MILWAUKEE -- The Brewers' brain trust met at Miller Park on Tuesday for a previously-scheduled monthly review. In light of recent devastating injuries, it might have taken a more urgent tone had someone other than steady general manager Doug Melvin been at the head of the table.

Instead, according to principal owner Mark Attanasio, who sat in, Melvin reviewed in order the team's pitching, defense and hitting. The tone, Attanasio said, was no different than similar sessions in Spring Training.

"I think that's really important, because that confidence gets transmitted to the players, the ownership and the fans," Attanasio said. "It's a very long season."

Already, it has been a trying season.

First baseman Mat Gamel, shortstop Alex Gonzalez and starting pitcher Chris Narveson are already lost for all or part of the season. Starters Zack Greinke and Shaun Marcum and reliever Francisco Rodriguez are heading toward free agency. In the coming weeks, the brain trust will have to decide what type of team it has.

"I think we have the nucleus to win," Attanasio said. "It seems like all teams add midseason pieces that they need to get over the hump. We now, unfortunately, have a couple of needs due to injury. Between here and midseason, some guys have an opportunity to step up, and then we'll see where we are at that point."

He did not entirely rule out becoming a seller at the July 31 nonwaiver Trade Deadline if circumstances demand it. Attanasio made clear he views that scenario as unlikely.

"We managed to surmount coming out of 12 years of losing to now having expectation to win, and I don't want to let that go," Attanasio said. "It's an ongoing challenge."

By Attanasio's count, the Brewers only have $59 million committed to 2013 salaries. That means they are in position to "go for players at midseason."

"We always have to do what's smartest for the organization, but the goal is to win," Attanasio said. "The only circumstance we would consider [selling off players] is where we had no choice of winning, and I don't see it. This team is too good to be in that position."

Melvin indicated that most clubs were still in evaluation mode, unwilling to consider trades. One possible target is the Padres' Jason Bartlett, but the Brewers are very wary of his poor play and his big contract. He is earning $5.5 million this season and has a $5.5 million option for 2013 that vests at 432 plate appearances.

As for free agents, the Brewers had contact with first baseman Derrek Lee's agent, but Melvin reiterated on Tuesday that there is no match.

"We're only 29 games into the season, there's a lot of baseball left, and with the additional playoff [team], a lot of teams are going to feel like they have a chance," Melvin said. "It's hard to replace those players. But that's what our Minor League system is for, and what our pro scouting is for, to see if we can find someone."

Players laud extensions for Melvin, Roenicke

MILWAUKEE -- Some of the Brewers' mainstay players said they were happy to see their bosses get some additional job security on Tuesday.

General manager Doug Melvin's contract was extended through 2015, and manager Ron Roenicke's through 2014, plus a club option.

"For both of those guys, it's well deserved," left fielder Ryan Braun said. "They've been instrumental in the success we've had to this point, being a smaller, mid-market team, making the playoffs two out of the last [four] years and drawing 3 million people to watch us play every year. Those guys deserve as much credit as anybody."

Braun is one of the players who has signed multiyear contracts of his own under Melvin. Braun is signed through at least 2020.

Continuity, he said, "is very important. For all of us, you look for consistency, you look for continuity and the challenge is longevity. Knowing those two pieces are going to be in place for at least the next few years, for us, as players, it's comforting and encouraging.

"And I think it helps in the offseason when you're going out and recruiting potential free agents or looking at trades, to be able to form a relationship with somebody and say, 'I'm going to be here for the next four or five years. I'm the one who you'll answer to. Whatever I tell you is going to stand.'"

Melvin has been Brewers' GM since September 2002. In his first full season, the Brewers spent the second overall pick in the Draft on Southern University second baseman Rickie Weeks, who since has become an All-Star. Weeks signed an extension with Milwaukee in 2011 Spring Training.

"I'm a big believer in being straightforward about things, and he definitely is that," Weeks said. "He never talks behind your back. He cares about players, but at the same time, if you're not doing your job, I think he'll tell you."

Last call

• The Brewers played under an open Miller Park roof on Tuesday for the first time this season -- at least that's what the box score will say. In reality, the dome began to close three batters into the first inning.

It was the Brewers' 14th home game, making this the second-latest date that the team played for the first time under an open dome. They didn't see the sky until the 23rd home game on May 29, 2008. The earliest it was open was 2010 Opening Day, on April 5 of that year.

• Left-hander Chris Narveson is back with the team after undergoing surgery last week for a partially torn left rotator cuff. He was relaxing in the clubhouse on Tuesday without a sling.

"The doctors say that's OK," he said. "You're trying to let the joint re-learn itself with natural movements. It's nice to be able to move a little bit."
