Source: Cubs sign C Navarro

The Chicago Cubs signed catcher Dioner Navarro, a source familiar with the situation told ESPNChicago.com's Bruce Levine.

Navarro, a former All-Star with the Tampa Bay Rays in 2008, spent much of last season in the Cincinnati Reds' minor-league system. He played 24 games with the major league team and hit .290.

Welington Castillo and Steve Clevenger are expected to battle for the Cubs' starting spot next season.
