An own goal and goals from Dominic Iorfa, Adam Reach and Steven Fletcher gave the Owls a deserved win, but who were the stand-outs on the day?
Take a look at our match ratings from a rout at the Riverside.
5. Sam Hutchinson - 7
Off for Luongo with a knock after 41 minutes. Did what he does - moved the ball onto people in better positions - and made some important interceptions. Photo: Pete Norton
6. Kadeem Harris - 7
Harris puts the fear of life into defenders with his pace, and it was clear Boro had set up to keep him quiet. Not at his more devastating best, but a constant threat. Photo: JPIMedia
7. Atdhe Nuhiu - 8
As auditions for a regular starting berth go, that was a good one. A constant handful for Boro alongside Fletcher. With Bannan's delivery, their physicality was the key component to a breathless first half. Photo: Pete Norton
