The Cubs swapped a little back-end bullpen depth Sunday morning, optioning lefty Randy Rosario to Triple-A and recalling righty Alec Mills. This gives them a reliever who’s a little more stretched out, which could be a need with a bullpen start Sunday and Jon Lester’s return still at least a few days off.
And the way things have gone with the ‘pen, the Cubs need to keep making some moves to see whether they can get someone to really take hold of the role. Or at least that’s the hope.
