Navneet Kaur (3rd & 41st minutes), Rani (15th & 18th) and Navjot Kaur (30th & 50th) netted the ball twice, while Lalremsiami (18th), Deep Grace Ekka (25th), Gurjit Kaur (41st) and Sonika (45th) scored once each to ensure India notched up winning points in their opening match of Pool A.
India began with positive intent by attacking Singapore's circle constantly, looking for an opportunity to score.
The effort worked as the team won back-to-back penalty corners in the first quarter. Though the first PC was saved by Singapore goalkeeper Felissa Lai, it hardly dented India's spirit as they were precise in their counter.
India continued their fine run in the second quarter as well, adding four more goals, to go into the 10-minute half- time break with an imposing 6-0 lead.
