CHICAGO -- The Cubs have gone hi-tech.

The cheap disco ball hanging from a ceiling fan in the clubhouse is gone and in its place is a light and sound system that might rival Chicago's best dance clubs.

"Guys enjoy it," bench coach Davey Martinez said before the Cubs played the Pittsburgh Pirates Wednesday night. "They love it. We're having a lot of fun. It's synched up to music now too."

The disco starts up after each Cubs victory as their manager wants them to celebrate each win for 30 minutes. He mourns the losses for 30 as well and then it's on to the next game. But those 30 minutes after a win sound like a good time -- and now it'll be even more interesting with some strobe lights in place. Reporters were looking for the fog machine, in fact.

"I've seen a lot go on in a clubhouse but it's pretty fun in here," veteran catcher David Ross said. "We have a manager that encourages it and we have a bunch of young guys that like to act like a fool."

According to Martinez, Anthony Rizzo is the ringleader among the players.

"It has to be Rizzo," Martinez said. "He gets me going and once we get going it's all good."

Martinez says Pedro Strop and Dexter Fowler are the best dancers but he needs a few more victories to determine who the worst ones are.

"I'll get back to you on that," he laughed.

At 12-7 the Cubs are celebrating more than they're "staring at their lockers after games," as Joe Maddon put it. The front office is even OK with footing the cost for the new equipment.

"I like the fact they have a lot of fun," general manager Jed Hoyer said. "I know Joe (Maddon) and Davey (Martinez) really encourage it. Rizz is the ringleader. Hopefully we have a lot of chances to add some stuff. If it breaks the budget that's a good thing."

Head rubbing

You may have seen the Cubs rub their heads repeatedly whenever someone does something positive like get a big hit. It all stems from infielders Starlin Castro and Jonathan Herrera.

Herrera explains: "The real reason is it comes from Castro. We were talking one day and we said something funny and he just rubbed his head real fast. I said ‘why do you do that?' So that day when I got on-base it came natural to me to just rub my head. So now we keep doing it."

Castro didn't deny the story.
