One of his representatives told owner John Henry that Ramirez again wanted to be sent to a different team and wouldn't report to spring training, a team source told The Boston Globe.
Ramirez has the veteran right to block a trade to a team he doesn't like, and Gene Mato said the slugger might change his mind during the process, the paper reported.
General manager Theo Epstein declined to comment on the reported trade request.
''Manny, his representatives, and the Red Sox have open lines of communication and will throughout the offseason," he told the Globe. "I think we all want whatever is in the club's best interest and Manny's best interest."
