Staying in the second place till his fifth attempt, Sundar on Sunday hurled the javelin to a distance of 61.22 metres in his sixth attempt, enough to jump to the top of the results table tumbling Sri Lanka's Dinesh P. Herath Mudiyanselage who led throughout with his 60.59 metre throw in the first attempt.
It was in fact a double delight for India as Ajeet Singh managed 59.46 metres to settle for the bronze. Compatriot Rinku Rinku took the fourth place with a throw of 57.59 metres. Thus, India secured three more slots for Tokyo 2020 Paralympics.
Earlier, Sandeep Chaudhary and Sumit Antil had secured the quota for next year's Paralympics Games by finishing at the top two spots in the Javelin F64 finals in the ongoing tournament.
India now have two golds, one silver and a bronze so far in the tournament.
