"We have been made aware of the allegation that has been made against Jung Ho Kang," Coonelly said in a statement. "We take allegations of this type extremely seriously. Pursuant to the Joint MLB/MLBPA Policy on such matters, this matter is exclusively before the Commissioner's Office at this time. We have and will continue to cooperate fully with the Commissioner's Office.
"As a result of the ongoing police investigation, we cannot comment further at this time. We have also advised our staff and our players that they should not comment on the matter either. We all need to be respectful to the police investigation of a very serious allegation."
Kang, a 29-year-old third baseman who signed with the Pirates out of South Korea last offseason, has not been charged with a crime.
