PHOENIX -- Last year, the Claw and the Antlers accompanied the Rangers all the way to the World Series. This October, we've seen the Brewers break out their Beast Mode.

Ladies and gentlemen, introducing the Snake.

"It's poisonous, you gotta be careful," D-backs catcher Miguel Montero said after its winning debut Tuesday in Game 3 of the National League Division Series. "Sneaky, too."

In the latest hand signal players are sending to their teammates after getting a big hit or making a big play, the D-backs broke out their own Tuesday, with Montero -- who invented the gesture -- delivering the first one when he reached second base with a first-inning RBI double that got Arizona rolling toward an 8-1 victory over the Brewers in Game 3.

"We came with that one today and it's a good one," Montero said. "I came in and I said, 'What about if we go with this one today?' and all the guys liked it. I got the double and boom, dropped it. We gotta use it, we gotta come back tomorrow and try to use it."

It's a simple sign, just one forearm up and the hand cocked forward like a snake's head, or something like the Bangles did in their "Walk Like an Egyptian" video back in the day.

The first appearance of the Snake actually came when first-base coach Eric Young made the sign during pregame introductions, giving the hand signal some play on the huge video board in center field at Chase Field.

Quite frankly, Montero was disappointed he was the first one to do it on the field, since leadoff hitter Willie Bloomquist was the first baserunner for the D-backs with a single off Brewers starter Shaun Marcum.

"We need to get Bloomquist going, he didn't do it," Montero said. "Come on, dude."

And so for all the pitching matchups and managerial maneuvers, it's down to this: Beast Mode versus the Snake for the right to advance to the NL Championship Series.

After such an impressive debut on the NLDS stage, the D-backs are eager to break it out some more in Game 4 on Wednesday and, they hope, in a decisive Game 5.

"Probably got to bite a couple more times to kill that monster," Montero said.
