Gibby goes bananas ... finally!

Well, we all knew it was just a matter of time.

Kirk Gibson went completely off on an umpire last night, and got tossed — then uttered a classic “I’m not going” when he was asked to leave the dugout so the game could continue.

It all went down in the bottom of the third inning last night, when Miguel Montero checked his swing — but was immediately told by plate umpire Bob Davidson that he’d gone too far (even though it was clear he probably didn’t offer, and at the least, there should’ve been an appeal to the third-base ump).

Gibby, known for his hot temper as a ballplayer, got immediately rung up for chirping from the dugout, then he went nose-to-nose with Davidson in a classic screaming match. It ended with some obscenities.

Then Gibson got back to the dugout and refused to leave momentarily, so Davidson refused to restart the game. The whole blowup lasted about two minutes, and is above.

After the game, Gibson had little to say about the situation — although he was in a decent mood, considering bench coach Alan Trammell managed the team to a 13-8 victory over the Cardinals to get the D-backs back to .500.

“We disagreed, obviously. I’m not gonna get into what was said and why, it’s pretty obvious,” Gibson sad afterward. “I just did what I had to do, OK? We had a disagreement. He’s been in the game a long time, I’ve been in the game a long time. That’s just the way it worked out.

“It’s probably smarter not to talk about it.”
