The astonishing start to his stud career made by the Japanese sire, Deep Impact, continued at the week when he enjoyed a graded stakes double that included a victory by his son Deep Brillante in the Japanese Derby (gr. I). Almost inevitably, Deep Impact is a son of the Halo stallion Sunday Silence. The status of Sunday Silence as not only the greatest Japanese stallion of his era, but arguably the greatest of all time, is well-established.  His importance, however, goes well beyond such parochial considerations, as Sunday Silence achieved something far more significance than local domination, single-handedly raising the international standing of the Japanese-bred racehorse.

It was Sunday Silence’s son, Stay Gold, who defeated Ekraar for the Hong Kong Vase (gr. I) to become Japanese-sired horse achieved an international win at the highest level. Subsequently, other Sunday Silence offspring got in on the overseas act: in 2002, Sunday Joy, bred to Southern Hemisphere time, captured the Australian Oaks (gr. I); in 2005, Hat Trick took the Hong Kong Mile (gr. I); and the following year the Sheema Classic (gr. I) fell to Heart’s Cry. The stallion sons of Sunday Silence were also quick to prove thay could get runners that were effective on the world stage, their offspring winning such races as the American Oaks (gr. I), Melbourne Cup (gr. I), Sheema Classic (gr. I), and in the shape of Victoire Pisa, the 2011 Dubai World Cup (gr. I). Two of Sunday Silence’s exported sons have also sired European Champions:  Divine Light – who first stood in France and then Turkey – being represented by Natagora, Champion European Two-Year-Old Filly in 2007, and heroine of the English 1,000 Guineas (gr. I) the following year, and the U.S.-based Hat Trick, coming up with last year’s European ChampIon Two-Year-Old Colt Dabirsim in his first crop.

As indicated by the above, as a group, the Sunday Silence stallions have done very well. In fact ten of them have sired group or grade one winners overseas, and at least 20 individual sons have sired group or grade one winners.  Despite this broadly shared level of success until recently there has remained a question as to whether Sunday Silence had left a definitive heir. This is a far from unique picture, and one can parallel it with the greatest European sire of the recent – or perhaps any other era – Sadler’s Wells. And, just as Sadler’s Wells had to wait – as far as Europe was concerned for Montjeu, and then Galileo (who arrived in his thirteenth crop), for a true heir so it is with Sunday Silence’s potential successor, Deep Impact, who was a member of the tenth of his sire’s eleven crops. Just as Sunday Silence was the best runner to represent his sire, Halo, Deep Impact was the best runner to represent Sunday Silence. More that, however, he established himself as very possibly the best racehorse bred in Japan. A winner of 12 of 14 starts, his victories included the Japanese Triple Crown, Japan Cup (gr. I), Takarazuka Kinen (gr. I), and Spring Emperor’s Cup. On his one foray outside of Japan, he was an excellent third in the Prix de l’Arc de Triomphe beaten a neck and ½ length by Rail Link and the strong-closing Pride, with Hurricane Run, Shirocco and Sixties Icon among those behind (although he was subsequently he was disqualified for a positive test for Ipratropium)

Deep Impact’s first crop are only four-year-olds of 2012, and that crop has already yielded ten stakes winners, eight of them graded. The stars have been Real Impact, who captured the one mile Yasuda Kinen (gr. I), and Marcellina, successful in the Oka Sho-Japanese 1,000 Guineas (gr. I). The graded winners Danon Ballade (second Japanese 2,000 Guineas (gr. I) and Tosen Ra (third Japanese St. Leger (gr. I)) are also classic placed, and graded winner Donau Blue also took second in the Victoria Mile (gr. I). Remarkably, Deep Impact’s second have already surpassed those efforts. Despite still only being in the spring of their three-year-old career, 13 of there number have already captured black-type events. With a view to the future, perhaps the most significant is Beauty Parlour, who took her record to four wins in four starts, when following up a victory in the Prix de la Grotte (gr. III), with a triumph in the French 1,000 Guineas (gr. I). A sister to Barocci, a listed winner in France last term, Beauty Parlour was bred by the Wildenstein family, who sent her dam, Bastet, on two trips to Japan to visit Deep Impact. One would suspect that it is only a matter of time before more international breeders begin to follow this precedent . On the domestic front, Deep Impact’s three-year-olds have taken three of the four classic races run in Japan in 2012. The filly, Gentildonna (a sister to Donau Blue), has captured both the the Japanese 1,000 Guineas (gr. I) and Japanese Oaks (gr. I). In addition to Gentildonna and Deep Brillante, Deep Impact has a third grade one one winner from this crop in the shape of Joie de Vivre, successful last yea rin the Hanshin Juvenile Fillies Stakes (gr. I), and the crop also inclues graded scorers Tosen Homareboshi, World Ace, Verxina (second to Gentidonna in the both the 1,000 Guineas and Oaks), Historical, Real Deal, and Adam’s Peak.

