The stable sending this three-year-old out is one of the most powerful in British racing. William Haggas trains from Newmarket in Suffolk, and his yard has already sent out 170 winners this season alone — a number that speaks for itself. To put that in context, most trainers would consider 20 or 30 winners a very solid year. Haggas is operating at a completely different level, which means horses that emerge from his string tend to have been well prepared before they ever set foot on a racecourse.
For a first-time runner, yard form and breeding are really the only clues available, and on both counts Yimmna has plenty going for it. Whether that translates into a winning debut is another matter entirely — but this is not a horse anyone should be ignoring.
