Price is shorter than the model makes it.
Disappointing in similar event over C&D when last seen and is 0-5 since winning the Lowther as a 2yo; however, this seasonal debut may be the time to catch her; good third to Sayidah Dariyan in Group 3 at York (6f) on 2025 reappearance.
Group 3 winner in July 2024; campaigned mostly at Group 1 level since, making the frame on several occasions, most recently in the 2025 Sprint Cup at Haydock (6f, good) where she did well having met trouble; leading player back down in class.
Novice winner as a 2yo; placed four times in Listed grade, most recently runner-up over C&D (good to firm) on final start in 2025; ran below market expectations at Bath on reappearance but consistent on the whole and may rebound.
Ended last season in a consistent vein of form at Listed level, creditable third at Doncaster (6f) the final time; may continue to give her running but that won't be enough to belatedly double her tally; 0-9 since 2yo debut success.
Gained her French wins in maiden/handicap races; faded late over 7f on the AW finals card at Newcastle on British debut; may prove suited by this drop back in distance but the opposite is true of the step back up in class; stiff task.
Low-mileage filly whose form wearing hood comprises a success in 6f novice event and two good efforts in Listed grade, third at Ayr when last seen (final outing for Mark Usher; remains with same owner); could go well in the retained headgear.
Record is 5-13; ended her 2025 campaign with an August double that comprised a Listed race at Pontefract (good to firm) and Group 3 at Deauville (soft), both over 6f; progressive and tactically versatile mare who warrants respect on reappearance.
Had excuses (trip/draw) returned to Group 1 level in last two appearances; progressive otherwise and ran well in the Commonwealth Cup prior to Group 3 win at York (6f, good) last summer; may still have more to offer; major contender.
Has come up short in Group 1 attempts, including last two appearances; record when racing below that level on turf is unblemished (5-5) and features Listed, Group 3 and Group 2 wins on British, French and Irish soil; strong claims back down in grade.
