Takayuki Kishi (SEI) joined the Ichi-gun roster for practice (running, playing catch) yesterday.
The current plan for Kishi involves providing the bullpen with some help. Brian Sikorski has had problems with tightness in his right elbow and the team doesn't want to push him too hard by having him throw on consecutive days. So if Sikorski is needed to close out tonight's game, the Lions still have an Kishi to turn to tomorrow.
The Lions were probably hoping Alex Graman could help pick-up the slack, but he's been largely ineffective, giving up 5 runs (all earned) in two relief appearances (0.2 IP).
