Angel Rangel's late goal moved Swansea top of League One on goal difference above Leyton Orient, after beating Hartlepool at the Liberty Stadium.
Angel Rangel struck Swansea's winner eight minutes from full time
Pools seemed likely to share the spoils until a poor clearance fell to Rangel in the 82nd minute and he fired into the bottom corner through a crowd.
Swansea goalkeeper Dorus De Vries had to tip James Brown's shot onto the woodwork from a rare Pools attack.
Antony Sweeney also hit the home bar, but Rangel had the last say for Swans.
