Estimate: 'Every chance she will go forwards'
The Queen's runner Estimate will attempt to return to winning ways when she lines up for the DFS Park Hill Stakes at Doncaster on Thursday.
Her Majesty's colours were carried into second place by Set To Music in this Group Two contest over the full St Leger course 12 months ago and the royal runner has a chance of going one better.
The three-year-old filly, trained by Sir Michael Stoute, proved she appreciates a test of stamina when winning the Queen's Vase at Royal Ascot.
However, she was beaten in third place in the Lillie Langtry Stakes at Glorious Goodwood behind Wild Coco and the pair will renew rivalry on Town Moor.
"With three-year-old fillies that mature like Estimate has been doing, you are always hopeful that there is a few pounds of improvement in them as they progress to each race," said The Queen's bloodstock and racing advisor John Warren.
"She is bred to improve and fillies like her tend to do so at this time of year, so I would say there is every chance she will go forwards as opposed to backwards."
Hazel Lavery was only ninth in that Goodwood race, but trainer Charlie Hills reported his filly to be unsuited by the course.
He is expecting a better show from his charge, who had romped home in a Listed race at Newmarket on her previous start.
"She got too far out of the race at Goodwood and didn't really handle the track, so we are hoping for a better showing here," the Lambourn handler told www.charliehills.com.
Ambivalent was only third behind Hazel Lavery at Newmarket but has since defeated Set To Music in a Listed race at Newbury.
Connections of the Roger Varian-trained three-year-old expect her to put up a decent display.
"Ambivalent is in top form so we are hopeful," said Bruce Raymond, racing manager to Ambivalent's owner Abdullah Saeed Belhab.
"She is an improving filly and it's a big step up for her, but we think she is improving enough to put up a good show.
"She won nicely at Newbury last time. She is improving all the time and she enjoyed the faster ground because she didn't like it soft at Newmarket the time before that. We are confident she will stay the trip."Cracking Lass was fourth in the race last year and her trainer Richard Fahey is hoping she can acquit herself well again.
The five-year-old mare returned from an 11-month absence to finish an encouraging fourth to Pale Mimosa in the Galtres Stakes at York three weeks ago.
"It's a tougher race this time. She goes there fresh and well and if she's placed I'd be delighted," said the North Yorkshire trainer.
"We were pleased with her first run back at York, so we'll see how she gets on tomorrow."
