Williams under investigation following US Open final

6:04 am on 13 September 2011

Three-time US Open winner Serena Williams is under investigation by officials for the outburst she directed at the chair umpire during her loss to Australian Sam Stosur in the tournament's final on Sunday.

Williams was issued with a code violation for verbally abusing the umpire in the second set and faces further penalties, including a fine and suspension.

The tournament referee is reviewing the incident.

Williams is currently under probation for her foul-mouthed tirade during her 2009 US Open semi-final loss to eventual champion Kim Clijsters.
