In the Ladies' Open division, Amabel Chua of Singapore denied 2017 champion and topseed, Lara Posadas-Wong of Philippines her second victory after the 19-year-old 2019 Asian Youth Team gold medallist, edged the Filipino, 212-190 in the title match.
Posadas-Wong got off to an unlucky start by conceeding a split in the opening frame. But Chua did not take the opportunity to pull away by stringing consecutive strikes in the first four frames. Chua eventually found her line to reel in three strikes-in-a-row from frame 5.
Although Posadas-Wong responded with a double in the sixth and seventh frames, another split in the eighth frame more or less decided the tie in favour of the Singaporean. Chua, who had finished second with 1656, 74 pins behind Posadas-Wong in the earlier Round 2 finals, ousted third-seed, Aldila Indryati of Indonesia, 202-192 to earn a crack at the title.
Chua took home the top prize of 300,000 pesos (approx. US$5,770) as champion leaving Posadas-Wong settling for 150,000 pesos as first runner-up. Indryati picked up 75,000 pesos as second runner-up. Reigning AMF World Cup champion, Krizziah Tabora of Philippines missed the cut for the stepladder finals by four pins finishing fourth.
