Takehiro Ishikawa took a pitch off his right hand when he tried to hit an inside pitch during his at bat in the 7th inning on Wednesday night. Ishikawa got treatment for the hand and returned to the game and hit a single to center to finish out his at bat. He was then replaced by a pinch-runner.
Ishikawa was taken to a hospital during the game and was diagnosed with a fracture in his right pinky (右手第５指). He will likely require close to a month for a full recovery.
