Medina Spirit won the Kentucky Derby. Where did he get the speed and endurance?
Great Grandparents.

They are all great horses themselves, but, when one considers Seattle Slew and Bold Reasoning who was sired by Bold Ruler at Clairborn Farms; I would have bought the colt in a heartbeat, too.
Medina Spirit has some of the finest thoroughbred blood lines, including the fact Secretariat was sired by Bold Ruler. Bold Ruler wasn't much of a racehorse, but, he was a heck of a daddy.
If one is going to follow Medina Spirit, his career may very well follow that of Seattle Slew. Little known horse bought fairly cheaply at an auction, but, delivered a 1000 times his price.
The only other sire that turns my head is Princequillo.
When it comes to breeding Thoroughbreds,(click here) the wise money generally goes with the tried and true within the box of fashionable bloodlines. The wiser money will look outside the box and, once in a while, find gold where no one else would consider looking. Princequillo is one such Thoroughbred. He was like this his entire life....It is always the "Rags to Riches" stories that make the greatest sires. Isn't he a beauty and his strength as a sire still holds true today. You can still find him in the lineage somewhere.
If it weren't for the horse, the trainer is nobody.
