What does give Dover Street a solid foundation is the yard sending him out. Richard Hannon, based at Herridge in Wiltshire, is one of the most productive trainers in Britain, and with 115 winners already on the board this season alone, this is not a small operation finding its feet. Hannon has a long track record of knowing exactly when a young horse is ready to run, which means Dover Street's appearance on a racecourse today is unlikely to be accidental. First-time-out runners from a yard firing at this rate are always worth watching closely, even if the horse itself is an unknown quantity. Everything starts here.
