But Baek responded with three strikes of his own with just 9 pins separating the duo. Disaster struck the Malaysian as he stumbled to a split in the final frame and but his opponent still needed to strike in the final frame to deny Ang the victory.
But luck was on Ang's side as Baek delivered a seemingly perfect shot only to see stubborn pin 10 standing to the despair of the Korean and losing the tie and the title to the deserving Malaysian, 267-268.
The champion, who averaged a whopping 281 in four matches, ousted local hopeful, Lee Tak Man of Macau, 278-232 in the semi-final to make the finals. Ang also rolled the first-ever 300 in the new scoring format of the ABF Tour which began last year when he beat India's Dhruv Sarda, 300-268 in Round 2.
Ang edged Thailand's Atchariya Cheng in another high-scoring Round 1 encounter, 278-266 to kick start his campaign.
Mr Chao Kuok Wai, Head of Sports Development Department, Sports Bureau of Macao S.A.R. Government presented the trophy and prizes to the men's division while Ms Vivien Lau, ABF Tour Committee Chairman and WOrld Bowling Secretary General gave away the prizes and trophy to the women's division.
