From Newsday: ]The New York Mets are rumored to be considering three options at second base for 2008. Luis Castillo, Mets. They want him back, and he seemed happy during his brief stay. David Eckstein, St. Louis Cardinals. He's a free agent, and he probably could make a smooth transition from shortstop. Geoff Blum, San Diego Padres. A nice player, although his California roots probably will keep him with the Padres.
