You need to get a real 1B. Also, don't carry two catchers. Considering how deep 1B is, it's sad you don't have a good one. What exactly happened in your draft?
Trevor Cahill has been subpar, Yu Darvish has problems with his control, Chris Sale has deadarm and will be getting more days off now. Lance Lynn is leveling out from his amazing start. Francisco Liriano is a joke imo and both Ryan Cook and Santiago Casilla could lose their closer jobs very soon.
If it were up to me, I'd drop Montero, Liriano, Cahill, and Howard. Definitely try to trade Lawrie for a SP when Longo gets back. I would throw in an OF as well since there are almost always some nice options on the waiver wire. So Lawrie+Cruz for SP or something like that.
