The Mets have insisted for months that they won't trade their top position prospect, Lastings Milledge, but more and more major-league executives believe that the Mets will indeed part with Milledge, 21, if they can get the right starting pitcher in return. Dontrelle Willis is their primary target, but the Marlins hold his rights until 2009 and would demand much more than just Milledge. Barry Zito, a potential free agent, would be a more realistic target ? the A's previously have indicated they would be willing to move Zito for a package of Milledge and Mets right-hander Aaron Heilman. The Giants have made it clear that they are not interested in trading Jason Schmidt, but perhaps they would listen if they had a chance to acquire Milledge.
