You have to appreciate the irony.
The Kentucky Derby winner could not be any less “well bred”. Medina Spirit sold for $1,000 at a yearling sale. His sire (Protonico) is almost completely unknown, and MS is the first foal out of an unraced mare.
The Kentucky Oaks winner could not be any more well bred. Malathaat was a $1 million dollar yearling by the most expensive sire Curlin. Malathaat’s mother ran 4th in the Kentucky Oaks (she was the daughter of the great AP Indy), and Malathaat’s mom’s mother was a multiple graded 1 winner.
In horse racing anything is possible.
Actually the breeding of Medina Spirit is interesting if you dig a little deeper. The sire Protonico is a son of the versatile Giant’s Causeway. Protonico is by an AP Indy mare, whose mother was a graded stakes winner at 1 1/4 miles. MS’s dam is a granddaughter of the great stamina influence Dynaformer. The second dam is a daughter of Derby winner Unbridled.
Medina Spirit is really a plodder/plodder.
Of course, Mandaloun was a close 2nd in the Derby. He is a classic Brad Cox miler being stretched out to be capable of going 1 1/4 (Into Mischief out of a sprint oriented mare). 3rd place Hot Rod Charlie is a mix, Oxbow is a son of distance oriented Awesome Again, but the dam is by sprint oriented Indian Charlie.
My dream of Brooklyn Strong got a solid bump at the start and did little running.
What was impressive was the great 2nd run by Dream Shake in the Pat Day Mile.
