According to MLB.com’s Matthew Leach, the Cardinals would love to upgrade their rotation and could do so via free agency. Ideally they would trade an outfielder for pitching, but the Cards are interested in pitchers with limited health risks willing to sign a short-term contract.
Leach confirmed with Jon Garland’s agent that the Cardinals "have called," but nothing has happened beyond that. Leach breaks down the chances that Andy Pettitte, Braden Looper, Randy Wolf, Odalis Perez, Ben Sheets or even Oliver Perez ends up in St. Louis.
The Cardinals appear unlikely to add a reliver or a second baseman.
