RYAN MOORE'S position as British racing's leading Flat jockey was emphasised again by a treble in the first three races at Newmarket yesterday, including the Group One triumph of Integral in the Qipco Falmouth Stakes.

The greater praise could be attached to the 30-year-old's tactical masterclass from the front aboard Arabian Queen in the Duchess of Cambridge Stakes but the vigorous underlining of his talent came in the main event.

Integral encountered the softest ground of her brief but impressive career as she made her top-level breakthrough, beating Clive Brittain's Rizeena, the horse Moore had ridden to victory in the Coronation Stakes.

The Cheveley Park-owned and bred filly had been another Royal Ascot footnote for the jockey in the Duke of Cambridge Stakes and she was consequently sent off the 15-8 favourite.

Last year's 1000 Guineas winner Sky Lantern, a controversial runner-up here 12 months ago, was sent to the head of affairs but it developed into a battle between two of Moore's regular mounts, and the elder filly was two lengths too strong up the final hill.

Moore said: "It was always going to be a messy sort of race. I thought I was on the best horse and I wanted to keep it simple. I was in front earlier than I wanted to be but she's improving and hopefully will continue to get better. I see no reason why she shouldn't."

Sir Michael Stoute, Integral's trainer said: "She hasn't been on this sort of ground before but we wanted to find out if she would handle it.

"She's by Dalakhani and very few of those don't go on this sort of ground. She is in the Sussex Stakes at Goodwood, although I don't know if we will take on the colts. She's well entered."

Owner Jeff Smith and trainer David Elsworth enjoyed the latest high in what has been a long-running partnership when juvenile Arabian Queen (4-1) lowered the colours of Andre Fabre's odds-on French raider High Celebrity.

The pair's greatest moments together came through the popular stayer Persian Punch but another of the stars in the purple and blue silks was Barshiba, Arabian Queen's dam.

Moore sent his mount straight into the lead on her first attempt at six furlongs and he gradually wound up the gallop with the help of the rail, never letting Maxime Guyon get too close and finishing a length and a quarter in front.

The first leg of the Moore treble came via Sylvester Kirk's Nakuti (9-2) in the Price Bailey EBF Stallions Fillies' Handicap.
