Substitute Will Grigg was denied a late winning goal by the outstretched toes of Swansea goalkeeper Kristoffer Nordfeldt as Wigan Athletic were held to their first goalless draw of the campaign at the DW Stadium.
Grigg was gifted the opportunity by an awful attempted Swansea backpass but, after steadying himself, his low shot was somehow diverted past the post by Nordfeldt.
The Northern Ireland striker was then unable to convert a teasing cross from fellow substitute Callum McManaman that was just inches too high for him, as Latics were unable to break through a determined rearguard.
At the other end, Christian Walton more than earned his clean sheet with several decent saves, before Chey Dunkley managed to deny OIi McBurnie a tap-in right at the death with a timely intervention.
The result sees Latics climb up a place to seventh in the Championship table, level on points with fifth-placed Brentford - five points behind leaders Leeds United.
And they may look back on this as a point gained with Swansea being arguably the best footballing side they’ve played all season.
There was early danger from the visitors as Connor Roberts almost found McBurnie only for Cedric Kipre to get in a fine sliding interception at the expense of a corner.
At the other end, great stuff down the right from Josh Windass led to a deep cross that was on its way to Joe Garner, before the last defender nodded it behind for a corner.
Swansea were playing some good stuff in the opening quarter, and there was a let-off for Latics when striker McBurney cut across goal and looked to have manufactured a tap-in for himself.
However, Reece James came out of nowhere to pull off a super block with the rebound falling to Barrie McKay, whose low shot was brilliantly saved by Walton.
Former Latics loanee Jay Fulton was seeing plenty of the ball for the Welsh side, and one of his crosses found Matty Grimes, whose blast from distance was parried out by Walton.
Another good opening for Swansea saw defender Roberts make his way through on goal, only to be denied again by a fine save from Walton.
Latics ended the half on top as James’ cross was volleyed just wide by Michael Jacobs.
And the home side were almost in inside 30 seconds of the restart, stand-in skipper Nick Powell’s cross from the right missing Garner in the centre and finding Jacobs coming in at the far post.
The shot, however, was again disappointingly wide of the mark.
Swansea regained control of the game and a really good move involving several players saw the ball dummied into the path of Fulton, whose shot was magnificently blocked by Kipre at full stretch.
Grigg took over from Garner just before the hour mark, and was immediately at the heart of everything Latics were offering.
After Leroy Fer fired wide for Swansea, Grigg was almost gifted the opening goal in slapstick circumstances, only to be denied by the goalkeeper’s heroics.
Latics also threw on Callum Connolly and McManaman, who almost created the opener with his first real touch, only for the ball to fly just too high for Grigg.
Credit Swansea, they weren’t content to hang for a point, and Bersant Celina forced a fabulous save from Walton, before Dunkley denied McBurnie with virtually the last kick.
