Ayumu Ishikawa had trouble throwing at full strength during his start against Softbank on July 24 (two runs, two innings). He continued to have problems during his next start against Nippon Ham on July 31 (ten runs, 0.2 innings). The Chiba Lotte Marines were concerned about fatigue and decided to skip him once in the rotation. The media recently learned that Ishikawa’s return will be delayed because he sprained his right ankle while running at Lotte Urawa Stadium on August 4. He might need about three weeks for a full recovery.
