Oakland is one of the four teams to have inquired about Hisashi Iwakuma, but the A's are just "lukewarm" about the Japanese pitcher. The A's won the bidding for Iwakuma's posting fee last winter but were unable to come to terms with Iwakuma and his then-agent, Don Nomura, after negotiations that were at times testy. Iwakuma missed time last season with a shoulder injury, and he is now a free agent, with no posting fee required.
