Garrett Jones will return to the United States shortly. Jones never made it to the active roster this year. He had surgery on his left finger in April. He played in fifty-seven Ni-gun games and went 42-for-153 with a slash line of .275/.374/.523. He had some issues with his upper body in late-August and was training separately from the rest of the team. Jones will probably have a discussion with the Yomiuri Giants about what comes next.
