Lance Berkman (calf) was held off from a scheduled running session Sunday at Busch Stadium. Berkman told the St. Louis Post-Dispatch that he no longer feels any discomfort in his left calf, but team trainers felt his strain was not properly healed enough on Sunday morning to allow for jogging or sprinting. The hope is that the veteran first baseman will begin making steady progress this week. He's been on the disabled list since April 19. Matt Carpenter is filling in.
