American Sebastian Korda has claimed a unique place in sporting history with victory in the Australian Open junior boys’ final on Rad Laver Arena.

Korda beat Taiwan’s Chun Hsin Tseng 7-6 (8-6) 6-4 in Saturday’s final – 20 years after his father Petr won the men’s championship on the very same court at Melbourne Park.

In an incredible sporting treble unlikely to be repeated, Korda’s 24-year-old sister Jessica also won the 2012 Australian Open women’s golf championship at Royal Melbourne.

Korda’s victory denied Taiwan a rare double after En Shuo Liang earlier defeated France’s Clara Burel 6-3 6-4 in the Australian Open junior girls’ singles final on Margaret Court Arena.
