Re: Michael Lorenzen
I will never buy the idea that it makes sense to take a good arm and devote it to the bullpen without exhausting the idea of starting it first. Mechanics plays the biggest role for me. Bad mechanics that you can't change? Sure, bullpen. Otherwise, you put big arms in the rotation and hope it works out. If it hasn't by 23-24, you move them to the bullpen when they are already in AA and fast track them. If you have any kind of depth at all in your system, you can do that every single year.
Last year the Reds made the move with Partch and Ravin. This year it has been Lotzkar. Potential other options are Rogers, Smith, Crabbe and Renken (who was just moved to the bullpen). Contreras is going to be in the bullpen, though I think they really should explore the option of him as a starter longer.
