This filly made her debut last September when third in a Newmarket maiden behind Qabala, who this week catapulted into 1,000 Guineas consideration when winning the Nell Gwyn Stakes.
It is perhaps no surprise that Rainbow Heart should subsequently frank the form in trotting up by eight lengths at the same venue three weeks later.
The well beaten runner-up, Pytilia, won nicely at Lingfield the other day, further advertising the form.
SENZA LIMITI (nb, 3.10) can provide another success for Haggas and his jockey Oisin Murphy.
A lot was expected of this 100,000 guineas purchase and he did not disappoint when winning a novice event at Salisbury last October very comfortably.
He carries the green colours of Simon Munir and Isaac Souede which are much more familiar to jumping fans through the likes of Bristol De Mai and Sceau Royal.
The Queen’s Prize at Kempton is not the race it was in the racing calendar 20 and more years ago but that will not worry the connections of CAYIRLI (treble, 4.50).
This seven-year-old picked up a course and distance win in early February and the 3lb he has been put up by the assessor may not be enough to stop him.
