Ballyclare Comrades 0 Larne 1
Dean Jarvis praised Larne's mentality after he struck the extra-time blow that took them past Ballyclare Comrades.
After big wins in the Danske Bank Premiership over Glentoran and Linfield, it was a less than clinical display from Tiernan Lynch's side against the resilient Comrades, but Jarvis was proud of their battling qualities to secure the win.
"We knew before the game it was going to be a tough, tough game," said the new recruit.
"It was a boggy pitch and we knew we wouldn't be able to play the game we normally play on our 3G pitch.
"We just had to battle through. We were disappointed to go to extra time, we thought we had enough chances to win it within the 90 minutes, but we're in the hat for the next round and that's all that matters."
Ballyclare chief Paul Harbinson was disappointed to see his side's efforts undone from a set piece.
"For us to defend so well all day, and then be beaten by a ball coming into the box and finding a free man, that's tough," he said.
"But the overwhelming emotion is pride. The boys worked so hard."
