Athletics placed OF Coco Crisp on the 15-day disabled list, retroactive to April 30, with a left hamstring strain. Crisp suffered the injury during Monday's extra-inning win over the Angels. It didn't appear to be all that serious at first, but he'll now be sidelined until around mid-May. Yeonis Cespedes figures to play center field until Chris Young is ready to return to the lineup.
