The Mets aren't yet pushing the panic button to replace Carlos Delgado, but that may eventually change. Delgado is expected to be out through the July 31 trade deadline and General Manager Omar Minaya will certainly explore external options to improve their defense and add some left-handed pop. Two possibilities are Baltimore?s Aubrey Huff and Washington?s Nick Johnson, two left-handed hitters playing for weak teams who, just as important, are in the final years of their contracts.
