Ciaran O’Sullivan (far left) and Colin O’Reilly combined to hit five consecutive three-pointers without reply in the third quarter as the home side overturned a 12-point deficit.
Michael Goj and Juan Torres helped Swords lead 30-20 after 10 minutes.
Demons regained parity within five minutes of the second quarter and Kyle Hosford found a route to the basket to give them a lead they’d never relinquish.
A 46-38 half-time scoreline allowed them to tee up the shooting masterclass after the break.
Ciaran O’Sullivan spoke afterward about what it’s like to be in the zone.
“You get there a couple of times a year if you’re lucky,” said the Corkman. “Tonight I felt like anything I threw up was going to go in.”
