Siyouni is one of 27 Group 1 winners by Cheveley Park Stud's sprint star and outstanding stallion Pivotal (by Polar Falcon) and he achieved his top win at the age of two, taking the Group 1 Prix Jean-Luc Lagardere-Grand Criterium over seven furlongs at Longchamp.
He failed to win from six starts as a three-year-old but was placed in both the Group 1 Prix Jean Prat and Group 1 Prix du Moulin de Longchamp and improved his Timeform rating from 117 to 122. Being a high-class son of the sire of Kyllachy and out of a stakes-winning half-sister to Group 1 star Slickly (by Linamix), he went to stud as a promising prospect.
The fee for his first four years at Haras de Bonneval was just €7,000, but since then it has soared and he will busy this season at €75,000. Classic and triple mile Group 1 heroine Ervedya heads his current tally of 20 stakes winners, a roll of honour that also includes the Group 1-placed pattern winners Le Brivido, Siyoushake, Spectre and Volta, recent Australian Group 2 scorer Aylmerton, and this afternoon's impressive Group 3 Prix Vantaux winner Barkaa.
Of course, Siyouni is also the sire of Laurens, the Karl Burke-trained filly who held on in game fashion for a narrow victory in the Group 1 bet365 Fillies' Mile Stakes at Newmarket in October. This came a month after she beat Dark Rose Angel by a head in a blanket finish for the Group 2 William Hill May Hill Stakes over the same trip at Doncaster.
Laurens, who was bred by Bloodstock Agency Ltd and made £220,000 at the Goffs UK Doncaster Premier Yearling Sale, made a winning debut over seven furlongs at that same venue in mid-July and her only other start to date came at Deauville in August when she chased home Polydream in the Group 3 Shadwell Prix du Calvados.
It is fair to say that she was lucky to win the Newmarket race, as the Aidan O'Brien-trained runner-up September met with trouble in running and just failed by a nose at the line. Timeform, who had her on 105p before the race, raised her only to a mark of 112 – her official handicap figure is 113.
Laurens, a half-sister to two National Hunt winners, is the fourth foal out of Recambe (by Cape Cross), which makes her inbred 4x4 to Danzig (by Northern Dancer). Her dam's siblings include Listed Newmarket Stakes winner and top Hong Kong performer Salford Mill (by Peintre Celebre), and her grandam is the stakes-placed Razana (by Kahyasi).
That daughter of triple winner Raysiya (by Cure The Blues) is a half-sister to four blacktype producers, one of whom was herself a listed winner and two of whom are of particular note.
Profit Alert (by Alzao), a full-sister to stakes winner and blacktype producer Raysiza, is the dam of the high-class miler Shifting Power (by Compton Place). He won the Listed European Free Handicap and Listed Royal Windsor Stakes, he chased home Kingman in the Group 1 Irish 2000 Guineas, was a one-length runner-up to Charm Spirit in the Group 1 Prix Jean Prat, and was third to Custom Cut in the Group 2 bet365 Mile at Sandown.
Ribot's Guest (by Be My Guest), the other mare of note, was unraced, but her son Mickdaam (by Dubawi) won the Group 3 Chester Vase and her daughter Kinnaird (by Dr Devious) won the Group 1 Prix de l'Opera before going on to success at stud.
Kinnaird is the dam of Group 2 Royal Lodge Stakes winner Berkshire (by Mount Nelson), who is in his first season at Haras de Sorelis in France, and she is the grandam of young Coolmore stallion Ivawood (by Zebedee).
That grandson of Invincible Spirit (by Green Desert) won both the Group 2 July Stakes and Group 2 Richmond Stakes as a two-year-old, was a nose runner-up to Charming Thought in the Group 1 Middle Park Stakes that autumn, and filled third place in the Group 1 2000 Guineas and Group 1 Irish 2000 Guineas the following spring, both won by Gleneagles. His top-priced first-crop foal made 105,000gns in Newmarket in late November.
Laurens holds entries in the Group 1 Qipco 1000 Guineas, Group 1 Irish 1000 Guineas, Group 1 Poule d'Essai des Pouliches (French 1000 Guineas), Group 1 Prix Saint-Alary, Group 1 Prix de Diane (French Oaks), and Group 1 Darley Irish Oaks.
She needs to improve quite a bit on her two-year-old ratings to be up to winning any of those, but she is arguably bred to be better at the age of three than she was as a juvenile, and there is every reason to hope that she can figure prominently in the best mile to 10 and a half-furlong fillies' races of 2018, possibly also staying 12 furlongs.
