Angels spokesman Tim Mead confirmed the Los Angeles Times' initial report Wednesday that Hamilton went to New York to meet with baseball officials. The team declined to give any more specific information.
Hamilton hasn't reported to spring training in Arizona after undergoing surgery on his right shoulder earlier this month. He is expected to be out until after the regular season begins.
The 2010 AL MVP is entering the third season of a five-year, $125 million contract. Hamilton has been a disappointment for the Angels, batting just .255 with 31 homers and 123 RBIs in two seasons.
Hamilton also has a well-chronicled history of drug addiction and alcohol abuse, leading to previous suspensions.
MLB declined comment on Hamilton.
