American Pharoah with authority

[Indian Charlie]

Mumtaz Mahal was known primarily for being speedy.

That and her profound effect on the future of the breed.

Rollo, thanks for taking the time to post those.

The first black type I found in AP's female line was a stakes winning half sister to his dam. She also produced a black type winner herself. Another half sister produced a black type runner.I have to go 5 generations back to a stakes winning dam who produced a turf sprinting stakes winner,a full sister to AP's 4th dam.There is black type sprinkled throughout the foals of the 5th dam.As a side note Fred Hooper bred the 4th and 5th dam as well as all of the black type runners.

The 3rd dam was the lone foal of the 4th, and the 3rd's best producing daughter was AP's grand dam.

I can't dispute the lack of "stamina siblings" through AP's female line compared to any of the horses you posted.However his grand dam's work is not yet completed.

The question I have to ask is how would AP's female line compare to the last 30 Kentucky Derby winners?
