I like the idea of the Cubs looking for pen help, but I'm hoping that they don't have to give anything up to get it. If they do, I think they have the pen help already in the system and on the team. Ben Brown may be a high leverage guy. Hayden may be a good option for middle relief or high leverage situations. Horton may be able to give you some innings in high leverage situations starting in July.
I don't think it's time to panic just yet and they certainly need to clean up the pen, but it's not necessarily as bad as it looks as long as the SP is healthy.
