This has gotten beyond frustrating. I don't think there are many "answers" there. But I'd make a few moves.

Right now:
Cozart up, DFA Renteria. This just has to be done sooner than later.
Dorn up, DFA...gasp, Fred Lewis (why haven't people been all over him? He's been terrible). This turns into a nice platoon with Dorn and Gomes. Never do these guys start vs. their non-platoon sided pitchers.

Give Boxberger a chance in Louisville to see if he could then help Reds in the pennant run. He's been dominating in AA right now. Could use bullpen help in chase.

Make trade packaging Alonso, Francisco, (keeping both in minors til then) and Ramon Hernandez for starting pitcher. Don't know who that pitcher is though. Bring up Mez in response to the trade.

Tear apart...
