SWANSEA City are one step away from Wembley after beating Middlesbrough to move into the semi-finals of the Capital One Cup.
A Seb Hines own goal ten minutes from time settled the tie as he headed past Jason Steele from a Jonathan de Guzman corner.
The match had looked destined for extra-time before that, with an impressive Boro outfit proving difficult to break down.
There were few opportunities in the opening period, but the best fell to Tony Mowbray's side.
Boro skipper Grant Leadbitter went close on three occasions, his best effort beaten away by Gerhard Tremmel in the 36th minute.
Swansea had barely threatened, but upped the ante after the interval when Michael Laudrup introduced Luke Moore and Ki Sung-Yueng from the bench.
Moore looked to be hauled down by Andre Bikey when through on goal just before the hour, and with 15 minutes remaining Steele tipped Jonathan de Guzman's free-kick onto the bar.
Then, with time running out, a flurry of Swansea corners ended with Hines nodding into his own net under pressure from Garry Monk.
