Sons of Deep Impact, St. Leger Trial and Two Thousand of Broodmares

Despite achievements of stallions such as Stay Gold, Fuji Kiseki, Neo Universe, Heart’s Cry, Gold Allure, Special Week, Daiwa Major or Agnes Tachyon is without any doubt that the most successful sire of Sunday Silence at stud is the champion of Japanese stallions Deep Impact. Although only fifteen, he is just two winners from the milestone of a 100 black-type winners, an excellent result for a stallion with just eight crops on the racecourse.

Even a poor mathematician will find it easy to calculate that if Deep Impact has the eight crop of his progeny on the racecourse, the first ones were foaled in 2008. Nine years, it is nearly the time when the first of his successful sons will have their own progeny on the racecourse. And it is indeed the case with Deep Impact whose first grandsons score stakes achievements. The very first of them was the three-year-old Seda Brillantes, the winner of the Gr.3 Radio Nikkei Sho over 1,800m at Fukushima in early July. The second, and the first Gr.2 winning grandson of Deep Impact, scored last Monday in the trial of the Japanese St Leger, St Lite Kinen over 2,200m – Mikki Swallow.

Seda Brillantes comes from the first crop of the 2012 Tokyo Yushun (Japan Derby) winner Deep Brillante, Mikki Swallow is by Tosen Homareboshi, who finished third in the same edition of the Japan Derby and whose biggest achievement was the victory in the Gr.2 Kyoto Shimbun Hai. Deep Brillante and Tosen Homareboshi were, together with the unraced Kimonno Kashiwa, the first sons of Deep Impact at stud in Japan. Since then their number has risen significantly and only last year, there were ten of his sons at stud in Japan. The thirteen sons who were at stud in Japan in 2013-2016 (and most of whom still are) have covered a total of 1,998 mares. This is an impressive number but what is perhaps even more interesting is that one seventh of them were covered in a single season by a single stallion – last year in the first season of the Japanese champion and Derby winner Kizuna, who covered 269 mares in his introductory season at Shadai Stallion Station. The winner of an Arc trial, the Gr.2 Prix Niel, placed fourth in the Arc itself, has struck a new Japanese record in the number of mares covered by a debuting stallion, exceeding Lord Kanaloa who had 250 partners in 2014.

Six of thirteen Deep Impact’s sons at stud in Japan have covered over 100 mares in a single season which is not bad. Sons of Deep Impact, however, are to be found also elsewhere than in Japan. After two seasons in Japan, the Japanese Gr.2 winner and the third in the Satsuki Sho (Japanese 2,000 Guineas) Danon Ballade moved to Allevamento di Besnate, Italy, with a fee of EUR 6,000. Haras de Grandcamp, France, is the home of the two-time Gr.3 winner Martinborough, 3/4 brother to the Gr.1 winners Verxina and Vivlos of the Glorious Song family, Swedish breeders can quench their thirst for Deep Impact’s blood by opting for the winner of the Prix Omnium (L) and the runner up in the Prix du Prince d’ Orange (Gr.3) Barocci, full brother to the French classic winner Beauty Parlour. In the United States, the unraced Dowsing bred by Flaxman Holdings Ltd., debuted this year at Holden Thoroughbred and Running Quarter Horse Farm, Indiana, with a fee of USD 10,000.

Outside Japan Deep Impact’s sons are quite unlikely to cover three-digit numbers of mares, given the fact there was not comparable demand even for Sunday Silence’s sons as there was in Japan. The results of this year’s two-year-olds by Dabirsim (Hat Trick) may, however, help Sunday Silence’s grandsons to win more trust outside Japan than his sons had.
