Erik Miller (back) is throwing a bullpen on Wednesday and will pitch for Triple-A Sacramento on Sunday.

Miller was just placed on the injured list on Monday with a lower back strain, but he is already throwing and will be out on a rehab assignment quickly. He should return to the Giants when first eligible next week, which may put a little bit of a damper on the excitement about Caleb Kilian in fantasy leagues. Those two could share saves as part of a committee in San Francisco.
