Representing the Nation: The Indian Team Selection
The pinnacle of his young career came in March 2025, when his consistent dominance on the AITA circuit earned him a call-up to the Indian U-14 National Team.
Selection for the national team is the dream of every young athlete. For Kaustubh, this meant representing the 'Tricolour' at the World Junior Tennis Competition (WJT) held in Malaysia in April 2025
In April 2025, Kaustubh traveled to Kuching, Malaysia, as a key member of the Indian U-14 squad. The WJT is essentially the "Junior Davis Cup," where the best talents from the Asia/Oceania region battle for a spot in the World Group.
