What we do know is the breeding. Efsixteen is by Havana Grey, a sire who made his name producing fast, sharp two-year-olds built for sprinting. The mother's side traces back through Sakhee's Secret, another speed influence. Put those two together and you have every reason to expect a horse that wants to get out of the gate quickly and make an immediate impression, rather than one who needs time and distance to find its best.
The trainer is George Scott, who operates out of Newmarket — the heartland of British flat racing, where the gallops and competition attract some of the sharpest young horses in the country. His yard has sent out 52 winners already this season, which tells you this is not a small operation finding its feet. It is a stable in form, confident in its judgement, and when a yard like that puts a two-year-old on a track for the first time, they generally have a reasonable idea of what they have got. Whether Efsixteen lives up to the breeding and the surroundings, only the race itself will answer.
