The Mets could end up releasing Luis Castillo. New York has reportedly tried to trade the second baseman, but they have failed. Castillo is about to enter the last season of a four-year, $24 million deal and is owed $6 million for 2011. He posted a .604 OPS in 2011, which ranked 291st among 305 players with at least 250 plate appearances in the majors last year.
