But the Hong Kong national recovered with three additional strikes as the Taiwanese failed to roll strikes and just spared his next three frames. Adding a fourth strike in the ninth frame allowed Mak to shut out Hsu to win his second consecutive title in two days.
The champion averaged 253.5 over fourth matches en-route to his victory. He almost rolled the first 300 in the new World Bowling scoring system but missed the head pin in his final shot to beat Chen Wu-Chi of Chinese Taipei 287-233 in the second semi-final match.
Mak edged a second Taiwanese, Wang Chen-Hsiung 243-235 in the second round after winning the opening match, 217-182 against his first Taiwanese opponent, Hsu Yin-Chou.
The runner-up had to beat three fellow-countrymen to reach the finals. He first ousted second-seed, Wu Hao-Ming 222-201 in the first round and then Yeh Meng-Wei, 213-211 in the second round. He had another narrow victory over Chen Ying-Shen, 222-220 in the first semi-final match.
