Swansea City brought Newcastle United's four-game winning run in the Premier League to a juddering halt with a 3-0 victory at the Liberty Stadium on Wednesday.
Substitute Nathan Dyer broke the deadlock with a volley on the stroke of half-time, with an own goal from Newcastle right-back Mathieu Debuchy and a late Jonjo Shelvey strike completing victory.
It was only a second win in seven home games for Michael Laudrup's side, who climbed two places to 11th in the standings, while Newcastle slipped one place to seventh.
Swansea recalled goalkeeper Michel Vorm after a knee injury, while Newcastle manager Alan Pardew kept faith with the team that had started in Saturday's 2-1 home win over West Bromwich Albion.
Loic Remy has been instrumental in Newcastle's fine recent run, but the French striker was denied a ninth goal in 10 league games when Vorm produced a tremendous flying save to push away his early header.
With Michu and Wilfried Bony still sidelined by injury, Alvaro Vasquez led the line for the hosts and he threatened to break the deadlock with an angled drive that flew narrowly wide.
It was to be the on-loan Getafe forward's last significant contribution, however, as he was forced to leave the fray shortly afterwards with an apparent groin injury.
Luckily for Swansea, Dyer proved a more than adequate replacement, volleying in the opening goal in first-half stoppage time after Newcastle goalkeeper Tim Krul could only palm an Alejandro Pozuelo cross into the air.
Dyer and Shelvey both threatened early in the second half, with Vorm thwarting Shola Ameobi at the other end, before Swansea doubled their advantage in the 67th minute.
Pozuelo dispatched a through ball for Shelvey to chase and although Krul blocked the former Liverpool midfielder's shot, the ball bounced off the unfortunate backtracking Debuchy and into the net.
Shelvey would not be prevented from writing his name on the score-sheet, however, and he capped victory in the 81st minute with a fine shot from 25 yards.
