In the big contest of the night, South Korea came back from 0-9 down to lead at half time against Bangladesh and that scenario repeated itself in the second half too. Bangladesh retained their lead in the second half before Jang Kun Lee turned the game upside down with a Super Raid and then a touch to flip things from 28-31.
The win means Korea remain unbeaten in the Pool A standings and jump over India with three wins in three matches to post 15 points.
Elsewhere, Thailand made little of Kenya in the first game of the night in Ahmedabad. Khomsan Thongkham and Khunakon Chanjaroen stood out for the Thais with 14 and 10 points respectively to win by 53-21. Kenya faltered with poor raiding and many of their attempts were empty.
