Chris Waller is keeping his options open for the remainder of Unforgotten’s spring campaign after she runs in the Gr. 1 Caulfield Stakes.

The Waller-trained D’Argento and Unforgotten filled the minor placings in the Gr. 1 Epsom Handicap at Randwick behind Godolphin’s Hartnell on September 29 and the stablemates will clash again in tomorrow’s 2000-metre weight-for-age Caulfield feature. Unforgotten’s performance will dictate her immediate programme.

“Her run on Saturday will determine where she goes next, and there is an outside chance she could go to the Caulfield Cup a week later,” Waller said. “She will probably head to either the Cox Plate if she wins, or the Myer if I thought she was looking for something easier to finish off the preparation.”

A tilt at the Cox Plate would mean a clash with her champion stablemate Winx, who is the short-priced favourite to win the prestigious weight-for-age race at Moonee Valley for an unprecedented fourth time. The Myer Classic at Flemington for fillies and mares is on November 3, a week after the Cox Plate.

Winner of the Australian Oaks in April, Unforgotten was at $13 on the TAB’s Caulfield Cup market today, with her stablemate Youngstar the favourite at $5. Waller said he could not be happier with how Unforgotten had come through her third placing in the Epsom.

“She is a very good horse but she is obviously racing against some seasoned weight for age campaigners here,” he said. “However I feel she will certainly be in the finish.”

The star-studded Caulfield Stakes field has a significant international presence but the Waller-trained pair head the market with D’Argento, who has the outside barrier, the $4.80 favourite just ahead of Unforgotten at $5. D’Argento won the Rosehill Guineas over 2000 metres in the autumn.

“He is ready for the 2000 metres and went to Caulfield on Tuesday morning and got around the track without any issues, so he just needs an ounce of luck and he will show his class,” Waller added.
