Badly in need of the experience but shaped quite nicely when third of eight at Southwell three weeks ago (5f); should improve but others bring more pressing claims.

January foal; 140,000gns yearling; first foal of a Group-placed 5f 2yo winner (RPR 92), herself closely related to 6f 2yo Group 3 winner Queen Of Bermuda; stable, who also run Harlequin Sky, having first 2yo runners of the year; a newcomer of note.

SR 52 is modest for this company — needs everything to go right at .

February foal; 20,000gns breeze-up 2yo; ninth foal; half-sister to six winners including In The Breeze (1m2f/1m4f; RPR 91), He's A Rock Star (French 7f-1m5f including 2yo) and Allfredandnobell (2m-2m6f hurdle); dam unraced half-sister to 1m2f Group 1/Grade 1 winner Storming Home; one of two newcomers for Jane Chapple-Hyam.

SR 52 suggests ability but reflects a stiff ask in this field.

Only fifth of eight on her Newmarket debut last month (5f, good) but she was notably strong in the market that day (6-5 favourite) and the race looks a solid piece of form; surprising if she couldn't leave that well behind her in time.

SR 62 suggests ability but reflects a stiff ask in this field.

Lacked the professionalism, as much as the pace, of the three who beat her at Newmarket 17 days ago (5f, good to firm) but it was an encouraging debut with her greenness in mind; open to plenty of improvement; strong claims if coping with the slower ground.

SR 82 suggests ability but reflects a stiff ask in this field.

Dropped right away to finish last of the eight runners on her Wolverhampton debut six weeks ago (5f; 22-1 into 14-1); needs to leave that well behind and probably a longer-term prospect.
