Saturday's 1200m-sprint at Randwick is expected to boast a stellar line-up with Trapeze Artist the equal favourite with Osborne Bulls before acceptances.
Widden Stud will stand Trapeze Artist on behalf of Bert Vieira with the All Aged Stakes on April 20 slated to be his final race unless his owner decides to give him a chance at Royal Ascot.
Vieira delayed Trapeze Artist's stud career at the end of his three-year-old year in favour of a start in The Everest in October in which he finished a gallant second to Redzel.
He has won four Group One races, his most recent the Canterbury Stakes (1300m) on March 9.
Ryan elected to give the four-year-old a barrier trial on Friday rather than race him again before the TJ Smith and Trapeze Artist duly won his heat in a pleasing effort without his race-day blinkers.
“He hasn't missed a beat since the trial,” Ryan said.
“He's got better this preparation and is bright and happy in himself and is ready for the TJ.”
Trapeze Artist led from barrier six of seven in the Canterbury Stakes but Ryan said with a bigger TJ Smith field that scenario was unlikely although he should still be forward in the run depending on his draw.
“I just don't want him to draw the inside,” he said. “Anywhere outside three would be best.”
With four Group One wins already, Trapeze Artist is the most successful son of champion sire Snitzel who Ryan trained to win the 2006 Oakleigh Plate.
The trainer wanted to give Cardiff a trial on Friday and was disappointed he was balloted out with preference given to Randwick-trained horses over Rosehill.
“He's trained on well but I wanted to trial him and I was upset he was balloted out because some of the two-year-old trials only had six or seven runners,” he said.
“There were trials on at Warwick Farm today (Monday) but that's too close to the race.”
