...Hiroyuki Kobayashi was removed from the Ichi-gun opening day rosters on Wednesday due to tightness in his right elbow. Seems Kobayashi felt some discomfort in his elbow after pitching on consecutive days (the 10th and 11th). Kobayashi told reporters that he'd like to make a return to Ichi-gun by the 27th, when the Marines return to Chiba for their home opener against the Nippon Ham Fighters.
Until he returns, the Marines will likely turn to Yasuhiko Yabuta to close out games. If that doesn't work out, then closer by committee.
