I didn't post this when it was new, but it's been widely reported that Tadahito Iguchi will decide his destination on the 20th, which is either tomorrow or later today depending on which timezone you happen to be in.
Bobby Valentine's Chiba Lotte Marines very publicly made Iguchi a three-year offer, and cleared out second base for him by releasing the incumbent Jose Ortiz. Despite this, Iguchi hasn't given up on an MLB contract, but given that the market for 2nd basemen (Orlando Hudson) has been so weak, his best financial offer is likely to be in Japan.
Update, Jan 19 8:11 am: According to 47news, Iguchi to Lotte is a done deal, and will be announced on the 20th. Other sources say the deal is close but not done.
