The Newmarket handler has earmarked the Group Three prize as starting point for the daughter of Frankel, after ruling her out of the Listed Oaks Trial at Lingfield on Saturday on account of the soft ground.
He said: “She is going to York. I just bottled out of it because of the ground and I didn’t want her to have to hard a race. It was not as soft as I thought, but there was some rain forecast and I had to make a decision in the morning.
“She will run on Wednesday anyway.”
Haggas has yet to decide whether to run stablemate Rainbow Heart in the Musidora or wait for the Listed Oak Farm Stables’ Fillies’ Stakes at the Knavesmire on Friday.
He said: “Rainbow Heart is also in the mile Listed race on Friday, so I don’t know if she will run in the Musidora. I’ve got a bit of sorting out to do.”
