Holders Cliftonville came from two goals down to continue their defence of the BetMcLean Cup, and will be joined in the semi-finals by last season's runners-up Coleraine plus Glentoran and Linfield.
The Reds welcomed Newry City to Solitude and trailed at the break through goals from Brian Healy (from the halfway line!) and Donal Scullion.
However, a Joe Gormley quick fire double just before the hour brought Paddy McLaughlin's side right back into the game before Ronan Hale took the ball past a couple of defenders to bag the winner with just over ten minutes remaining.
Cliftonville will face Coleraine in the semi-finals after the Bannsiders hit three goals without reply past Dungannon Swifts at The Showgrounds.
Michael McCrudden and Matthew Shevlin found the net within a few minutes of each other midway through the first half, with Evan McLaughlin adding a third in stoppage time.
Linfield also swept to a three-goal victory as they accounted for Championship opponents Annagh United at Windsor Park.
Joel Cooper opened the scoring on 25 minutes but that was how it stayed until the closing stages when Cooper struck again before teenager Liam McStravick, on his debut, knocked home a third right at the end.
The Blues go into a semi-final with Glentoran after Mick McDermott's side got past Championship leaders Loughgall at Lakeview Park.
Scoreless at the break, Terry Devlin fired home a superb finish high into the net on 54 minutes with Bobby Burns doubling Glentoran's lead soon after from close range.
