Sunderland surprised the play-off chasing 10-men of West Bromwich Albion to take a narrow away win at The Hawthorns in the Championship.
Baggies forward Brandon Thomas-Asante was sent off for two bookable offences late in the first half.
Four minutes later, Sunderland's Pierre Ekwah reacted first following a corner to smash the ball high into the goal.
West Brom stay fifth in the table, seven points inside the play-off places with three games left, with Sunderland 13th.
A cagey opening to the match saw very few clear chances created, with West Brom midfielder Alex Mowatt shooting over the bar from distance and Sunderland defender Luke O'Nien reacting brilliantly to clear the ball following a Baggies free-kick.
