MLB veterans So Taguchi and Tadahito Iguchi both could be headed back to Japan next season.
Iguchi is said to be undecided about where he wants to play next year, but has expressed a strong desire in playing for Japan in the 2009 WBC (I don't think he's a lock to make the team though). Rakuten and his former organization Softbank have both hinted at interest.
Taguchi's option was unsurprisingly declined by the Phillies, so he'll be looking for work for next season. His former team Orix is watching the situation unfold, but not commenting on an acquisition yet. A return to Orix for a farewell season would be a nice ending for a guy that won one Japan Championship and two World Series Championships.
