I'd try trading Flores to the Tigers with Bobby Parnell for Nick Castellanos. Detroit has moved him to LF because Cabrera is playing 3B. That takes care of one of the Mets major needs. The Tigers have asked about Parnell in a trade because they really need bullpen help. Lets face it... the Mets chances of competing in 2013 aren't all that great and they have a good number of young pitchers coming up in the minors who can be used in the BP.
Cabrera really helped Avisail Garcia (2013 Tigers LF?) develop so maybe he can influence Flores as well. Garcia and Flores are very similar in style except Garcia is much faster. Bottom line is.... Castellanos looks like the real deal and could be a big piece of the Mets future.
