Looks like Melvin is not interested in making at least one colossal blunder this offseason. From espn.com:
The Milwaukee Brewers are in the market for starting pitching this winter but GM Doug Melvin is telling rival GMs that he will not listen to offers for first baseman Prince Fielder.
Fielder is scheduled for free agency following the 2011 season and is set to make $10.5 million next season.
There were rumors this past season that the San Francisco Giants and Melvin had preliminary talks about a Matt Cain-for-Fielder swap, but apparently that idea is no longer a possibility.
