Sunderland ran out comfortable 3-0 winners of Rotherham United in Tony Mowbray's first game in charge.
The Black Cats were frustrated in the first half as chances came and went - but made their superiority tell in the second period.
Two goals from Ross Stewart and a Jack Clarke goal gave Mowbray a win on his first match in the Stadium of Light dugout on a night when the Black Cats showed their potential.
