Quadrilateral caps a big week for Frankel with Group 1 winner number ten

Quadrilateral continued her rapid ascent of the juvenile ranks when claiming the bet365 Fillies' Mile at Newmarket on Friday, and in so doing gave her sire Frankel his tenth Group/Grade 1 winner.

The filly is Frankel's second elite level-winning two-year-old after his first-crop daughter Soul Stirring, who landed the Hanshin Juvenile Fillies in Japan.

Quadrilateral's success also means that her sire has doubled his top-flight tally of winners this year, with five new Group 1 scorers appearing on his burgeoning stud record in 2019.

The first of this year's Group 1 winners was Dream Castle, who landed the Jebel Hatta out in Meydan. Anapurna then gave the Banstead Manor Stud resident his breakthrough domestic Classic success with victory in the Oaks. The Meon Valley Stud homebred added to her haul when landing the Prix de Royallieu on Arc weekend.

Next came Cheveley Park Stud's Veracious, who won the Falmouth Stakes, before Logician gave Frankel a second British Classic winner with an impressive victory in the St Leger.

With four crops of racing age on the ground, Frankel has now supplied 79 stakes performers, among which are 38 Group winners and ten Listed scorers.

The lengthy list of successes mentioned above has undoubtedly heightened the demand for Frankel's progeny at public auction, as evidenced at Book 1 of the Tattersalls October Yearling Sale this week.

A total of 22 lots by the son of Galileo sold for an aggregate of 10,300,000gns and, having been bred at a fee of £125,000, for an impressive average of 468,180gns. He sired the sale's second-most expensive offering, the half-brother to Derby and Arc hero Golden Horn, who went the way of Godolphin for 3,100,000gns.

Friday's racecourse success also means that Khalid Abdullah's Juddmonte breeding operation has been represented by four homebred Group 1 winners this year, a list headed by the mighty Enable.

The daughter of Nathaniel won the Coral-Eclipse, King George VI and Queen Elizabeth Stakes and the Yorkshire Oaks before a heart-breaking near-miss in her bid to land a hat-trick of Prix de l'Arc de Triomphes.

Juddmonte's other Group 1 winners this year are crack two-year-old Siskin, a son of First Defence who landed the Phoenix Stakes, the aforementioned St Leger hero Logician and Quadrilateral.

Fine female line

Frankel is not the only Juddmonte celebrity in Quadrilateral's pedigree, as she hails from a family steeped in Group 1 success. She is the fourth foal out of the winning Mizzen Mast mare Nimble Thimble, who is the dam of two other scorers in Boardman, by Kingman, and Balestra, a son of Bated Breath.

Nimble Thimble is a half-sister to Three Valleys, the son of Diesis who promised so much when he won the Coventry Stakes by eight lengths at Royal Ascot in 2003.

However, he flopped in the Phoenix Stakes on his next outing and, while he did bounce back to claim the Middle Park Stakes, he was later disqualified in controversial circumstances after testing positive for clenbuterol.

While Quadrilateral's racing career has not yet spanned two months, her breeder has been nurturing her family since the early 1980s, following the private purchase of Nimble Thimble's third dam Sookera, a Cheveley Park Stakes winner by Roberto who had raced for Robert Sangster.

Nimble Thimble and Three Valleys are out of Skiable, a Listed-placed Niniski half-sister to Juddmonte's blue hen Hasili.

The famed producer is the dam of five elite winners – namely Banks Hill, Cacique, Champs Elysees, Heat Haze and Intercontinental – as well as another high-class performer in Dansili, who went on to sire 21 top-flight winners during his stallion career at Banstead Manor Stud.

Quadrilateral is not the first example of Frankel working with this family, as it is also the source of the Group 3-winning Mirage Dancer, who is out of Heat Haze, and this season's Prix de Sandringham winner Obligate, who is out of Hasili's unraced daughter Responsible.

Nimble Thimble also has a yearling filly by Frankel, as well as a colt foal by Kingman. She was covered by Banstead Manor Stud newcomer Expert Eye this season.
