Galileo and the Sons of Doubly Sure
by Roger Lyons
The cross that yielded Cape Blanco (Galileo-Laurel Delight, by Presidium, by General Assembly), recent winner of the Dante S. at York, is formally an A nick based on the Sadler’s Wells-General Assembly cross. Galileo may never get enough opportunity with Presidium mares to confirm a simple sire-broodmare sire nick in the conventional way, but this is not a conventional nick.
The fact is that Galileo has done a lot better with mares whose ancestries contain Presidium’s dam, Doubly Sure, than he’s done with Secretariat-line mares. Seven of his 27 mates that had Doubly Sure in their ancestries produced superior runners by him, including Cape Blanco’s dam.
Now, Doubly Sure is also the dam of Kris and Diesis, both by Sharpen Up, and they both have simple A+ nicks with Galileo. Furthermore, the numbers say Galileo’s nicks with Kris and Diesis are not attributable to their sire line. Galileo has sired foals out of 53 mares that have Sharpen Up in their ancestries (the whole ancestry, not just the sire line), and the only mares among them that produced superior runners by Galileo are those that have Sharpen Up descending through either Kris or Diesis. None of the 27 mares that have Sharpen Up through strains other than Kris or Diesis produced a superior runner by Galileo. Yet, Galileo’s combined strike rate with Kris and Diesis is 6/24 (25% superior runners).
Overwhelmingly, the numbers point to Doubly Sure as the key factor, and that’s the proof that Cape Blanco is bred from a simple nick with her son, Presidium.
