Sponichi notes that Hisashi Iwakuma returned to the US on 12/20 (after leaving Japan on 12/15) and told people close to him that he had a chance to meet directly with his agent and that they had a good conversation. Iwakuma plans to continue his workouts in Sendai while staying in touch with his agent.
According to Nikkan Sports, after workouts at Kleenex Stadium today, he told reporters he had a better feel for where things were heading and wanted to have everything decided before the end of the year. He also apparently met with a GM from one of the MLB teams during his trip to the US. It should also be noted that others reports mention that Iwakuma spoke to a number of GMs during his stay in the US.
Norichika Aoki worked out at Jingu Gaien today (like played some catch, took some BP) and told reporters the dates for his trip to the US have not yet been set.
