My own pinnacle/apex/zenith of breeding has been reached today.  I have bred my stud Gunslinger (142T/140D) to my mare OK Corral (136T/140D) and got a colt - The Duke (152T/152D).

He runs mid-pack, has 15 starts per year, peaks at age 5.5 and has a range of 7-15 furlongs.  He's a beast!

Just finished his 3 yo campaign- Junior of USA, Star of USA, All Rounder and World Turf Champ - total earnings over 270,000 for the year on 15 wins.   

What ended up being the top horse ever back in the day?  Did someone get into the 160s?
