At two years old, The Bookkeeper is at the very start of a racing career. The breeding offers a few clues about what to expect: by Sioux Nation, a sire associated with speed and early maturity in young horses, out of a mare by Camacho, who was himself a sharp, quick sprinter. That combination suggests The Bookkeeper may be built for fast, short races rather than the staying tests that come later in a horse's development — though of course, only racing will tell us how much of that potential has been inherited.
First-time runners are always a leap of faith for anyone watching, but a two-year-old stepping out for the first time from a yard with 65 winners on the board this season is at least arriving with a good team behind it.
