The series already in it's pocket, Indian women's hockey team lost 0-4 to hosts South Korea in the inconsequential third and final match of the rubber, here Friday.
India had earlier registered back-to-back identical 2-1 wins over Korea in the first two games to pocket the series.
India's defence was put under huge pressure right from the start as the hosts made successful forays into the striking circle.
The hosts created as many as five penalty corners in the match and converted one in the 29th minute.
Jang Heesan opened the scoring for Korea followed by back-to-back goals in the 41st minute from Kim Hyunji and Kang Jina.
The three goals dented India's morale and any chances of a comeback into the match. Lee Yuri's goal in the 53rd minute further sealed the match in favour of the hosts.
