James Given's Jadanna puts her unbeaten record on the line in Wednesday's Queen Mary Stakes.
Wins at Pontefract and Beverley have seen her sneak under the radar, but Given feels she may have been underrated going into the Group Two contest.
Winners of Beverley's Hilary Needler Trophy have traditionally performed well in the race, but Given is of the opinion her performance has been downgraded because the runner-up was sent off at 100-1.
"I was very pleased she backed up what she showed at Pontefract in the Hilary Needler, but her success does not seem to have been rated very highly," said Given.
"All she could do was beat what was put in front of her and she also had a little problem in between races so she wouldn't have been 100% at Beverley.
"She also had to start racing very early and the two horses that took her on ended up well beaten and another couple came at her late.
"People have rated her off the second who was 100-1, but we'll find out tomorrow how good she is.
"The shame is that it's such a big field and without being disrespectful, there are some in there who don't look up to the class.
"Unfortunately, because of the weather, there has been a lack of opportunities to run two-year-olds this year so whereas some may have had their bubble burst in previous years, this year that is not the case.
"I think she will get further in time but she's in the Super Sprint. Were she to win, we'd be looking at the Lowther route."
Richard Hannon is always to be feared in the juvenile races at the Royal meeting and won this last year with Best Terms.
This year he runs Jubilee Diamond, the choice of Richard Hughes, Hairy Rocket and Miss Diva.
"Hughesie had a difficult choice to make between our three fillies here, but he has gone for Jubilee Diamond, who bumped into what looked a good one in Upward Spiral (who reopposes) on her debut at Sandown," said Hannon on www.richardhannonracing.tv.
"We have a length and a half to find with the winner, but they pulled five lengths clear of the rest so are obviously two smart fillies.
"Hairy Rocket beat Miss Diva five lengths at Windsor, but the second hated the soft ground that night and went back a week later and won really well on much better going, while you can forget Hairy Rocket's defeat by Graphic Guest in a three-horse race back at Windsor as she got into a suicidal duel early on with Kieren Fallon and Just Past Andover and paid the penalty.
"Ours are all drawn middle to high, so I hope we are in the right place."
Michael Bell's Hoyam arrives as a maiden but is highly regarded at home.
"She's a smart filly and there doesn't look to be anything dominating that position (top two-year-old filly) at the moment," said Bell.
"She's a big, powerful filly and she'll certainly look the part in the paddock.
"I like her a lot and I expect her to run very well."
