Hong Kong’s team of Andy Lee and Ka Wei Cheung had assumed a surprise 2-0 lead after the opening singles frames. However, Northern Ireland kept themselves in it by taking the doubles, before a break of 68 from Allen forced a decider. Brown held his nerve to secure the win.
With group table standings being determined by the number of frames won, that result puts Northern Ireland into first position, after they defeated Saudi Arabia 4-1 in the opening round of games. Hong Kong remain in contention, having narrowly lost out to England 3-2 in their first match.
Brown said: “That was just typical Northern Ireland style. We all get behind each other, no matter what tournament we are in. It was pure grit and determination. It wasn’t pretty by any means, but it doesn’t need to be.”
Allen added: “We did really well in the end considering the fact we made a lot of mistakes to go 2-0 down. It was looking bleak but we dug in and I’m proud of Jordan to get us over the line in the end. He played the perfect frame really.”
Saudi Arabia made history by winning their first ever World Cup match with a hard fought 3-2 victory over Iran.
