The Padres optioned Jacob to Triple-A El Paso on Thursday.

Jacob struck out three and gave up a hit over a scoreless 22-pitch inning of relief in Wednesday's loss to the Pirates. Though Jacob likely would have been available for Thursday's series finale in Pittsburgh, the San Diego bullpen as a whole had been used heavily of late, so he was the odd man out as the Padres called up a fresh long-relief arm in Carl Edwards from El Paso.
