Silk Sari will be making no more appearances in her traditional colours with trainer Luca Cumani reporting Saturday's Qipco British Champions Fillies & Mares Stakes at Ascot will be her last race.

Cumani and his wife Sara bred the daughter of Dalakhani at their Fittocks Stud and ran her in their silks, but required a cash injection to supplement her for this weekend's Group One and have decided to lease her to Michael Watt for the day.

It is not until Silk Sari's four-year-old season that she has begun to show her best, landing a Listed race at Newbury in August but really earning her chance for a shot at such a prestigious event when landing the Park Hill Stakes at Doncaster by five lengths.

"There's nothing else for her (afterwards), she's not doing a Treve. She needs to make babies for the stud," the trainer said.

Silk Sari is disputing favouritism for the race, and looked full of beans when led around Bedford House Stables in Newmarket on Tuesday.

Cumani said: "When I talk to the lads in the morning, I always ask 'well, weller or wellest?' At the moment she's between weller and wellest. We've got three days to get her to wellest."
