Herrera (knee) played catch Tuesday, Daniel Guerrero of the St. Louis Post-Dispatch reports.

EDGE Analysis

It's his first bit of baseball activity since he landed on the 10-day injured list just over a week ago with a bone bruise in his left knee. Herrera will be brought along slowly, with the anticipation that he will be shelved for at least four weeks. Pedro Pages has been operating as the Cardinals' primary catcher in Herrera's stead.
