The Cardinals will explore trades for bullpen help, GM John Mozeliak told Jim Bowden of MLB Network Radio (Twitter link). Mozeliak also said he has not had conversations with the Phillies about recently-designated lefty J.C. Romero and doesn't consider Romero an upgrade. On June 16th, Joe Strauss of the St. Louis Post-Dispatch had written that the Cards planned to investigate Romero's availability.
With a 3.94 ERA, the Cardinals' bullpen ranks 12th in the National League. The club was dealt a blow when Eduardo Sanchez hit the DL recently for a shoulder strain. The Cards still have a strong group of righties in Fernando Salas, Jason Motte, and Mitchell Boggs. I covered potentially available lefty relievers today, and the many right-handed relievers last week.
