Swansea's Myles Peart-Harris impressed against the club he played for on loan last season
Swansea City fought back from 2-0 down to claim a draw in a thrilling game against bottom club Portsmouth.
Portsmouth looked on course for a second successive win – and just a third this season – after Matt Ritchie poked in his first goal for the club and Josh Murphy finished sharply from a tight angle.
But Swansea hauled themselves back into the contest just before half-time when Connor Ogilvie turned Liam Cullen's arcing cross into his own net.
Luke Williams' team dominated the second period, deservedly levelling thanks to Cullen's fourth goal in as many games for club and country after Myles Peart-Harris had hit the bar.
Swansea then missed a succession of chances to seal a comeback win - before Christian Saydee sliced wastefully wide at the other end.
The draw leaves Swansea 12th, yet Williams may feel this was an opportunity missed even though his team avoided defeat having gone behind for the first time this season.
Portsmouth have now lost just once in four games, leaving John Mousinho's team four points from safety with two games in hand.
While Swansea had been in action at Derby on Wednesday, this was Portsmouth's first outing in three weeks after the postponement of their fixtures against Blackburn Rovers and Millwall.
There were signs of Pompey's greater freshness during a first half in which their high press caused problems for Swansea.
The home side had plenty of possession but were rarely comfortable, with Portsmouth's approach paying dividends when Murphy dispossessed Josh Key and crossed low for ex-Newcastle winger Ritchie to score for the first time since moving to Fratton Park in the summer.
Portsmouth showed more ruthlessness to double their lead, as Ben Cabango's attempted pass was picked off by former Cardiff City player Murphy, and he surged into the area before netting for the third time in four games.
Swansea were wobbling, but gave themselves hope when Ogilvie, who was under pressure from Peart-Harris, diverted the ball beyond into the Portsmouth net.

Portsmouth appeared to change their tactics at the break, dropping deep for the first time, and the switch backfired.
Swansea should have been level when Key pulled back for Peart-Harris only for the former Portsmouth player's shot to come back off the bar, with Cullen's crisp follow-up saved by Nicolas Schmid.
The equaliser soon came, with Peart-Harris' driven cross from the right steered home by Cullen.
Swansea then wasted golden chances to find a winner, as substitute Eom Ji-Sung shot wide before Cullen's point-blank effort was brilliantly saved by Schmid.
Florian Bianchini was next to miss out, pulling wide as he ran through on goal, before Saydee skewed off target at the other end to bring the curtain down on a pulsating contest.
Swansea head coach Luke Williams:
"I love the players. I care about them enough to let them know that that's wrong, the way they approached the first half.
"They did come roaring back into it. They got forward in numbers and made a lot of box entries.
"The moral of the story is don’t be two goals down. Today we should have scored four goals, we scored two.
"Then you should come in and say 'we are a bit frustrated we didn’t score four, but we scored two and we won the game so it's okay'. But instead I have to come and say I am annoyed [because of the first-half performance].
"Portsmouth were excellent, the way pressed us, but we could have coped better. We made some bad decisions. Too many times we made the wrong decision under a lot of pressure."
Portsmouth head coach John Mousinho:
"It was a good game of football – plenty of entertainment, plenty of goals and chances.
"We were excellent first half. We really frustrated Swansea and scored a couple of goals. I thought we deserved the lead going into half-time – my big frustration was the way we conceded just before half-time.
"Second half was a different game. Swansea are a really good side – they cause sides plenty of problems and they really turned the screw.
"Overall we are pleased to take a point. Swansea will be disappointed they didn’t win."
