Question: We were wondering why Rahy crossed on Trempolino is a C TrueNicks but Runaway Groom (through Cherokee Run) crossed on Trempolino is an A when they are both Blushing Groom sire lines. Mare is Emeralino. Your thoughts please....

Answer:
Hi Brian,

Thank you for your enquiry.

When we look at a Cherokee Run (TrueNicks, SRO)/Emeralino mating, there are not enough starters or stakes winners by Cherokee Run out of mares by Trempolino - or by his sire, Sharpen Up, or by his grandsire, Atan - to achieve a valid rating. The next default is to look at Runaway Groom (sire of Cherokee Run) and sons with mares by Trempolino. This still doesn't yield enough starters or stakes winners, so the next default is Runaway Groom and sons with Sharpen Up-line mares. There has been a graded stakes winner by Runaway Groom outof a mare by Sharpen Up, and a stakes winner by Cherokee Run out of a mare by a son of Sharpen Up, and a graded stakes-placed horse by Runaway Groom out of a Trempolino mare. When compared with all other foals by Runaway Groom and the sons that were bred to Sharpen Up-line mares, and with all other foals produced by the Sharpen Up-line mares bred to Runaway Groom and his sons, the cross significantly outperforms opportunity.

When we move to the Rahy/Emeralino mating, their are insufficient stakes winners and starters on the cross of Rahy with mares descending from Trempolino, Sharpen Up, or Atan. The next default is Rahy's sire, Blushing Groom, with Trempolino mares, and that has also not had enough starters or stakes winners to achieve a rating. So then we default to Blushing Groom and sons with Sharpen Up-line mares (note that we have still only gone back one generation from the sire and broodmare sire). Overall, Blushing Groom and his sons have only slightly outperformed opportunity when mated Sharpen Up line mares, so this mating is only rated C.

I hope this helps.

Best regards
