Young striker Lalremsiami (in 20th minute) and Navneet Kaur (in 40th minute) scored for India, while Shin Hyejeong (in 48th min) found the net for Korea.
High on confidence after their impressive outings in Spain and Malaysia earlier this year, India made a strong start against the hosts.
After missing out on an opportunity to score from a penalty corner early in the first quarter, India scored a splendid field goal through Lalremsiami in the 20th minute.
The visitors’ second goal came in the 40th minute when Navneet struck beautifully to extend the lead. It was India’s experienced goalkeeper Savita who made commendable saves to keep her team’s lead intact. India will play their second match of the tour on Wednesday.
