The Hanshin Tigers appear to be preparing for the possible returns of Kenshin Kawakami and Hiroki Kuroda. The Tigers apparently have their international scout taking a look at the two pitchers (in addition to other MLB players).
Kuroda is in the final year of a three year deal and is favored to return to Hiroshima if / when he does decide to return to the NPB. But the Tigers feel they have a shot if they show Kuroda just how interested they are in him (and showing interest now certainly couldn't hurt either).
Kawakami is still in the second year of a three year deal, but with the way in which Kenji Jojima joined the team this year, the Tigers feel they have a shot with him as well.
UPDATE: it appears Kosuke Fukudome is also on the Tigers' radar.
