Non-tender Castro, and eat his contract. Gookie can do what castro does defensively, and has more range. Plus it allows him to develop a little at the major league level. When people rant about Bowden abusing young pitchers, I should point out he abused Gookie in 2001(?) when Larkin was hurt.---TRF
I've written similar words in the past myself, TRF. You can't 'non-tender Juan because he already has a contract, but you can cut him. While it would be unpalitable for the Reds, eating Castro's contract would allow the Reds to keep Gookie (who at least has potential). It's likely that someone would pick up JC's contract for the league minimum (with the Reds paying the balance) so, with Gookie making only slightly more than the minimum, the thing is pretty much a wash.
And, I also thought that calling up Gookie and then setting him on the bench when Larkin was hurt was a major turning point in Gookie's development.
