Sponichi mentions that the Texas Rangers may be interested in Ryota Igarashi.
Via the Star Telegram:
The Rangers have been linked, though possibly as a byproduct of their recent attempts to woo Japanese players, to right-handed reliever Ryota Igarashi. He has expressed a desire to play in the United States in 2010 and is believed to be the top Japanese player available to big-league teams this off-season.
Not really sure if that's enough to say that the Rangers are really interested, but I suppose it's a start.
