LUCKNOW, Aug. 26 -- The AITA Championship Series Under-16 at the SDS Tennis Academy on Tuesday produced a day of dominant displays and surprising upsets as Uttar Pradesh talent stamped its authority across both the boys' and girls' draws. The pre-quarter action served notice that this year's event will be fiercely competitive, with top seeds tested and several unseeded challengers announcing themselves in style. In the boys' section, top seed Arjun Sharma set a ruthless tone, dismantling Shaurya Singh 6-0, 6-1 in a clinical performance that left little doubt about his ambitions. But the day belonged to several upset-makers who refused to follow the expected script. Seventh seed Tejas survived a scare and a dramatic super tiebreak to outlast Yaduraj Bhinai of Rajasthan 5-7, 6-1, 10-7, showcasing resilience under pressure. Third seed Rohin Raj advanced with a steady 6-4, 6-3 win over Ashwin Chauhan of Uttarakhand, while Saatvik produced a notable result, defeating fifth seed Arnav Chauhan 6-2, 6-4 to underline his growing confidence. Local boy Dhruv continued the home-state momentum with a commanding 6-0, 6-2 victory over Samarth, and fourth seed Virat booked his place in the quarters with a composed 6-2, 6-4 win against Mohammad Sufiyan. The biggest shock in the boys' draw came when Abeer Ranjan of Bihar upset eighth seed Pavith 6-2, 6-4 - a scalpel-precise performance from the unseeded hopeful that disrupted the seeding expectations. Rounding out the surprises, Haris Khan delivered a statement, toppling second seed Rishant Jaiswal 6-2, 6-2 in a confident display of aggressive baseline tennis.
