MILWAUKEE – Javier Baez broke the code of silence when he mentioned to reporters the latest thing for a Cubs team that designed a Party Room for their state-of-the-art clubhouse at Wrigley Field, turned Jason Heyward’s Rain Delay Speech into World Series mythology and interviews each other in the dugout for pretend TV segments after hitting home runs.

“He doesn’t know how the Italian way works,” Anthony Rizzo said. “There are supposed to be team things that stay with the team.”

Baez let it slip before Friday’s game against the Milwaukee Brewers, replaying the dramatic 10-inning comeback victory from the night before at Miller Park. If you see the Cubs instantly disappear from the dugout, or a TV camera shows a shot of an empty dugout…

“We got this new thing,” Baez said. “I don’t want to be the one saying it. I’ll just let him say it. But it’s really fun. When somebody’s mad, everybody walks in and we do some fun things that get us hyper. You guys ask Rizzo.”

The Godfather gave a cryptic response. Omerta is expected to be part of The Cubs Way.

“It’s a team retreat,” Rizzo said. “It’s not just me. It’s anyone who needs to let out some steam this late in the season. It’s a team thing. It’s a long season and you go through ups and downs. And there’s times where you get to that boiling point where you just want to kill anything in your way.”

Rizzo needed to vent and called his teammates into the visiting clubhouse on Thursday night after striking out with two runners on in the eighth inning of a tie game that could swing the National League Central race.

“Throughout the year, you go back in the tunnel probably 25 times,” Rizzo said. “You got to take it out somewhere. You can only stay sane so long. It’s September. It’s a team (thing) now.

“It’s worked. We’re 3-for-3 on it. But it’s not me gathering. It’s just whoever feels like it’s time – you’ll see the team rushing off the bench and going for a nice little retreat.”

In many ways, Rizzo sets the clubhouse tone with his laid-back vibe off the field and intense competitive streak on the field. Tom Verducci’s book, “The Cubs Way,” detailed a scene before last year’s World Series Game 7 where Rizzo got naked, played “Rocky” music, quoted movie lines and shadowboxed until reliever Hector Rondon joined “in on the hijinks, picked up an aerosol can of shoe cleaner and sprayed it in the direction of Rizzo’s groin.”

“This is strictly in-game,” Rizzo said. “You can’t do it, though, and be selfish and go on a nice little retreat when we’re winning. It’s got to be the right timing. It helps, too, because it’s been fun the last couple weeks since we started doing it.”

One obvious benefit: There are no annoying TV cameras. Like in late July when frustrated pitcher John Lackey bumped into Rizzo in the Wrigley Field dugout and exchanged words with the face-of-the-franchise first baseman.

“We’ve come together now,” Rizzo said. “It’s not about anyone. It’s about us. When things go wrong for a certain individual, we rally around him. And that’s what we got to keep doing from here on out.”
