PHOENIX -

The Milwaukee Brewers quietly put together one of the most productive offenses in baseball last season, leading the NL in runs, homers and RBIs.

They hope to do the same thing with a group that returns largely intact this season.

Ryan Braun, Aramis Ramirez and the rest of the key parts of last year's batting order are back in 2013, although Milwaukee may have to weather some injuries to key players.

Corey Hart is out until at least late-April following surgery on his right knee, Aramis Ramirez sustained a slight knee strain on Saturday, and Mat Gamel is out for the season after tearing the anterior cruciate ligament in his right knee for the second straight season.

Still, manager Ron Roenicke believes he has players to be productive again.
