At the inaugural Northern Ireland Open, King beat Igor Figueiredo, Liang Wenbo, Fergal O'Brien, Kurt Maflin, Hossein Vafaei Ayouri and Kyren Wilson to reach his first ranking event final since 2004. He was 5–1 down to Barry Hawkins, before winning six successive frames. King went on to be 8–7 up, with the 16th frame going to a re-spotted black after King had needed a snooker and he missed a double on it to win. King took the deciding frame to win a ranking event for the first time in his 25-year career. He paid tribute to his father who had lent King money for the trip to Belfast.
