A Michael O'Hagan goal after half-an-hour was enough to secure a last eight spot in the O'Kane Cup for Second Division strugglers Randalstown Athletic at the expense of top flight opponents All Saints Old Boys.
O'Hagan blasted the ball home after a Willie Fry cross was headed back across goal by Gavin Andrews at the far post.
All Saints might have levelled on 55 minutes but somehow Gareth Gordon failed to beat the keeper despite being played through by Conor Crilly.
At the other end Conor Johnston sent Andrews clear but his effort was turned around the post.
Despite being reduced to ten men with a few minutes remaining, Randalstown held on to earn the right to take on Harryville Homers in the quarter-finals.
The Homers progressed courtesy of a 3-1 away defeat of Ahoghill Thistle in the only all top flight clash of the round.
They opened the scoring on 20 minutes when Keith Wylie picked out Geoff Mitchell down the left who then delivered a low cross into the six yard box for Gary Bonnes to drive home.
Gareth Mott kept his composure to take the ball past the Thistle keeper from an Alan Rainey ball 15 minutes later to double their advantage before killing the game as a contest ten minutes after the break with a weak shot which somehow trickled home.
Thistle did manage a consolation when David Tenant beat the offside trap to race clear and score, but the dismissal of two players late in the game ensured a gripping finale was out of the question.
FC Moylena crept through after a nine-goal thriller against new boys FC Inter Stars.
Cliff Wilson opened the scoring after two minutes with Stuart Burrows doubling their lead ten minutes after that when he slid the ball under the keeper.
However, Sebi Condurache pulled one back for the visitors on the half-hour mark only for Moylena to restore their two-goal cushion on 62 minutes through Peter Warhowski only for Condurache to respond once again for the Third Division leaders.
They then levelled moments from the end of normal time when Florin Bordeiann progressed down the right flank before crossing for Marios Abiculesei to nod home.
The first period of added time ended scoreless, but then goals from Burrows and Wilson sandwiching one from Daniel Abore saw Moylena just about earn the right to take on league champions Carniny Rangers in the last eight.
