What is not in doubt is the quality of the stable sending Blooming Rose out. Joseph Patrick O'Brien, based at Owning Hill in County Kilkenny, has already produced 171 winners this season alone — that is a remarkable volume of success and a sign of a yard operating at the very top of its game. When a horse comes from a stable that productive, it does not guarantee anything, but it does mean the preparation will have been serious and professional. First-time-out runners from the O'Brien yard are worth paying attention to, simply because they rarely arrive underprepared.
