Danny Graham struck four minutes from time as Swansea ended a memorable debut Barclays Premier League campaign with a 1-0 victory over Liverpool at the Liberty Stadium.
The striker fired low to Alexander Doni's left from Angel Rangel's astute ball across the box to give the Welsh side a win to rank alongside their successes over Arsenal and Manchester City earlier this term.
The hosts dominated the opening half and were denied by two excellent saves from Doni, who brilliantly kept out Gylfi Sigurdsson's free-kick and denied Nathan Dyer. The visitors proved more of a threat after the break with Michel Vorm making a stunning save from Andy Carroll's overhead kick before Graham struck.
Swansea bossed the opening exchanges, with Liverpool barely having a kick. Graham came close to giving them an eighth-minute lead but could not convert Joe Allen's cross-shot after the midfielder had robbed Jonjo Shelvey.
Maxi Rodriguez was off target with a half-hearted effort for the visitors but the majority of the action was taking place in the Liverpool half. Sigurdsson was left unmarked at a corner and almost swept home from Allen's pinpoint delivery but his effort was bravely blocked by the onrushing Liverpool defence.
Sigurdsson was brilliantly denied by Doni in the 32nd minute, as the Iceland international intelligently struck a free-kick across the Liverpool wall, but the Brazilian showed lightning reactions to tip the ball round the post.
Carroll wasted Liverpool's best chance when he fired narrowly over Vorm's bar five minutes before the break, while Dyer did the same for Swansea at the other end as Doni blocked his strike after being played in by Sigurdsson.
Liverpool boss Kenny Dalglish had his players out very early for the second half but any strong half-time words appeared to have little effect as Swansea again set about their familiar possession style. Dyer failed to make the most of good link work with Angel Rangel when he dallied after being picked out by the Spaniard's low pass.
Liverpool began to assert themselves as Carroll's far-post header diverted to safety off Steven Caulker's back, before the England forward produced a brilliant overhead kick that Vorm matched with a superb agile stop to his right.
Swansea showed signs of fading as the game entered its final 20 minutes, and Vorm made another sharp save from Carroll's low shot after a bright run from substitute Dirk Kuyt. But the hosts struck to find the winner as Rangel and Sinclair linked on the right and Graham converted coolly for his 14th goal of the season.
