Chris Waller admits he may have got a bit carried away in the spring when he labelled Catkins the next Red Tracer.

But the mare came within a short half head of toppling her stablemate at Group One level in the Myer Classic and that performance has the trainer excited about her autumn prospects.

Waller's problem is to keep the two apart as much as he can with Catkins to begin her campaign in Saturday's Group Two Breeders' Classic (1200m) at Rosehill and Red Tracer to make her return a week later.

"She isn't fully wound up yet but she has come back well," Waller said.

"I might have been a bit excited when I called her the next Red Tracer but she has built up an imposing record and has a high winning strike rate.

"She is a nice strong horse and the type who can overcome difficulties in a race.

"I hope she can get to the Coolmore. Red Tracer will probably be weighted out of that race so it looks ideal for Catkins.

"I want to keep the two mares apart as much as possible so Red Tracer will come back in either the Triscay the week after or the Millie Fox another week later."

The winner of eight of her 17 starts, Catkins is the second favourite for the Breeders' in first markets with the unbeaten White Sage holding sway.

The John O'Shea-trained White Sage claimed her first black type win in the Listed Festival Stakes in November at her fifth start.

Triple Group One winner Streama is the third elect in Saturday's race for mares' which has attracted eight runners.

Streama is also on a collision course throughout the autumn with her Guy Walter-trained stablemate Appearance, winner of last Saturday's Expressway Stakes.

Blake Shinn, who won the George Main Stakes on Streama last October retains the ride.

Steps In Time, prepared by O'Shea to win the past two Breeders' Classics, will have her first start for new trainer Joe Pride.

With O'Shea to take over at Darley at the beginning of May, the owners of Steps In Time transferred her to Pride for a campaign which they hope extends to the Brisbane winter carnival.
