There will be little rest for Harlem Lady, which will back up at Randwick after ending a sequence of minor placings with victory at Rosehill.

The Chris Waller-trained mare races in the same colours as Winx but unlike her champion stablemate had been placed at her previous four starts leading into Saturday's Benchmark 85 (1500m).

Brenton Avdulla timed his run to perfection on Harlem Lady ($4.80) and brought her down the outside to beat Frill Seeking ($11) by a length.

"The plan was to back her up over 1800 metres at Randwick next Saturday and we will stick to that," Waller said.

"It's a good time to try her over the distance. She is a Zabeel mare and that will help.

"Her rating will go up and she will have to carry 61 kilos. She is not an apprentice's horse so she will have to carry the full weight but there's nothing else for her so we'll give it a go."

Sydney's premier trainer said although Harlem Lady's run of placings might look frustrating, it was anything but.

"She is consistent," he said.

"I thought she was going to run another placing but she is always running well.

"It's good to see her win but it's also good when she runs places."
