The Delhi-born Bhambri won the singles title for boys at the Australian Open by defeating Alexandros-Ferdinandos Georgoudas of Germany in straight sets 6-3, 6-1.
The junior Grand Slam victory comes after a gap of 18 years for India. Leander Paes had last win, US Open juniors singles title, in 1991.
A year ago he had won the Wimbledon's singles title. Much before him Ramesh Krishnan had won junior championships at French open and Wimbledon.
But this is the first occasion, an Indian has won the Australian open juniors tournament. The 1992-born Yuki is the brother of sisters, Ankita and Sanaa Bhambri, who also play tennis for India. Yuki Bhambri was the top seeded player in the tournament in the juniors category and is ranked number 2 in the world among junior tennis players.
The victory augurs well for Indian tennis, as it comes close on the heels of Sania Mirza, rediscovering her touch, along with Mahesh Bhupathi, and the emergence of young Somdev Devvarman on the tennis firmament of the country.
