Ryoichi Adachi is set to join the Ichi-gun team today. He could also make the starting line-up against Nippon Ham.
Adachi was hospitalized with ulcerative colitis on January 22. He was released from the hospital and began a rehab program on February 10. He played in his first rehab game at Ni-gun on April 2 and played full games on April 8 and 9. He started preparing for the active roster on April 10.
There are still concerns about his condition for night games — he is still not sure how his body will react and he is still working out how to prepare himself. If he is feeling fine, he could make the starting line-up tonight.
