[2/4/2017] Yomiuri Giants want Shun Yamaguchi to take things slow

Shun Yamaguchi started spring camp at San-gun because of discomfort in his right shoulder. No issues were discovered in the shoulder during an examination on February 2. He was hoping to join the Ichi-gun team during Okinawa camp, but the Yomiuri Giants are not going to rush him with a set schedule. The Giants believe he will be fine for opening day if he can pitch in one or two exhibition games.

Yamaguchi has played catch three days in a row. He is also up to fifteen meters on throws into a net. He could be ready to toss a bulpen session before the end of the month.

[UPDATE 3/4 @ 2:26am]

Yamaguchi may not be ready to join the Ichi-gun team until mid-April. His condition is improving, but the last thing the Giants want is for him to re-aggravate the shoulder.
