I asked Baseball Prospectus's resident prospect guru Kevin Goldstein what he thought of the farmhands the Mets gave up in yesterday's trade with the Twins for Luis Castillo:
[Drew] Butera is a fine defensive catcher, but can't hit, he's a backup at best, and even that will take some work.Whatever Castillo brings to the team, it sounds like the Mets got their money's worth. The Mets expect Castillo to be in the lineup tonight when the Mets open their series in Milwaukee.[Dustin] Martin is a guy putting together a good year, but he's been a bit old for the level. He does have some tools and might have 4th outfielder possibilities. They didn't give up much.
