That was pretty bad. I can understand mistaking where the voice was coming from. I didn't realize Boone had gotten a warning prior to this. But, it isn't that difficult for the ump or MLB or whomever to simply say, hey, Wendlestedt simply thought the commentary came from the dugout, a warning had been issued, things played out live as they did, but upon review the ejection was a mistake. Ain't that hard.
As an aside, hey, the fan paid the admission, so he can say whatever he wants to whomever he wants, right?
