Australian top seed Luke Saville is two wins away from successfully defending his junior Wimbledon crown.

Saville, the world’s top-ranked under-18s player, advanced to the last four when his injured Serbian opponent Nikola Milojevic was trailing 7-5 5-4 in their quarter-final on Thursday.

Bidding to become the first Australian since the great John Newcombe in 1962 to defend his junior title at the All England Club, Saville could face countryman Nick Kyrgios in the last four.

Kyrgios was to play Italian third seed Gianluigi Quinzi in his quarter-final later on Thursday.

Newcombe had a front-row seat for Saville’s quarter-final and would have been impressed after the teenager fought back from a service break down in the second set to stretch his Wimbledon winning streak to 10 matches.

Saville is also the reigning Australian Open boys’ champion and is looking to go one better than Pat Cash and Bernard Tomic as a triple junior grand slam champion.
