I picked up Trot Nixon a few years ago, the last time he was worth having on a major league team. I paid a substantially higher price to acquire his services, though; the Mets are only parting with cash or a PBTNL. For what it's worth, he was tearing it up and Tucson and Nixon is only 34, so I think he's worth a 15-game trial to see what's left in his bat. He also has the reputation of being a good guy to have in the clubhouse, so hopefully Nixon will bring some balls to a tepid Mets dugout.
I'll update the roster when it's confirmed who Nixon will be replacing, but the New York Post thinks it'll be Chris Aguila. I will simply suggest that if the only right-handed outfielder on the Mets roster is sent to New Orleans to make room for Nixon, while the third catcher is allowed to remain on the bench, it will be final proof that Omar Minaya is throwing darts at the wall to construct this roster.
I've seen it postulated that this move frees up Ramon Castro to DH in California next week, but is that really worth designating Aguila for assignment? Until Aguila clears waivers (assuming that no one claims him), the Mets have no right-handed hitting natural outfielders at the major league level. It's a sorry sad state of affairs when you honestly don't believe your team can afford to lose Chris Aguila.
Let's take a look at the active roster now:
Orlando "El Duque" Hernandez - DL
Billy Wagner (closer)
Matt Wise - DL
Moises Alou - DL
Ryan Church - DL
Angel Pagan - DL
