Win rate and top-3 rate will show once this horse has raced.
O'Donoghue's yard has already sent out 7 winners this season, so Harmonising is joining a string in good form. Debut runners are always a gamble — you cannot know how a young horse will handle the noise, the crowd, the other runners, or the simple strangeness of racing until it actually happens. What you can say is that the pedigree looks workable for a 2-year-old, and the stable has the form to suggest they know how to get a young horse ready. How Harmonising performs on the day will tell you everything that matters.
