Ashley Barnes netted a late winner after Tom Heaton saved Dusan Tadic's penalty as Burnley beat Southampton 1-0 in the Barclays Premier League.
After an hour of the encounter at Turf Moor on Saturday, Heaton dived low to his left to keep out Tadic's spot-kick, and Barnes soon made the Serbian pay for his wastefulness.
With 17 minutes remaining, Barnes capitalised on hesitancy at the back from the visitors and, via a deflection off Toby Alderweireld, scored his second league goal of the campaign. His last - against Hull City last month - also came in a 1-0 victory at Turf Moor, and this success lifted Sean Dyche's men out of the bottom three.
For the visitors, defeat means they have now lost four consecutive matches after reverses against Manchester City, Arsenal and Manchester United, although Ronald Koeman's side maintain their fifth-place position in the table.
Burnley, meanwhile, extended their unbeaten home run to four matches with just their third victory of the campaign.
Jake Hesketh made his first start for Southampton, replacing Shane Long in the starting line-up, while the visitors' only other alteration from the 2-1 defeat against United saw Alderweireld return to the centre of defence in place of Maya Yoshida.
Burnley, unchanged from the 2-0 defeat at Queens Park Rangers, threatened twice in the opening three minutes through Danny Ings, who failed to make a telling connection to George Boyd's cross before flashing a 25-yard drive narrowly wide.
The home side went close to an opener again in the 26th minute when Southampton goalkeeper Fraser Forster reacted smartly after Nathaniel Clyne had deflected Kieran Trippier's cross goalwards under pressure from Barnes.
Hesketh, booked earlier for sliding in late on Heaton, saw his maiden start curtailed in the 32nd minute. Following a heavy collision with Michael Keane, the 18-year-old hobbled off and was replaced by James Ward-Prowse.
He made his first appearance since September having recovered from a fractured foot and soon tested Heaton with a low shot five minutes before the interval.
Following a quiet start to the second period, Sadio Mane sent his shot over the crossbar following some neat interplay from Southampton, who then passed up a golden opportunity to break the deadlock.
After Boyd had tripped Ryan Bertrand in the left-hand corner of the area, Tadic struck his penalty well but Heaton was equal to it to preserve his clean sheet.
Burnley responded, Ings forcing a smart low save from Forster before Barnes provided the crucial breakthrough.
Ings charged down Clyne's clearance and the ball ran kindly for his strike partner, who slotted beyond Forster with the help of a deflection off Alderweireld.
Clyne almost atoned for his part in the goal when he fired a drive narrowly past Heaton's right-hand post three minutes from time, but that proved to be Southampton's last meaningful effort as Burnley held on for a precious victory.
Burnley manager Sean Dyche: "We've had to dig in again. I thought in the first half we played very well and maybe surprised them a little bit.
"In the second half, they managed to grow into the game and we had to keep our resilience, shape and mentality to get the win.
"The penalty save was a massive moment. It is a penalty but we believe in Tom Heaton. He's made big saves for us before and has made that one today. It changed the feel of the game and our lads got back on the front foot. We responded well after that and delivered a good performance as the game went on."
Southampton manager Ronald Koeman: "Again the same story as last Monday against Manchester United. We had more chances, missed a penalty and one of our mistakes ended in 1-0. In my opinion, football is not that difficult but you can make it difficult.
"The difference between when we were winning games and are now losing them is a small detail like not punishing the opponent in a key moment like today. Also, doing more defensive mistakes.
"After a difficult start to the game, little by little we controlled the game. The story is to kill the game and we didn't. We paid for that. Everyone can make mistakes but too many goals in the last few games are from our own mistakes. We had enough chances to score but we didn't."