Out of the group one winning Alzao mare, Wind in Her Hair, Deep Impact has a pedigree is an outcross at five generations (although like any Sunday Silence with Northern Dancer in the dam, he has Almahmoud as granddam of both that horse and Halo). We can also note the combination of Halo and the similarly-bred Sir Ivor (broodmare sire of Alzao) 2 x 4, and Deep Impact is one of 19 Sunday Silence line stakes winners with Sir Ivor in the dam. A product of the Sunday Silence/Northern Dancer cross, Deep Impact has already begun to prove very effective when bred back over Northern Dancer line mares. Beauty Parlour and Barocci are out of a mare by Giant’s Causeway (by Storm Cat), and has another cross of Halo, through Giant’s Causeway’s broodmare sire, Rahy, who is out of the Halo mare Glorious Song. Gentildonna and Donau Blue are out of Donna Blini, a daughter of the Danzig horse, Bertolini (he is a three-parts-brother to Green Desert, who as a Northern Dancer/Sir Ivor cross, might also go well here). Donna Blini’s dam is by Lyphard’s Special, giving a double of Lyphard. This duplication already appears in at least seven of Deep Impact’s stakes winners, including Deep Brillante (fourth dam by Lyphard), Smart Robin (out of a mare by Lyphard), and Aquamarine (out of a mare by Alzao, so having that horse 3 x 2).

Marcellina is out of the Prix d’Astarte (gr. I) winner, Marbye, a daughter of Marju (by Last Tycoon), who is bred on a parallel Northern Dancer/Sir Gaylord cross to Alzao. Similarly, Joie de Vivre and her brother Tosen Reve, are out of top-class runner Biwa Heidi, a daughter of Caerleon (by Nijinsky II), and a Lord Gayle mare, so another Northern Dancer/Sir Gaylord cross.  From mares by Northern Dancer’s son, Northern Taste – who preceded Sunday Silence as the dominant sire in Japan – Deep Impact has graded winners Tosen Homareboshi and Historical. Two of Deep Impact’s stakes winners, are out of mares from the Nureyev line, Best Deal from a daughter of Marchand de Sable (by Theatrical) and Frere Jacques out of a daughter of Nureyev himself. From the sire line of Sadler’s Wells (reverse Northern Dancer/Hail to Reason cross to Deep Impact), Deep Impact is sire of Adam’s Peak, who is out of a mare by Singspiel (out of Glorious Song by Halo, so a reverse Northern Dancer/Halo cross to Deep Impact). Boreas, the other Deep Impact stakes winner out of a Northern Dancer line mare, is from a daughter of French Deputy (from the Deputy Minister line).

Deep Impact has also begun to work well with Mr. Prospector line mares. His twice classic placed daughter, Verxina, is particularly interesting in this regards. She is out of a mare by Machiavellian (dam by Halo), and her third dam is Halo’s Champion daughter, Glorious Song (Verxina, therefore has Halo 3 x 4 x 5 (along with a cross of the similarly-bred Sir Ivor), and Northern Dancer 5 x 4, along with a half-sister to that horse, for a total of six crosses of Almahmoud. A similarly intriguing pedigree is owned by Tosen Ra (a half-brother to Flower Alley, sire of I’ll Have Another) who is out of a mare by Lycius, with a second dam by Sadler’s Wells. As mentioned, she is inbred by 4 x 4 to Lyphard, and her third dam is a half-sister to that horse. Danon Ballade, out of an Unbridled mare, is also inbred 3 x 3 to Halo, and her second dam, Angelic Song, is a sister to Glorious Song, who we’ve already seen in the dams of Deep Impact stakes winners through her sons Rahy and Singspiel. Deep Impact also has stakes winner Para la Salud out of the Chilean-bred Tanta Suerte, who is a daughter of Stuka (by Jade Hunter, a Mr. Prospector/Lypard cross), with a second dam by Stagecraft, a Sadler’s Wells son who brings in another Lyphard cross.

Deep Impact has also enjoyed success with some strains less commonly found in Japan. His first grade one winning son, Real Impact, is out of a mare by Meadowlake. The cross of Halo line stallions over Meadowlake mares has produced four graded winners, and not only gives linebreeding to Nothirdchance (dam of Hail to Reason), but brings together  Halo and Prince John (out of a half-sister to Halo’s broodmare sire, Cosmic Bomb). Prince John appears in three other Deep Impact stakes winners, including Deep Brillante, who is out of a mare by Loup Sauvage, a son of Riverman. Deep Brillante’s second dam is by Akarad, a grandson of Busted, sire of the second dam of Deep Impact. Far more of an outcross is World Ace, who is out of Mandela, an Acatenango half-sister to Manduro. The same is true of Ardent, a three-year-old black type winner who is out of a daughter of Kaldoun, a son of Caro.
