BTW - Brownie, who decided to play Bill Brown P.I., gave his interpretation of why Berkman was tossed. It goes like this:
As Berkman runs towards first (I use run loosely here), he notices that Rapuano calls him out on a swinging strike.
Berkman screams "No way, No way!" and walks towards Rapuano.
Rapuano (according to Brownie) then motioned to the Astros bench while moving towards Berkman and (again, according to Brownie) says "Get back to the bench!".
Berkman goes crazy *thinking* that Rapuano was tossing him, when in fact he was merely saying with his actions and words that he had no inclination to discuss anything with Lance.
Rapuano notices that Berkman is now animated rushing towards him so he then tosses him.
In short, Berkman mistook the umpire's direction and in essence got tossed after the fact. No word if Brownie has any information to share on the grassy knoll and JFK, but juneberno!
