To clarify Bud Selig's released statement, an anonymous baseball official has confirmed that there will be no reversal of the call that cost Armando Galarraga his perfect game. Selig apparently decided not to reverse the call because of concerns with the precedent it would set and because he didn’t think it was practical.
To me, this is a very cowardly move by Selig. This whole situation could have easily been fixed by simply reversing a call that would not have changed the outcome of the game. This was definitely expected out of Selig, but I was hoping to be surprised.
