In the early 1990s he spent four seasons at Warren Place as Assistant to Henry Cecil – years that ran from Commander In Chief’s Derby victory up to Bosra Sham’s 1,000 Guineas win. This was followed by a year in New York overseeing Bobby Frankel’s string whilst Bobby remained in California, and a further three years with Luca Cumani which included High Rise’s Derby victory.
