Major League Baseball issued the following statement today:
"Major League Baseball takes all allegations of Domestic Violence seriously. When the allegations against Addison Russell became public on June 7, 2017, the Commissioner's Office's Department of Investigations immediately commenced an investigation. Melisa Russell declined to participate in the investigation at that time. Our investigation of this matter has remained open and we have continued our efforts to gather information. 
"With the new details revealed in today's blog post by Ms. Russell, Mr. Russell has been placed on Administrative Leave in accordance with the Joint MLB-MLBPA Domestic Violence Policy. We are hopeful that this new information will allow us to complete the investigation as promptly as possible."
