Chris Waller is looking to Randwick to dry out before confirming whether Winx makes another appearance in a barrier trial.
But if she doesn't step out on the Kensington track on Tuesday, the trainer is not concerned with the champion mare on target for her return in the Warwick Stakes on August 20.
"She doesn't need another barrier trial," Waller said.
The six-time Group One winner had an easy trial at Randwick last month and with a couple of solid gallops at Rosehill under her belt, she is ready to begin her spring campaign.
The Warwick Stakes meeting will be the first time any of Waller's team will contest a stakes race this season with Sydney's premier trainer without a San Domenico Stakes runner on Saturday.
The Peter and Paul Snowden-trained Tycoon Tara won Saturday's Group Two Missile Stakes and the new partnership of Gai Waterhouse and Adrian Bott took out the other feature, Listed Rosebud.
But Waller will be well represented on San Domenico day at Rosehill.
"Sadler's Lake and Cosmic Cube will run in the Spring Preview," Waller said.
"Cosmic Cube is new to the stable. He came from David Vandyke who has gone to Queensland and he trialled well.
"Marenostro and and Sacred Master run in the 1800 metre race. Sacred Master had the flashing light on last time and the 1800 will suit him better."
Former New Zealander Sacred Master, third in the Auckland Cup, finished eighth in the Listed Winter Challenge (1500m) at his first Australian start, less than three lengths from the winner Marenostro.
Sacred Master is one of 14 horses from the stable entered for the Caulfield Cup in October.
