Adelaide teenager Luke Saville has won his second junior grand slam title, taking out the Australian Open boys’ final.

Saville, the world’s No.1 junior and top seed, beat unseeded Canadian Filip Peliwo 6-3 5-7 6-4 on Saturday to add to the Wimbledon title he won last year.

He joins Bernard Tomic as a dual grand slam junior champion and is the third local to win the Australian Open boys’ title in six years.

Tomic won the title in 2008 and followed that with the US Open junior championship the following year, while Brydan Klein took out the Australian Open boys in 2007.

Saville, who turns 18 next week, is the only local to win a title at the Australian Open this year.
