The New York Mets today announced that they have released 35-year-old second baseman Luis Castillo.The 5-11, 191-pound switch-hitter had one year left on his contract."This was baseball decision," said Mets General Manager Sandy Alderson. "I met with Terry (Collins) and made a recommendation to Jeff (Wilpon) and Jeff approved on behalf of ownership."Castillo was acquired by the Mets from the Minnesota Twins on July 30, 2007 for minor league catcher Drew Butera and minor league outfielder Dustin Martin.He has a .299 career average over 13 major league seasons with 194 doubles, 59 triples, 28 home runs, 443 RBI and 370 stolen bases. - LinkMore from Sandy via Rubin:“I don’t think there’s any question that there’s some linkage between his situation and a perception of the Mets that has existed to this point,” Alderson said. “That’s something that was taken into account. At some point, you have to make an organizational decision that goes beyond just an ability to play or not play. So those things are relevant. And you try not to make them so controlling that it dictates the final decision under any circumstances. Realistically, it’s a factor.”
