5:55pm: Unable to work out a trade for a catcher, the Cardinals have made an offer to free agent Kelly Shoppach, according to Derrick Goold of the St. Louis Post-Dispatch (on Twitter). Shoppach opted out of his minor league deal with the Nationals earlier today.
2:52pm: The two sides have been unable to agree on a price, and the Cardinals' pursuit has slowed, tweets Rosenthal.
1:59pm: The Cardinals are in discussions with the Cubs to acquire Navarro, a source tells Ken Rosenthal of FOX Sports (on Twitter).
1:33pm: Sources say that a deal sending Dioner Navarro from the Cubs to the Cardinals is "possible" but not close, tweets Jayson Stark of ESPN.com (via Twitter).
12:08pm: The Cardinals are looking for catching with starter Yadier Molina likely to hit the DL with a knee injury, tweets Ken Rosenthal of FOX Sports, contrary to previous info he received. The Cardinals are concerned that Molina could miss a significant stretch of time to heal up, according to Derrick Goold of the St. Louis Post-Dispatch.
The Cardinals are gauging their options and how they can proceed once they know how long Molina will be sidelined for, Goold writes. The Cardinals have spent the past few weeks exploring deals for starting pitchers, relievers, and shortstops, but they have yet to explore deals for catchers. The catching market could include the Phillies' Carlos Ruiz and the Cubs' Dioner Navarro and Goold points that Miguel Olivo is a free agent after walking away from the Marlins.
