Tomoaki Egawa (Softbank) was taken off the active roster today after he was diagnosed with a sprained left thumb. There is no timetable for his return. He suffered the injury during his at bat in the 1st inning of Friday's game against Lotte.
The Hiroshima Carp decided to take Yusuke Nomura off the active roster today because of his struggles so far this season -- in two starts he gave up eight runs (seven earned) on fifteen hits and three walks over ten innings of work. He also has some tightness in his right shoulder.
Pitching coach Yasuyuki Yamauchi on Nomura: "He has some tightness in his shoulder and there might be something wrong with his mechanics. We are also concerned about him mentally [since he has not won a game since August 2012]."
