The Red Sox will meet with Bobby Valentine about their managerial vacancy on Monday, according to a source close to the former Rangers and Mets skipper. Valentine, 61, has emerged as a possible front-runner for the Red Sox job after Boston elected not to offer a job to Dale Sveum, who on Friday became manager of the Cubs. He had a conversation with Red Sox CEO Larry Lucchino in 2003, before Terry Francona was hired.
