On the breeding side, there are reasons to be interested. Bravaro's sire, Upstart, was a sharp American horse who showed plenty of speed during his career, and that quality has a habit of passing down. The dam's side adds another layer, coming from the Tamarkuz line — another American influence known for producing horses who tend to hit the ground running. Two speedy bloodlines on the same page suggests Bravaro may not need a long learning curve to find a competitive rhythm.
Beyond that, the honest answer is that nobody outside the yard truly knows what they have yet. The first race will tell everyone something — including, quite possibly, the team themselves.
