Hisashi Iwakuma spent New Year's in Hawaii and returned to Sendai on the 5th. While he originally planned to start his workouts on the 9th, Iwakuma was at Kleenex Stadium on Thursday for some running, catch (for about 30 minutes, with the new regulation baseball, at a distance of up to 50 meters), fielding practice, and weight lifting. Iwakuma arrived at the stadium a little past 10am and left around 5pm.
Masahiro Tanaka also showed up for a light round of exercises on Thursday. Tanaka was at Kleenex Stadium again today and spent about an hour on his workouts (playing catch, taking grounders, running). Like Iwakuma, Tanaka wasn't planning on practicing at Kleenex Stadium until later (apparently around the 20th it seems).
Hiromichi Fujiwara worked out at Kleenex Stadium on Thursday. Fujiwara had surgery on his left elbow back in June last year and is looking to make a comeback this.
