Padres manager Bud Black suggested he doesn't expect Chase Headley (back) to play in Monday's series opener against the Giants. "The back is still bothering him," Black said. "He was making progress, and that has sort of reached a plateau." Headley was out of the lineup for the fourth straight game Sunday due to lower back stiffness. He remains day-to-day. Logan Forsythe and Alexi Amarista have been starting at third base in his absence.
