Win rate and top-3 rate will show once this horse has raced.
First-time racers are always unknowns. Some take to it naturally; others need time to settle and learn. Without any clue from his breeding or any prior form, all we can do is watch and see whether New Addington Boy runs with pace, stays the distance, or shows signs of the ability his the yard believe he has. That first race will tell you far more than his pedigree ever could.
