According to Sports Hochi, the Tigers are prepared to wait on Igarashi as long as they feel they have a chance.  They have already reached out to his agent and are currently confirming a number of things like basic contract terms.  The team is also looking into foreign players but will hold off on them as long as possible -- their top priority continues to be Japanese players returning from the Majors.  Source: Sports Hochi 10/31/2012, Sports Hochi Osaka 10/31/2012

Nikkan Sports reports that the Tigers feel they will have a better idea of where they stand on Tsuyoshi Nishioka (expected to sign), Kosuke Fukduome (still uncertain), and Ryota Igarashi (still uncertain) before the end of the year.  Source: Nikkan Sports 10/31/2012
