There are just 64 teams left vying for fonaCAB Junior Cup glory after Saturday's second round ties whittled the field down.
The designated 'tie of the round' saw Northern Amateur 2A side Kelvin Old Boys take on derby rivals from the division below, Taughmonagh YM, at Seaview with the 2B side upsetting the form book by securing a 4-3 win.
The game got off to a storming start when Curtis Farrell fired Kelvin in front on 13 minutes, only for Robbie Hoy to level for Taughmonagh six minutes after that.
Hoy struck again barely three minutes later to edge Taughmonagh into the lead for the first time before Curtis Moorehead to restore parity later in the first half.
Jack Scott then tipped the balance back in Kelvin's favour just after the hour but two late goals from Jay Nicholson and Carter Bacon saw Taughmonagh do enough to book their place in the next round.
Holders Dergview Reserves were pushed all the way by Magheraveely before coming out on top after extra-time.
Stephen Mills had edged the Castlederg side in front after just nine minutes but a Dale Maxlwell own goal levelled matters halfway through the first half.
But another Mills strike early in extra-time, followed swiftly by a Joel Gibson put Dergview back in control and although the home side reduced the arrears through Joseph Willamson it wasn't enough to force the game into penalties.
However, no fewer than nine games did require the dreaded spot-kicks to settle them with Trojans YCG, Belfast United, Irvinestown Wanderers, Antrim Rovers, Limavady RFC, HW Welders U21, Donacloney and Red Star all keeping their collective nerves to progress.
Ardmore clocked up the joint highest win of the round, hitting 11 goals without reply past Caw - made all the more remarkable by a stunning seven-goal haul for Jack Coyle. Balnamore also knocked home 11 goals, with Artigarvan the unfortunate victims.
Lurgan Celtic got amongst the goals with a 9-0 win on the road over Ballymena side Waveney Swifts, including a hat-trick for Jonathan Reynolds with Enniskillen Town United, Enniskillen Rangers and Castlewellan Town enjoying eight goal victories.
Three players hit four goals apiece, namely Mark Roarty (Sion Swifts), Daniel Toal (Belfast Athletic) and Duwayne McManus (Enniskillen Town United) with a further six claiming the match ball with a hat-trick - Chris Kerr (Magherafelt Sky Blues), Jordan Campbell (Clough Rangers), Matthew McMenemy (Killymoon Rangers), Thomas Elder (Balnamore), Rhys Clarke (Castlewellan Town) and Kane Rossiter (Camlough Rovers).
