The breeding is worth a look. The father is Churchill, one of the standout racehorses of his generation in Britain and Ireland, and the mother's side traces back to Smarty Jones — an American horse who became a genuine national story when he swept all before him as a three-year-old. It is a transatlantic mix, and breeders do not put those two names together by accident.
A Oliver's yard has sent out 20 winners already this season, which tells you this is not an outfit that fills races with also-rans. Twenty winners takes sustained effort and genuine horses, so when a yard like this puts a debutant on the track, it is reasonable to assume the horse has shown something at home worth getting excited about. Whether Westminster Waltz can back that up in public is the question only the race will answer.
