How many career wins did Lester Pigott have throughout his horse racing career?

Lester Keith Piggott (born 5 November 1935) is a retired English professional jockey. With 4,493 career wins, including nine Epsom Derby victories, he is widely regarded as one of the greatest flat racing jockeys of all time. He was known for his competitive personality, keeping himself thirty pounds under his natural weight.

Piggott began racing horses from his father's stable when he was 10 years old and won his first race in 1948, aged 12 years, on a horse called The Chase at Haydock Park.

In 1985 Piggott rode as a freelance, with big wins including the Prix de Diane for Andre Fabre aboard Lypharita, the 2000 Guineas for Michael Stoute on Shadeed and the Benson and Hedges Gold Cup and Irish Champion Stakes for Luca Cumani on Commanche Run. Piggott retired as a jockey at the end of the 1985 flat season and became a trainer.

He resumed his career as a jockey in 1990 and won the Breeders' Cup Mile on Royal Academy within ten days of his return. He rode another Classic winner, Rodrigo de Triano, in the 1992 2000 Guineas. His last win in Britain was in October 1994 and he officially retired in 1995; his last British ride was in the November Handicap on 5 November 1994, but he rode abroad through the winter of 1994/95, winning the Black Opal Stakes on Zadok in Canberra on 5 March 1995 before deciding not to return for the 1995 British Flat turf season.
