SAN FRANCISCO — It's not a huge surprise that Yadier Molina isn't the starting catcher for the St. Louis Cardinals in Game 3 of the National League Championship Series. Molina's strained left oblique has his postseason in question, even though Cardinals manager Mike Matheny hasn't officially ruled Molina out , instead calling his status "day to day." Molina's replacement in the starting lineup Tuesday, however, is ripe with storylines. A.J. Pierzynski, the well-traveled lightning rod of a backstop, will catch for the Cardinals and bat sixth. The Cardinals signed him when Molina hurt his thumb in July, two weeks after being released by the Boston Red Sox.
