03/01/2017 20:00 v Crystal Palace
Angel Rangel scored a dramatic late winner as the Swans moved to within a point of safety thanks to a 2-1 win at Crystal Palace.
The Swans, who had named Paul Clement as their new head coach earlier in the day, claimed a first away win since the opening day victory at Burnley.
It came thanks to Rangel's 89th-minute effort, with the Spaniard latching onto fellow sub Leroy Fer's chipped pass before beating the advancing Wayne Hennessey.
It was just reward for the Swans, who had taken a first half lead thanks to Alfie Mawson's first goal for the club.
Wilfried Zaha looked to have pinched a point for the hosts, but Rangel's late heroics ensured the Swans claimed a league double over Palace.
The win means the Swans moved onto 15 points and into joint 18th - one point off the Eagles.
The Swans were full of energy and had plenty of attacking intent in the first half.
The visitors created an early chance through Wayne Routledge, whose cross found Fernando Llorente only for the striker's header to bounce just wide of the far post.
And the chances kept coming as a swift counter, started by some fine work from Routledge, saw Llorente surge forward to tee up Jack Cork, but he was denied by the onrushing Hennessey.
From the resulting corner - a replica of the one that saw Llorente score against Sunderland - Sigurdsson fired low to Ki Sung-Yueng, but the South Korean's first-time effort fizzed wide.
The warning signs were there for Palace, and the Swans kept plugging away.
Federico Fernandez was the latest to try his luck, only for the defender to rise highest but nod Sigrdsson's free-kick over the crossbar.
Buoyed by their fine start, the Swans continued to look for the opening goal, and it took another stop from Hennessey to deny Routledge after he latched on to Mawson's finely-threaded crossfield pass.
Despite that, the Swans almost wasted their decent start as a long punt upfield from Hennessey bounced twice before the onrushing Benteke latched onto it. Out came Lukasz Fabianski, down went Benteke. But referee Paul Tierney waved away the appeals.
After that brief foray, the Swans finally got the goal they deserved after 42 minutes.
After Ki was awarded a free-kick down the Swans' left, Sigurdsson swung in the delivery and Mawson headed into the far corner for his first goal for the club.
That was the last real action of the half, with the Swans holding a deserved lead.
The second half belonged to Palace in terms of chances, territory and possession.
Forced into a change at the break, the hosts sent on Fraizer Campbell in place of Benteke.
He gave Palace more energy up front, but it was Zaha that was their main menace going forward.
After soaking up waves of pressure from the hosts, the Swans were digging deep to preserve their lead.
But that ended with seven minutes left, with Zaha volleying home a stunning effort from Martin Kelly's cross.
It could have been enough to have knocked the wind out of the Swans, but, like the corresponding fixture at the Liberty, there was more drama to come.
Sub Leroy Fer dinked over a chipped pass on to fellow sub Rangel, and the Spaniard controlled well before guiding his effort past the advancing Hennessey.
The Swans had to hold on for five minutes of added time, and they did just that to move to within a point of 17th-placed Palace.
