Wladimir Balentien was examined at a hospital in Tokyo today and diagnosed with a strain in his left adductor muscle. There is no timetable on his return. He could miss the start of the season. Balentien will begin his rehab at the Ni-gun facilities. The team will wait to make a final decision on him until they have had a chance to see him work out.
