Tony Mowbray’s side took an early lead when Dan Ballard headed home Alex Pritchard’s in-swinging corner in the 5th minute, before Jack Clarke added a second two minutes later.
Clarke then scored again from the penalty spot in the 31st minute following a foul on Mason Burstow in the box.
Here’s how Phil Smith rated the Sunderland players at Hillsborough:
1. Anthony Patterson - 7
Had next to nothing to do but made a smart stop to deny Paterson when called upon in the early stages of the second half, and one fine block in stoppage time. 7 Photo: Frank Reid
2. Trai Hume - 7
An accomplished showing, combining nicely with Roberts down the right and finding Burstow for the penalty that led to Sunderland’s third. Defensively as robust as we’ve come to expect. 7 Photo: Frank Reid
3. Dan Ballard - 8
Took his goal very well and it will be a big boost for Sunderland if he can keep contributing. Rarely troubled defensively, and dominant when required. 8 Photo: Frank Reid
4. Luke O’Nien - 8
Good in possession and though Wednesday rarely threatened, he was always there to snuff out the danger when they did. 8 Photo: Frank Reid
