Tamreer produced a major upset with a determined success in the Sky Bet Handicap at York.
Roger Fell’s four-year-old had been third in a Listed race on her penultimate start, but failed to fire at Doncaster last time out and was sent off a 33-1 chance for the mile-and-a-half contest.
Positioned just off the pace by jockey Ben Curtis, Tamreer made smooth headway two furlongs out and stayed on stoutly to deny Corelli by a neck.
Favourite Caradoc was a further neck back in third, while Gibbs Hill made eyecatching late progress to finish fourth.
“I didn’t think she had a cat in hell’s chance, which shows you what I know!” Fell said.
“It’s great to have a winner here – I can’t believe it. A winner at the Ebor meeting is different class.
“I expected the jockey to come back in and say she wasn’t fit, but she’s obviously got fitter for putting weight on and she looks a lot stronger.”
The North Yorkshire-based handler is keeping options open for the daughter of New Approach and she could be pitched into higher company on her next start.
“She’s got black type and the only way it could get better is by winning a Listed race,” he added.
“That would give her really good value, so we’ll see what we can find.”
