When the Milwaukee Brewers take the field Tuesday night at Wrigley Field, it will be with their "A" team for the first time this season, as ace Ben Sheets returns and center fielder Mike Cameron makes his debut.

While Sheets — who missed his last start because of tightness in his right triceps — has demonstrated his worth this year with a 3-0 record and a 0.96 ERA in four starts, the unveiling of Cameron is the final piece in the Brewers' everyday puzzle.

"He's a solid defender, he's a great clubhouse guy, a great hitter," manager Ned Yost said in anticipation of Cameron's return from a 25-game suspension imposed during the offseason for his use of banned stimulants last year.

"He makes a good team better. It's a nice acquisition for us, to be able to put him in our lineup."

While the Brewers received some solid play from Gabe Kapler, Tony Gwynn and the now-departed Gabe Gross in Cameron's absence, Yost has relished the thought of Cameron in the No. 2 spot in a batting order seeking some renewal.

Cameron hit .325 with four home runs and nine RBIs in spring training. But more than his bat, Yost came away impressed with Cameron's all-around game and approach.

"He's a real positive clubhouse influence," Yost said. "He's another guy that fits into what we're doing, big time."

Cameron played his final tuneup with Class AAA Nashville against Colorado Springs on Monday night before reporting to Chicago for the three-game series with the Cubs. He went 0-for-4 and hit .200 with one home run and two RBIs in his four-game stint with the Sounds.

He spent most of the past month at Milwaukee's spring training site in Phoenix playing games against Brewers' farmhands at extended spring training.

Cameron also joined the club two weeks ago in St. Louis where he participated in pregame workouts before leaving Busch Stadium, as required by rules of the suspension.

The Brewers knew they would lose Cameron for the first 25 games when they signed him to a one-year, free-agent deal during the offseason. It was something they were willing to live with. However, after spring training ended, Yost expressed great admiration for Cameron and his aggressive style of play.

"We're going to miss him," he said at the time.

The Brewers survived, going 14-11 in Cameron's absence. They trail the first-place Cubs (16-9) by two games and are in third place in the National League Central standings.

Yost used Cameron, 35, in the second spot in the lineup throughout spring training and will have him there tonight.

"I like him on the bases in front of our big boppers," Yost said, referring to Ryan Braun and Prince Fielder.

"He's a guy that can turn a single into a double, a double into a triple, goes first to third on just about everything. He always increases your scoring possibilities with his baserunning."

Cameron also is considered one of the best ball hawks in center, a Gold Glove-caliber outfielder who should help shore up the middle of the Brewers' defense.
