Afshan, who was twice runner-up in 2019 and once before that in 2018 and has not won since the 13th Leg of the 2018 season, was on top of the leaderboard after a very long time.
Three players, amateur Vidhatri Urs, Sneha Singh and Ishvari Prasanna carded 1-under 71 each, while two other players, Nayanika Sanga and Shweta Mansingh scored even par 72 each to be tied sixth
Seher, who started the day one shot behind Pranavi, caught up with the leader at the turn. Pranavi, playing with Seher, birdied the sixth, as did the latter.
The 19-year-old Pranavi, a three-time winner this season, led by two over Seher Atwal, who showed a welcome return to form with 1-under 68 at the Par-69 course.
