An impressive first half performance by Dalriada ensured victory in their Schools Cup match at Carrickfergus.
They built up a 15 points advantage over the home side, which could have been even more as they dominated possession.
Ulster Schools outhalf Andrew McIlroy responded with a converted try in the second half but Carrick did not get closer.
Dalriada’s reward is the difficult task of a trip to Foyle/Londonderry College in the next round.
No.8 forward Michael Allen scored the first try after a forward drive before Lee Ballentine kicked a penalty.
Dalriada then added a Roger Bonnar try which Ballentine converted to put the visitors in control.
With so little ball, the fleet-footed home three-quarters were unable to show their capabilities until the balance of play changed in the second half.
A much improved Carrick performance saw them create opportunities and they were encamped around the '22' for long periods.
But the stout visiting defence held until the final 10 minutes when McIlroy showed what he is capable. He found a gap in the defence and cut through for a try which he also converted.
It was too late for a comeback but at least they had proved much sterner opposition than they did in an early season friendly and the second half display pleased Carrick coach Neal Kennedy.
“We were pressurising frequently but were just unable to break through and a score early on would have generated extra confidence which could have seen us through to success,” he said.
