Pat Eddery continued his run of good form as he took the riding honours at the today's Ascot Heath meeting with a 47-1 double on board Papabile and Blue.
Eddery was at his best aboard 5-1 chance Papabile as a gamble on the Geoff Wragg-trained Rosse came unstuck in the opening London Clubs Fern Hill Rated Stakes (Handicap).
Rosse had been backed down from 5-2 to 5-4 with Ladbrokes this morning but flattered to deceive as William Jarvis's filly was driven home by Eddery to score by a head from Mystify with Coco a length and half further back in third.
'She's a full sister to Grand Lodge and she is very similar, very tough with all of his will to win,' said the winning trainer.
'She will make a lovely broodmare in time but I think she has another nice race in her.
'She is improving fast and there is possibly a Group Three race in her. We'll probably go abroad for that.'
Jarvis paid tribute to Eddery's role in today's victory, adding: 'Pat was very brilliant on her - he is the ultimate professional and is still riding as well as ever.'
Eddery also had a big say in the victory of Blue who was half a length too good for Sharp Play in the Ladbroke Stakes (Showcase Handicap).
The 7-1 shot's success continued the fine form of trainer Amanda Perrett who had her first Royal Ascot success with Give The Slip in the King George V Stakes earlier in the week.
'The last three runners have been winners,' she said after greeting Blue into the winner's enclosure.
'This winner means as much as any really. Ken and Sylvia Buchanan (Blue's owners) were with Dad (former trainer Guy Harwood) for a long time and they stayed and supported us.
'This horse had a good two-year-old career and then lost his way at three - thank goodness he has come back now.
'Pat put me right - we went too far at Newmarket last time out - and he said go back to a mile and a quarter and he will definitely win, thanks to Pat again.'
John Gosden's Manton yard has also performed with distinction at the Royal meeting and that form continued today with a double.
Port Vila kicked off the brace with a remarkable victory in the Listed Milcars New Stakes.
The 5-2 shot, who drifted in the market from 13-8, looked in trouble at the back of the field as they turned for home.
But jockey Richard Hills remained patient on the rails and when the gap eventually appeared the partnership took advantage and eventually wore down Rasm, also under the ownership of Hamdan Al Maktoum, by half a length.
Gosden said: 'At Ascot when you get shuffled back to last you have one choice, stay on the rail and pray for a gap, because if you attempt to come round you will always be the unlucky third.
'So you either, in that situation, look a genius or an idiot - a jockey can never look anything between the two.
'The gap came - Sheikh Ahmed's horse was about to close him in but fortunately rolled off the rail and we just got through.'
13-8 favourite High Walden was withdrawn after refusing to enter the stalls.
Hymn (11-8) completed the Gosden double when denying Modern British in the De Boer EBF Triumvirate Classified Stakes.
This victory sparked another double, this time for title-chasing jockey Kevin Darley, who had to bring his mount the longest-way round to achieve success.
Gosden said: 'I told Kevin to please go and make it if you want to - in small fields you have to do that.
'We were forced wide all the way but at the end of the day we were always in a striking position. I told Kevin not to bother covering him up - he relaxes.
'When they straightened up he could make a run and he got up and won.'
Darley's double was completed when Hejaziah justified 7-4 favouritism in the Brunswick Novice Fillies' Stakes.
Earlier, Compton Banker pulled of a 16-1 surprise to land the five furlongs Palan Stakes and could now be aimed at Glorious Goodwood's Stewards' Cup.
And Generous Ways, trainer Eric Alston and jockey Willie Supple repeated last year's victory in the Betterware Stakes.
