Sunderland signed off 2021 in style as they thrashed Sheffield Wednesday to climb to the top of the League One table.
Ross Stewart claimed his first Sunderland hat-trick as the Owls were comprehensively beaten, with Callum Doyle and Benji Kimpioka also scoring.
Sheffield Wednesday might have arrived on Wearside on the back of a 12-game unbeaten run in League One, but Sunderland effectively put the game to bed in the first half with three unanswered goals before the interval.
Stewart scored the first two of them, with his opening strike seeing him break beyond a dawdling Chey Dunkley to reach Leon Dajaku's through-ball and slot a low finish past Bailey Peacock-Farrell.
