Kentaro Nishimura was added to the active roster on June 2. Nishimura had surgery to remove loose cartilage in his right elbow in September last year. He spent most of his time rehabbing the elbow during spring camp.
Nishimura played in his first rehab game at San-gun in April. He moved up to Ni-gun on May 10 and pitch in five more rehab games before he was called up on June 2 (6.0 IP, 22 BF, 6 H, 1 BB, 6 SO, 1.50 ERA, 1.17 WHIP).
