This would be the perfect time to call up super-prospect Lastings Milledge - when the Mets don't need him. There's even a place for him to play - Xavier Nady was benched for yesterday's game, and Randolph insinuated that Nady may have more days off ahead of him. Nady hit just .217 in May. Why not call up Milledge to play some right field, and find out what the kid can do in the big-leagues? The Mets are winning now, and there wouldn't be a lot of pressure for Nady to produce, as opposed to if he were replacing one of the big guns like Beltran or even Floyd.
Milledge has got a .423 on-base percentage, and a .460 slugging percentage at AAA. Despite those lofty numbers, the Mets want to avoid Milledge being called up as a "savior". There would be no savior tag if he were called up at this juncture in the season, and no shame if he struggled in a one- or two- week stint for the big club.
Unfortunately, there doesn't seem to be any room on the roster, especially while the bullpen is called on so frequently. Mets relievers have pitched 170 innings in 48 games, more than any other club except for terrible Kansas City. The Mets are carrying twelve pitchers, and all seven relievers are getting plenty of work.
