Suljovic took a quick 4-0 lead after hitting two 12-dart legs and two 15-dart legs. He came one leg away from victory after finishing 65 in the fifth leg. Labanauskas avoided a whitewash as he hit tops in the sixth leg, before the Austrian threw a 14-dart leg to seal the victory.
James Wade also moved into the next round, after a thriller against Peter Wright. 'The Machine' hit 40 percent of his double and averaged nearly 103.
