Being based in Japan half the year I have some interest in this. There doesn't appear to be much avaiable that fills needs for the Tigers. I perceive those as 3B, 2B SS and Right handed OF. Pitchers from Japan are available and you can never have enough.

Problem being he is a CF and left handed. But it would open up players to be traded to fill other needs..
