Bangalorean Aditi, who has been one of the most promising talents in women's golf in India, had a rough front nine going three-over but she recovered on the backward journey and ended the day at one-over 71 at the Bangalore Golf Club.
Joining her in the lead was Tvesa, who shot steady 35 and 36 on the front and back nines. Both Aditi and Tvesa had two birdies each against three bogeys.
As many as five golfers were bunched at four-over 74. They were Astha Madan, Amandeep Drall, Vrishali Sinha, Ridhima Dilawari and Vidushi Sinha.
Amrita Anand and Gursimar Badwal carded 75 each to complete the top-10.
While the top eight golfers figure in Category A (15-17 years), Amrita Anand led Category B (13-14 years) with Ankita Kedalya (77) second. In Category C (Under 13), the leader was Ananya Barthakur (78) and Anika Verma was one shot behind her.
