Yoshio Itoi was replaced by a pinch-runner after he led off the sixth inning with a single to center during tonight’s game against the Softbank Hawks at YafuOku Dome. He and a team trainer were later seen leaving the stadium. He had an ice pack wrapped around his left hamstring.
[UPDATE 6/10 @ 10:45pm]
Itoi was diagnosed with a mild strain in his left hamstring. He will remain on the active roster for the time being.
[UPDATE 6/13 @ 2:36pm]
Itoi might not be ready to return to the starting line-up until after Inter-league play ends. He had a follow-up exam on June 12 to check his progress.
