I also thought it was ball three and it was validated by the 2-2 count on the ESPN screen. It went to 3-2 after he had made his way down to first. Surprised all of the umpires missed that. And the Brewers.
What if that walk would have led to a game changing run, would the Brewers had valid reason to protest the game? Or would they pretty much have given that up not challenging it immediately after the play?
Once the next pitch was thrown, any appeal went out the window. But since Rolen hit into a double play on the *second* pitch thrown, I don't think the Brewers are complaining too much.
