The Cardinals consider Gregg Zaun a fallback option in their search for a backup catcher, tweets Joe Strauss of the St. Louis Post-Dispatch.

Assuming Matt Treanor and Henry Blanco finish expected deals, the backup catcher market could be down to Zaun, Josh Bard, Gerald Laird, and Molina if he's willing.
