Possible Castillo replacment?

I know I've said that I'm willing to give Luis Castillo a clean slate this season. He showed up to camp in great shape and has put together a great spring. But deep down, I'm still worried about how his knees will hold up and if he can still perform up to his contract and at the major league level.

The Mets are particularly thin at the second base position through the minor leagues, but Jonathon Malo had been impressing Jerry Manuel -- until he was sent down to minor league camp.

And as scant a chance as Green had, it was diminished by the late emergence of Jonathan Malo, a 25-year-old Canadian-born second baseman who has impressed Manuel to such a degree that the manager has told people in the organization that Malo is among his favorites among the possible reserves. But there seems to be no place for Malo on the roster.

Very interesting. Manuel doesn't really keep up with a lot of the minor leaguers, so it's especially telling if he said something to this degree.

Keep on eye on Malo to see if he can play. I wouldn't mind seeing if the Mets can find a suitor for Castillo midway through the season.
