Tropical rain interrupted play twice and although conditions eased sufficiently for organisers to let it resume in the afternoon no one had managed to complete their round when bad light forced them to abandon play at 6.38pm.
2017 SEA Games men’s individual gold medallist Hamamoto was 12 holes into his round at the time, while Settee had played one hole less.
Play will resume at 7am on Saturday and those who make the cut will proceed to round three immediately afterwards.
