Bohemians 0-0 Sutton United
(Bohs win 4-3 on penalties)
Goalkeeper Shane Supple saved two penalties as Bohemians became the first Irish side to reach the quarter-finals of the Irn Bru Scottish Challenge Cup with a penalty shootout victory win over Sutton United.
Things were looking grim for Keith Long's side after Oscar Brennan and Eoghan Stokes saw successive penalties stopped by Ross Worner after the game remained scoreless after 90 minutes.
That was until Supple intervened, saving the final two penalties of the allotted five, and netting his own, to force sudden death.
Rob Cornwall kept his nerve and, when Aswad Thomas' kick struck the underside of the bar and bounced out, referee Michael Roncone consulted with his officials and awarded the win to Bohs.
It was no less than the home side deserved as they played virtually all of the football throughout – almost to a fault as they gifted the visitors opportunities by playing too much around their own box.
Their patient, possession-based style seemed to surprise Sutton, however, who struggled to get their foot on the ball and should have fallen behind within four minutes.
The electric Dan Kelly cut in from the right and let fly and Worner spilled the tame effort, but Dinny Corcoran couldn't get the contact to put the rebound into an empty net from eight yards.
Kelly was at the heart of the action again moments later as he zipped through the centre before being chopped down by Dale Bennett, who was booked, but Stokes put the free kick into the wall.
Sutton, who boasted League of Ireland experience up top with Cork City product Aaron Drinan and former Sligo Rovers striker Jonah Ayunga, looked to use their physical prowess by going long.
It almost paid off as Bohs struggled to clear Wayne Brown's corner, and Charlie Clough's shot was bundled home by Tom Bolarinwa, but the goal was rightly chalked off for offside.
And a rare error in possession from captain Derek Pender allowed the impressive Ayunga to tee up Craig Eastmond, but the former Arsenal midfielder's shot was easily saved by Shane Supple.
Bohs had another great chance just past the halfway mark in the first half as JJ Lunney's beautiful through-ball picked out Kelly, but the winger poked his shot inches past the far post.
Sutton's discipline continued to worsen through the half and manager Paul Dowell was dismissed following a number of tirades against referee Michael Roncone.
And Bohs felt they should have had a penalty on the stroke of half time as Worner again spilled a Pender cross and Corcoran went down under Clough's challenge, but nothing was given.
Bohs continued to dominate into the second half as the English side looked to tire as they chased the ball, but Bohs lacked the creative spark to break down their stubborn resistance.
The visitors found a second wind and could have led when Clough, who was lucky to stay on the pitch after a two-footed lunge on Kelly, saw his header taken off the line by his own player.
Then a well-struck low effort from Ayunga, who was Sutton's best player throughout, was too hot fr Supple to handle and Bohs were lucky Josh Taylor couldn't turn in the loose ball.
Byrne had a great chance to put Bohs ahead when he found himself free at the back post, but he could only turn Stokes' chipped free kick back at Worner.
The English side peppered the Bohs box with crosses as they finished the stronger, and Clough somehow put a free header wide with nine minutes remaining.
The home side just about managed to hold on but still looked set to lose out until their recent international call-up changed the game in a remarkable 60-second reversal.
