Meanwhile, the action in the 14/u Australian Championships continued on the weekend, and there was a big upset, with No.2 seed Dayne Sweeny eliminated in the second round of the boys’ draw.

There was no such trouble for top seed Tristan Schoolkate, who has dropped just seven games in three matches en route to the quarterfinals.

Third seed Ken Cavrak and No.4 seed Nikita Volonski are still alive in the tournament and will contest their third-round matches on Monday.

Marshall has been particularly impressive, dropping a meagre three games in three matches to reach the last eight.

No.2 seed Madison Bishop is through to the third round and on Monday will look to join Marshall and Gadecki in the quarters.
