Amadeus Mozart

What makes Amadeus Mozart worth watching is who he is and where he could be heading. He is trained by Aidan P O'Brien at Cashel in County Tipperary, one of the most powerful yards in the world — a stable that has already sent out 144 winners this season alone. When O'Brien describes a young horse as "the type for a Derby trial", that is not throwaway praise. It is a signal that the team see genuine middle-distance Classic potential in him. His breeding backs that up too: he is out of a Galileo mare, and Galileo-bred horses have an exceptional record at the biggest mile-and-a-half occasions in Europe.

The Curragh win came over seven furlongs, but the trainer's comments suggest that trip was just a starting point. Stepping up in distance is the plan, and with his pedigree, there is every reason to think he will relish it. He raced just yesterday, so he is very much an active horse right now, with his best days almost certainly still ahead of him.
