Pierzynski to sign with Cardinals Free agent catcher A.J. Pierzynski will sign with the St. Louis Cardinalsto give the team an additional backstop while All-Star Yadier Molina recovers from thumb surgery, according to St. Louis Post-Dispatch.

The 37-year-old Pierzynski was released by the Boston Red Sox earlier this month after batting .254 with four home runs and 31 RBIs in 72 games. The Cardinals will pay him the pro-rated portion of the league minimum salary.
