Mets Targeting Livan Hernandez?

Ben Shpigel of the New York Times has some new Mets info for us today.

• Surprisingly, Shpigel believes the one free agent starter the Mets will seriously consider is Livan Hernandez.  That is odd because I had read Livan wasn’t high on Omar Minaya’s list.  We’ve seen the Mets connected to free agents Byung-Hyun Kim, Carlos Silva, Hiroki Kuroda, Kyle Lohse, and Jason Jennings so far this offseason.
• As far as some unsung trade opportunities, my Mets guy says Ervin Santana, Chris Capuano, Claudio Vargas, and Noah Lowry are being considered.
• According to Shpigel, the Mets hope to re-sign Ramon Castro as their backup catcher.  I don’t see that happening, as he’ll probably be able to snag a starting job elsewhere.  Options the Mets are considering to start at catcher include Yorvit Torrealba, Ramon Hernandez, Ronny Paulino, Gerald Laird, and Paul Lo Duca.  A source tells me the D’Backs’ Miguel Montero may also be on the radar.
• Shpigel says Luis Castillo might command a four-year deal.  Say what?  The Mets may yet re-sign Castillo but want to see what the trade market offers first.  Shpigel names Orlando Hudson, while I’ve also heard Alberto Callaspo.
