Wladimir Balentien was taken off active roster today with pain in his left Achilles tendon. He informed Junji Ogawa of the pain after Friday's game against Rakuten.
"It was something that has been bothering him for some time, so it can't be helped. We're not really sure how long he'll be out at this point," said Ogawa.
