I also got to hit with Tommy Hass and play a few sets with Radek Stepanek. I have the confidence that I can win my second junior Slam but I can't take anything for granted.'
Yuki, in January, had become the first Indian to win a junior title at Melbourne Park and fourth to win a junior Grand Slam.
Ramesh Krishnan had won junior Wimbledon and French Open in 1979 while Leander Paes was the last Indian to win a junior Grand Slam when he won the Wimbledon boys' title in 1990 and the US Open in 1991 as a 17-year-old.
The Delhi boy will be looking to join that elite club.
'It is definitely a matter of pride to win two Grand Slams. But I am not thinking about it. The fact that it could be my last junior Grand Slam, though I might play Wimbledon next year, is a motivating factor.'
'But as of now I am focussing on my first match here. If I clear the first couple of rounds, then I should be fine.'
