Goals from Lynden Gooch, Aiden McGeady and Max Power saw the Black Cats come from behind to pick up another crucial three points.
But who were the star performers, and who has work to do?
Our chief football writer Phil Smith has dished out his marks from the match – scroll down and flick through the pages of our picture gallery to see how each player fared:
1. Lee Burge
Made one good save from Moore with the scores level, and was quick off his line when needed. Little he could do about Henry’s fine strike. 6 Photo: FRANK REID 2020
2. Conor McLaughlin
Started well with some very good passing down the right to release Jones. A soft yellow card checked his progress and Oxford did cause him some problems. 6 Photo: FRANK REID 2020
3. Dion Sanderson
Not always convincing and got away with one or two errors, but stepped out with the ball well on occasions and got the job done. 7 Photo: FRANK REID 2019
4. Luke O'Nien
An absolutely superb performance at centre half. There were some difficult moments but he battled through and showed quality on the ball, playing a key role in the equaliser. Made one stunning defensive header late on. 8 Photo: FRANK REID 2020
