Shun Yamaguchi twisted his left ankle during pitching practices at Tokyo Dome earlier today and was examined at a hospital in Tokyo. The Yokohama Bay Stars are waiting to see how Yamaguchi is feeling tomorrow before they make any decisions about his status, both for his next before the All-Star break and for the All-Star series.
[UPDATE 7/10 @ 9:37pm]
Yamaguchi was diagnosed with a sprained left ankle. It is uncertain how much time he will miss (he may have to miss the All-Star series).
