PITTSBURGH -- Brewers manager Ron Roenicke loves that his team is having fun, but he is a little concerned about the Monsters of Miller Park act going too far.

In recent weeks, the Brewers have been celebrating big hits by raising both arms in the air, a gesture that Prince Fielder says began with his kids imitating characters from the animated movie "Monsters, Inc." Fielder did it after driving in both of his runs in Sunday's win over the Mets, and teammates played along in the dugout.

Is Roenicke OK with it? Not really.

But before going to players with a request to tone things down, Roenicke consulted clubhouse veterans Craig Counsell and Mark Kotsay.

"I mentioned some things to them, I mentioned some things to a few guys. I don't want it to get carried away," Roenicke said. "Do I like it? Not particularly. But I don't think that I'm just going to come out and say, 'Don't do it again.' If I see it get worse, and I see it being a problem, then I'll talk to the guys about it."

Players insist the gesture is not meant to show up the opposition and say they are just having fun. The Rangers made similar celebrations popular last season with the "claw" and "antlers" gestures, all the way to the World Series.

"Today's game is just different," Roenicke said. "If you want to be 'old school,' you're not going to do real well in this game today unless you've been around as long as Tony La Russa or [Bobby] Cox last year. Then it's a little different, because ... they've earned the respect that they can make that call. I have not."

Outfielder Nyjer Morgan referred to the Brewers' gestures in the Milwaukee Journal Sentinel as "beast mode," and understands there is a fine line between having fun and disrespect.

"We don't want to show up anybody," Morgan said, "and we don't want to seem like we're out there being cocky and don't respect someone else's game, or the game in general. If it comes down to that, guys are going to have to turn things down. I think it's cool."

"Our personality is different than everybody else's," said another "beast," right fielder Corey Hart. "I think it's good if other teams don't like it."

Braun off and running for Brewers

PITTSBURGH -- Ryan Braun stole two bases in Sunday's win over the Mets and wanted to try for a third, a sure sign that the left leg injury that lingered through July and early August isn't lingering anymore.

Braun had six steals in his last 11 games through Sunday and leads the Brewers with 26 swipes this season, a career high. He's almost always running with cleanup man Prince Fielder at the plate, so manager Ron Roenicke is helping Braun pick the right spots.

"I'm kind of controlling that for him," Roenicke said. "I don't want him going out there thinking, 'Hey, is this a good time to steal, because if I steal they're going to walk Prince?' I don't want him to think about that, so I've taken that away from him."

Sometimes, Roenicke gives Braun the stop sign. Sometimes, he gives a suggested steal sign. Sometimes, he gives Braun the green light to decide himself.

The decision depends on the inning, the score and whether opponents are shifting against Fielder.

"I just don't want him to question whether he should go or not, and I don't want Prince going, 'Why is Brauny going?'" Roenicke said. "So I've talked with Prince and told him, 'Listen, I'll control when I want him to go or not, and I am thinking about your situation.' I told him all the reasons why, and he's fine with it."

Estrada readies for move back to bullpen

PITTSBURGH -- Right-hander Marco Estrada will make his seventh Brewers start on Tuesday against the Pirates. And then? Well, he's not exactly sure.

Estrada will probably head back to the bullpen since left-hander Chris Narveson returned from the disabled list for Monday's doubleheader at PNC Park. Estrada had been filling a spot in the starting rotation while Narveson recovered from a cut on his left thumb.

"If Narveson is good, then that's probably what's going to happen," Estrada said. "I would love to stay a starter, but this could be my last start. It's not tough. I don't mind doing either thing. I'm more prepared now to start, and I'm going to have to change my mindset if and when I go back. I have to find it again."

That's life for a long man.

"It's fine," Estrada said. "I'm here. I'm in the big leagues and I'll do whatever it takes to stay here, whether it's starting, relieving, batboy. Whatever."

Assuming no setbacks for Narveson, Estrada would probably return to the bullpen for the Brewers-Cubs series at Miller Park beginning Friday. Brewers manager Ron Roenicke and pitching coach Rick Kranitz must decide whether to start Narveson or Monday's Game 2 starter, Zack Greinke, in Sunday's series finale and who to hold all the way until Tuesday, the opener of a key series against the second-place Cardinals.

Last call

• According to manager Ron Roenicke, the Brewers opted against summoning a pitcher from Triple-A Nashville to Pittsburgh as insurance during their doubleheader. They briefly considered bringing someone in, just in case a player move was necessitated between games.

• The Brewers' Dominican League team began a playoff series against the Orioles' entry on Monday, but the game was suspended in the fourth inning with the Brewers leading, 3-1, because of weather associated with Hurricane Irene. The Dominican Brewers won a Wild Card spot by going 44-27 in the regular season.
