I really believe if he had the impression he could play with the Sox this year, he wouldn't have left for Japan. I am sure he had a discussion with the team before he left about his status. For whatever reason, he felt his chances were more realistic in Japan. My guess is that he would have asked if he had a chance, and the Sox must have told him no. He must be behind enough guys on the depth chart that he didn't have a shot at the major league roster this year.
