Kingman's grandsire Green Desert is discussed on Oasis Dream's page. Needless to say he has proven to be a very influential sire of sires through the likes of Oasis Dream, Cape Cross and Invincible Spirit. His grandsons are also making their mark at stud – Sea The Stars and Showcasing are amongst the leading sires in Europe.
Invincible Spirit is also being ably represented by his stallion sons. Australian Group 3 winner I Am Invincible, who was second to Takeover Target in a 6f Group 1 contest, has quickly established himself as one of the leading sires in the Southern Hemisphere. He was the leading first season sire in Australia in 2013-14 and in 2018-19 made history by siring a record 28 Australian stakes winners in a single season, including four Group 1 winners. To date Invincible Spirit’s sons have sired over 200 stakes winners - but none have made a better start than Kingman.
Invincible Spirit is very similar in many ways to Kingman's “uncle” Oasis Dream. They are both sprinting sons of Green Desert who have staying influences in their pedigrees. Invincible Spirit is a son of the 1990 Prix de Diane winner Rafha – whose outstanding stud career produced seven blacktype performers in total including leading sire Kodiac, and the dam of Group 1-winning two-year-old Nayarra. As with Oasis Dream, Invincible Spirit has proven himself to be not only a world-class stallion, but also an extremely versatile one, siring Group 1 winners at distances from 5 to 10½f. Some of his stars include the outstanding Moonlight Cloud, Classic winners Magna Grecia and Lawman, top miler Charm Spirit, leading two-year-olds Shalaa and National Defense and the high-class sprinters Mayson, Fleeting Spirit, Profitable and Signs Of Blessing – but Kingman has achieved the highest Timeform rating of any of Invincible Spirit’s progeny.
