Cishek's time as the Cubs' primary closer could soon be coming to an end, as Pedro Strop (hamstring) could be activated from the 10-day injured list as early Sunday, Bruce Levine of 670TheScore.com reports.

EDGE Analysis

Cishek has not allowed a run while notching a win and three saves with seven strikeouts in eight innings since Strop landed on the injured list, so he arguably deserves to remain in the mix for saves, but Strop could take back the bulk of those opportunities. The Cubs will decide after Strop's bullpen session Saturday whether to activate him or send him on a rehab assignment.
