Impact Herrera had to be scratched from the Cardinals' lineup Saturday due to knee inflammation. He did some early-morning workouts Monday to test the knee and will continue with more activities to gauge his readiness to return to action. Herrera is projected to begin the season as St. Louis' primary designated hitter. He's also expected to be worked in at catcher, though it's possible the knee issue affects how often he's used behind the plate.
