Borgohain clocked 20.75 seconds to win the men’s 200m final and set a new meet record.

Manju Bala Singh, a 2014 Asian Games medallist, had five throws over the 60m mark with a career best of 64.42m on her third attempt to claim the women’s hammer throw meet record from Hardeep Kaur who set it at 61.67m in 2002. Sarita Romit Singh came up with a 59.58m effort on her last try to edge Railways' teammate Jyoti Jakhar Rana to third place.

Sanjivani Jadhav, who was second in the 5000m, emerged on top with a comfortable win in the 25-lapper.
