Dunfermline Athletic 1-2 Greenock Morton

A goal by substitute Jai Quitongo with five minutes left gave Greenock Morton a Scottish Cup win over Championship rivals Dunfermline Athletic.

Frank Ross, making his debut on loan from Aberdeen, found Gary Oliver with a chip over the home defence and the forward volleyed into the far corner.

Dunfermline equalised after the break when Declan McManus fired home against his former team-mates.

But Quitongo's superb finish into the far corner won it for Morton.

The visitors were without a win in their last three matches, but they were unbeaten against their hosts in two league games this season and began the cup tie on the front foot.

Gary Harkins blasted high over the crossbar before goalkeeper Lee Robinson did well to push a flick from Oliver on to a post.

Dunfermline slowly eased their way into the game and McManus forced goalkeeper Derek Gaston into a fine save then Nicky Clark headed just wide.

Jim Duffy's visitors kept pushing forward and stunned the home side when they took the lead, former Hearts striker Oliver firing an angled shot across the Pars goalkeeper.

Tackles were beginning to fly and home defender Nat Wedderburn was lucky only to receive a yellow card from referee Alan Muir after a late challenge that caught Harkins high up in his thigh.

The pace of Ryan Williamson down the right-hand side was causing the Morton defence all sorts of problems and his cross into the box was met by Joe Cardle, but the East End Park favourite inexplicably fired wide with the goal gaping.

Dunfermline goalkeeper Robinson clashed with Oliver and appeared to kick out, but none of the officials appeared to see exactly what happened.

Home manager Allan Johnston's half-time team talk paid dividends when they drew level just before the hour mark.

As the visitors defence stood back, McManus fired in a shot from the edge of the box that goalkeeper Derek Gaston got a hand to but could not keep out.

Johnston brought on James Craigen, the Pars' new signing from Falkirk, and Kallum Higginbotham, but it was Quitongo, on for debutant Ross, who made the difference with a goal fit to win any game.

The striker collected the ball on the edge of the box and curled a shot beyond Robinson to end Dunfermline's four-match unbeaten run and take Morton into Sunday afternoon's fifth-round draw.

Post-match reaction

Dunfermline Athletic manager Allan Johnston: "I think, on the balance of play, we probably deserved a replay.

"We had the better chances and we are frustrated.

"Obviously they were poor goals we lost today, but we scored a really good goal and probably should have got more from the game.

"Morton, credit to them. They defended really well.

"In the first half, Joe Cardle has got a great chance, but the fortune was on their side today."

Greenock Morton manager Jim Duffy: "It was a very competitive cup-tie that you would expect from two teams in the same division.

"Whether we deserved it or not, I'm no really too worried. We are in the hat and that's the most important thing.

"I thought both goals were outstanding and we also had a couple of great saves from Derek Gaston.

"I thought it was a terrific cup tie and credit to the players for getting us through."
