British champion Flat jockey Oisin Murphy takes the ride on 1000 Guineas contender Millisle on 7 June.
It is the first time Murphy will ride for trainer Jessica Harrington. Shane Foley partnered the daughter of Starspangledbanner to her big race success in the Group 1 Cheveley Park Stud Stakes on the Rowley Mile.
Millisle has yet to race over further than three-quarters of a mile in five starts as a juvenile. Her trainer is bullish about her Classic claims.
“Shane can’t ride Millisle, so I’ve gone and booked Oisin Murphy good and early for her,” said Harrington. “I’m not slow out of the gates, you know. I’ve been thinking ahead.
“Millisle heads to the 1000 Guineas at Newmarket and I see no reason why she won’t stay a mile. Her breeding suggests she will get it anyway.
“She has done very, very well over the winter and you’d have to be excited about her for the season.”
Analysis: Plenty suggests Millisle will get the trip

Millisle won three times at two, progressing from maiden company to a Group 1 winner. Now comes her biggest test to date.
One of a crop of fillies held in high regard from Harrington’s stable, the betting suggests there are few doubts about her staying.
At a best-price 10/1 with bookmakers, Millisle is a leading contender on the way she finished off the Cheveley Park.
She ran on well in the final furlong on the Rowley Mile beating dual Group 2 scorer Raffle Prize by 1 3/4 lengths.
Tropbeau can advertise that form – and pay a huge compliment to her – by justifying favouritism in the French equivalent on 1 June.
Form students will have their eyes on Deauville then where the Cheveley Park third looks to win a Classic of her own.
Millisle’s new jockey Murphy will be in even higher demand this season when not riding for retained owners Qatar Racing.
