineup of chiropractors in clover. This week it’s Eric Chavez disabled indefinitely due to damaged discs. Being an A’s follower has made me more hip to epidurals than ERAs.
