Scat Daddy sired eight Gr.1-winning sons (including one in Japan), the eldest of which - No Nay Never - is firmly established as one of Europe’s best young sires. This bodes extremely well for Justify, who rapidly proved himself as Scat Daddy’s outstanding son with a sequence of six victories which saw him develop into only the 13th American Triple Crown winner - and only the fifth since 1948. In winning from 7 to 12 furlongs, Justify displayed an exceptional blend of speed and stamina, and he is also an exceptional physical specimen.
There is every reason to expect Justify’s versatility to extend to his stallion career. Scat Daddy owed his total of 50 GSWs in the northern hemisphere to no fewer than 46 different broodmare sires. This suggests that Justify will also work with a wide range of bloodlines.
With the nearest of Justify’s three lines of MR PROSPECTOR being in the fourth generation of his foals there’s ample scope to add extra lines. Scat Daddy sired the very successful No Nay Never from an ELUSIVE QUALITY mare and much of his phenomenal success in Chile was based on mares by Gone West’s son SEEKER’S REWARD, with the U.S. Gr.1 winner Dacita being an excellent example.
It was a grand-daughter of Forty Niner, by END SWEEP, who produced Scat Daddy’s very fast daughter Acapulco. Mares by DISTORTED HUMOR have obvious appeal.
Scat Daddy also sired Graded winners from mares by SMART STRIKE and his son CURLIN. Scat Daddy’s son No Nay Never has a Gr.2 winner out of a mare by Smart Strike’s son ENGLISH CHANNEL. Two other grandsons of MR PROSPECTOR which have done well with Scat Daddy are STREET CRY (broodmare sire of Gr.1 winners Skitter Scatter and Con Te Partiro) and THUNDER GULCH.
EMPIRE MAKER mares have 20% SWs with Scat Daddy. Scat Daddy has also sired GSWs from mares by UNBRIDLED’S SONG’s sons BUDDHA (Gr.1 wnr Valid Point), SONGANDAPRAYER, FIRST DEFENCE and ROCKPORT HARBOR.
Scat Daddy was successful with the SEATTLE SLEW line, siring Gr.1 winners from mares by HOUSTON and SKY MESA. TAPIT mares create 4x3 to PULPIT and 4x5 to MR PROSPECTOR, while mares by MINESHAFT, MALIBU MOON, CONGRATS and FLATTER create 5x3 to A.P. INDY and 4x4 to MR PROSPECTOR.
DANZIG line mares are good options as BOUNDARY is broodmare sire of Scat Daddy’s 2020 Gr.1 winner Combatant. Scat Daddy proved tremendously effective as a sire of European turf horses, even though he raced exclusively on dirt – as did Justify. European breeders looking for an outcross should consider using him on their DANZIG line mares, especially as No Nay Never’s two-time Gr.1 winner Ten Sovereigns has a dam by EXCEED AND EXCEL and his 2020 Gr.1 2yo winner Alcohol Free is out of a HARD SPUN mare.
Scat Daddy’s exceptionally fast Lady Aurelia is inbred 4x3 to STORM CAT, her dam being by FOREST WILDCAT.
Scat Daddy sired the Gr.1 winner Nickname from a grand-daughter of El PRADO, so daughters of MEDAGLIA D’ORO and KITTEN’S JOY should be considered for Justify.
HOLY BULL mares did very well with Scat Daddy, notably producing the top sprinter Caravaggio.
