You give up the possibly good bat (but so far, pretty bad bat) for the almost sure thing OBP. Castillo has been very consistent. Plus you open up a spot in RF for Jake Fox, where you hopefully get that power back that you lose from Bradley's potential. If you wait till Aramis is back, I think this could be a nice money saving deal. You're not saving much money though. If Castillo were in the final year of his deal and we would have $9+ million each of the next two years to play with, I'd be for it. But to save $3 million and $6 million the next two years is not worth trading away the potential that Bradley has for, at best, a .350-.370 OBP. Bradley's OBP is already back up to .352 and he's slugging 50 points better than Castillo this year. Castillo has a much better batting average and 20 points higher OBP, that's it. Bradley is OPSing 28 points higher than Castillo right now. You're comparing what is supposed to be a power hitting RF to a light hitting, leadoff-type 2B though. The comparisons you should be making should be Jake Fox/Hoffpauir to Bradley, and Castillo to Fontenot/Blanco/Miles. I suspect in both cases those are going to be upgrades over the current numbers at both 2B and RF. Granted, Bradley has played way below his ability up to now this year, but with his injuries factored in...this would be a risk I'd be willing to take.
