Prompt Response has been agonisingly close to a stakes win a number of times and her co-trainer Adrian Bott is hoping the Twilight Glow Stakes is the race where the filly will finally break through.

The three-year-old has been runner-up in four stakes races during her eight career starts, including her past two starts in Melbourne in the Listed Crockett Stakes at Moonee Valley and then the Listed Lexus Hybrid Plate at Flemington.

She is the favourite for Saturday's Listed Twilight Glow Stakes (1400m) for fillies at Sandown and has drawn barrier two.

"She's shown from day one she's been a stakes quality filly," Bott, who trains in partnership with Gai Waterhouse, said.

"Through a bit of bad luck she hasn't been able to break through just yet but we'll remain confident she will. Hopefully that's tomorrow because she certainly deserves to have a stakes win next to her name because she's been so consistent and so honest and so tough.

"I'm sure her time will come."

Prompt Response, whose only win has been a dominant victory in a maiden at Newcastle at the end of her juvenile season, stepped to 1400m for the first time last start and after drawing wide had to do a bit of work and cover ground to the home turn.

She hit the front in the straight before the talented Jennifer Lynn came with a strong run down the outside from last to deny her by a short-half head.

"She's quite far into her campaign now so she's fit and well and she came through that race at Flemington in great order," Bott said.

"She's proven at 1400 metres which is an ideal trip for her and she's drawn favourably so hopefully she can have a bit of luck this time and can break through because she's been well and truly knocking on the door. And she's certainly good enough."

The stable also has Sweet Redemption and Kimberley Star in Saturday's Group Three Summoned Stakes (1500m) for mares, with last-start Sydney winner Sweet Redemption scratched from a race at Moonee Valley on Friday night to chase a black-type win at Sandown.
