MLB has begun investigating the domestic assault charges against Red Sox pitcher Steven Wright. The commissioner's office has independent authority to review such matters under its joint domestic violence policy. MLB suspended Aroldis Chapman for 30 games in 2016 even though criminal charges weren't filed against him. Derek Norris was banned for the final month of the 2017 season after allegations of physical and mental abuse by his ex-fiancée.
