Portadown turned the tables on a 12-shot deficit to rescue the Irish Junior Cup campaign with defeat of Comber by 81-75.
Comber held control at key moments in the tie, with a lead of eight by 16 ends.
However, Portadown’s strong finish resulted in a scoring sequence of 21-7 in the town side’s favour towards first-round progress and a forthcoming tie with Lisnagarvey.
Andrew Millar, Wayne Dougan, Greg McCartan and Noel Quinn held a slender 11-10 lead on rink one at 11 ends before a string of scoring wrapped up victory by 24-13.
On rink two, Ken Lamond, Joel Hyde, Nixon Armstrong and Noel Orr hit seven ends with a deficit of 18-0.
The Portadown response featured wins across eight ends, including the final five, to restrict Comber’s margin to 31-14.
Josh Hyde, Ken Mulholland, Sean McNeice and Robert Cassells proved resolute against an impressive Comber combination that edged home by 19-17 following a gripping tussle.
George Richardson, Eddie Corkin, Bob Robinson and Errol Whitten met an in-form Comber skip who secured shot for his rink across the opening two ends then got second shot on the third with Portadown holding five.
It was 5-1 to Comber at six ends but strong positional play by Richardson and Robinson switched the momentum and led to six successive wins for Portadown.
This sequence included a seven-shot haul towards leads of 15-6 and 22-9 in the 26-12 win.
The club focus will return to league commitments this weekend.
Portadown A host Lisnagarvey tomorrow (Saturday) afternoon at the Pleasure Gardens, with the B players on the road to face North Down.
