The Tigers are planning to look into domestic free agents that require no compensation. One such player could be Kenichi Nakata -- he earned his domestic option in August and will be a C level free agent.

According to a Daily Sports report on Sunday, the Chiba Lotte Marines are planning to look into Alex Ramirez.
The Marines are looking for a right-handed bat that can provide some pop. They feel Ramirez might fit the bill: they know he can be a liability on defense, but feel he still has enough left in the tank to help the team with his bat. They also think signing him would be less of a risk than a player that has no experience in the NPB. Plus, they like his potential marketability.
