On which horse did Lester Piggott win his final Classic?  At the time of his retirement, for the first time, in 1985, Lester Piggott had won 29 British Classics, including a record nine wins in the Derby, and won the jockeys’ title 11 times. Two years later, he admitted defrauding Her Majesty’s Revenue and Customs of £3.25 million and was sentenced to three years’ imprisonment. Piggott served 366 days and was released in 1988.

Two years later, Piggott resumed his riding career, famously winning the Breeders’ Cup Mile at Belmont Park, New York on Royal Academy, trained by Vincent O’Brien, in 1990. Two years later still, in 1992, improved upon his unprecendented record in British Classics by winning the 2,000 Guineas on Rodrigo De Triano, trained by Peter Chapple-Hyam.

The son of El Gran Senor had lost his unbeaten record when only fourth in the Greenham Stakes on his reappearance at Newbury the previous month, when ridden by Willie Carson. However, ridden for the first time by Piggott, Rodrigo De Triano won the 2,000 Guineas at Newmarker and followed up in the Irish equivalent at the Curragh two weeks later, again under Piggott. Later the same season, the partnership also won the Juddmonte International Stakes ar York and the Champion Stakes at Newmarket. Piggott finally retired for a final time in October, 1994, with 4,493 winners to his name, including 30 British Classic winners.
