Sept 30 (Reuters) - West Ham United substitute Diafra Sakho scored a dramatic 89th-minute winner to secure a 1-0 Premier League victory over Swansea City on Saturday.
West Ham striker Andy Carroll hit the crossbar five minutes from time before Sakho stole in at the far post to lift West Ham out of the relegation zone.
The goal was the first Swansea have conceded away from home in the league this season and defeat left them in the bottom three. (Reporting by Sophie Hurcom, editing by Ed Osmond)
