Petrushka proved herself Europe`s top middle-distance filly with a sparkling performance against high-class opposition in the Aston Upthorpe Yorkshire Oaks.
Sir Michael Stoute`s charge was confidently ridden by Johnny Murtagh as last year`s winner Ramruma cut out the early running from Ela Athena - runner-up 12 months ago - and Vodafone Oaks heroine Love Divine.
Love Divine went on three furlongs out but Murtagh had the move covered and the Irishman eased Petrushka to the front approaching the final furlong.
The daughter of Unfuwain comfortably held off Love Divine by one and a quarter lengths with Ramruma two lengths back in third.
Petrushka, the 5-4 favourite, who was following up her impressive victory in the Irish Oaks, will be dropped back to 10 furlongs for her next outing.
Harry Herbert, managing director of owners Highclere Thoroughbred Ltd, said: 'Coming up to this race the favourite was to go next for the Champion Stakes followed by the Breeders` Cup Distaff.
'The Arc was considered but going for these two races instead gives the filly a nice break between races.
'If all the shareholders agree then she could be kept in training for next year when she could be aimed at the Arc.'
Murtagh was delighted with Petrushka`s effort.
He said: 'She was very relaxed today and settled well and travelled well.
'Kieren (Fallon) told me to let her find her feet and go with a furlong and a half to travel and she`s won well.'
Henry Cecil was satisfied with the performances of his two fillies.
He said: 'Both fillies have done me proud. Ramruma has done really well considering she has been off since coming back lame from the Guineas meeting.
'Love Divine loves soft going and couldn`t quicken so well on the ground.'
Murtagh completed a double when 11-1 chance Bannister led home a Richard Hannon one-two in the Scottish Equitable Gimcrack Stakes.
The winner was always in the front-rank but looked beaten when stablemate Zilch (20-1) quickened into a half-length lead inside the distance.
However Murtagh galvanised another run form his partner and he was back in front in the dying strides.
Juniper (9-2) ran a race full of promise in third.
Give The Slip made every yard of the running to take the #175,000 Tote Ebor.
The valuable handicap is traditionally one of the toughest and most-competitive events of the season but the Amanda Perrett-trained three-year-old showed great guts and determination to hold all challengers at bay.
Evergreen jockey Pat Eddery, chasing a remarkable 12th jockeys` championship title, was riding his 100th winner of the season.
The son of Slip Anchor, sent off a well-backed 8-1 chance, kept pulling out more for Eddery to hold 11-4 favourite Boreas by three-quarters of a length with Virgin Soldier (14-1) a head back in third. Afterjacko (20-1) was fourth.
Perrett, whose father Guy Harwood won the race with Crazy and Primary, said: 'I`m so pleased for the horse and the owners.
'He`s had a hard race, he`ll know he`s been in a race tomorrow and he deserves a break now.'
And Eddery added: 'He`s a tough horse, I had to try and get him to relax in front because he can go a bit.
'He`s improving and he got the trip really well.'
Boreas reportedly suffered an over-reach during the race and was taken to the veterinary area for treatment afterwards.
Michael Kinane notched his fourth winner of the Ebor meeting at York as Prince Alex obliged in the opening race on the second day.
He kept on well all the way to the line to defeat Nooshman by three parts of a length with Mastermind third.
