Media in Japan mention an ESPN article (an Insider article) that the Baltimore Orioles, Los Angeles Dodgers, New York Mets, Boston Red Sox, and San Francisco Giants all have interest in Hisanori Takahashi.
Ryota Igarashi was apparently advised by Daisuke Matsuzaka to take great care of his lower body because pitching on a harder mound can lead to muscle tightness. According to Hideki Okajima, things like running or spending time on a stationary bike after starts seem to help keep the muscles from tightening up too much.
Igarashi temporarily returned to Japan on Friday and will likely return to the US sometime around February 10th.
Akinori Iwamura will continue working out in Japan until early February.
