Hell 3.89 he would be studded out for a future Triple Crown winner!! 2nd Secretariat!!
For those too young to know who Secretariat was...he was the fastest horse relative to its competition...or any mammal relative to its own species including humans...that has ever competed. It ran the Belmont Stakes so fast that in the videos, the other horses were not even in the camera shot AT ALL at the finish because they were a quarter of the track almost behind him. He won by 25 something horse lengths IIRC.. the largest margin of victory every in a TC level race....and his record times stood for like 50 plus years AFTER he set them despite major improvements in science, breeding, medicine, you name it.
