Sunderland moved to within a point of the play-off places as they came from behind to beat Birmingham City at the Stadium of Light. George Hall put the Blues in front on the half-hour, but Trai Hume levelled in first-half stoppage time.
And with 15 minutes remaining, Amad scored his 12th goal of the season to complete the turnaround and put the Black Cats ahead. There was more work for Sunderland to do however, with defender Dennis Cirkin sent off for a second bookable offence just a couple of minutes after Amad's goal.
And that meant the Wearsiders had to hold on for dear life in the final stages as Birmingham threw everything forward to try to salvage a point. But Sunderland stood firm to claim their first home win since February, completing back-to-back wins in the process following their Easter Monday victory at Cardiff City, and stay firmly in the play-off race.
