Lady Pimpernel sprung a 20/1 surprise in the feature Upavon Fillies' Stakes at Salisbury, completing a double for Henry Candy.
The four-year-old belied her odds with a dominant front-running display under Dane O'Neill, despite coming into the contest with something to find on the formbook being rated only 89 after winning a Newmarket handicap earlier in the month.
Sent straight to the lead as soon as the gates opened, her rivals couldn't get near the daughter of Sir Percy and she recorded her fourth career success by two-and-a-quarter lengths.
Runner-up Gifted Girl, meanwhile, was in all sorts of trouble attempting to get up the inside and while she eventually found daylight, she could not bridge the gap.
"She's not bad for a seven grand breeze-up horse,'' said Candy, who part-owns the winner himself and is already eyeing a decent profit when he sells her on as a breeding prospect.
"She has the most amazing stride on her, she covers so much ground.
"I'd be in no rush to run her again, maybe once more if she begs for it, otherwise I'd have thought the December sales would be the next call.''
O'Neill told Racing UK: "She's a better filly when she's up front, she just does enough and she's an ideal front-running ride. She's nothing if not resolute and genuine, but she's improved and it's nice to get her some black type."
