SportsNavi is reporting that of the 87 players that had options for free agency, only 5 filed.
If you've been reading along, you already probably know, but for those that haven't, or need a re-fresher:
|Tasuku Hashimoto||Chiba Lotte Marines||Yokohama?||C||None|
|Atsushi Fujimoto||Hanshin Tigers||Yakult?||C||None|
|Shugo Fujii||Nippon Ham Fighters||???||C||None|
|Ryota Igarashi||Yakult Swallows||MLB||B?||Money / Player|
|Hisanori Takahashi||Yomiuri Giants||MLB||B?||None|
(The Tigers were initially interested in Fujii, but have since backed off.)
As you can see, I've also included information on the player's rank, as well as their compensation levels.
You can see my explanation of the Free Agency system for more information on how the ranks and compensations work.
