Cardinals general manager John Mozeliak confirmed strong interest in retaining pending free agent shortstop Rafael Furcal. Mozeliak indicated Sunday he plans to "explore" a pre-emptive move within the next month. "When you look at our club since he came to our team, he's just really changed the look of it," Mozeliak said. "To try to find a way to get him back makes sense. But we have a lot of balls in the air. To try to balance it out financially and make it work is a challenge. But based on how he's played, and the type person he is and the energy's he brought to the club, there are a lot of positives." Mozeliak said he has not opened negotiations with Furcal's agent, Paul Kinzer, and abstained from saying when he might move on the matter.
