The mundane details of her eventual mating in the coming year are still being ironed out – much the same ado was made over the marriage of Queen Victoria –but the idea that Zenyatta could replicate herself by the mere act of insemination and foal birth is nuts. There was never, and never will be again, a Thoroughbred quite like Zenyatta.
