Pyledriver, bred for an outlay of just £5,000, took his earnings close to £2 million when returning from a year off to win at Royal Ascot.
He reduced his co-trainer William Muir to tears when he landed the £250,000 Hardwicke Stakes after 336 days off due to injury.
The six-year-old was nearly a doubt for Royal Ascot and his reappearance was billed as a pipe-opener for the King George VI and Queen Elizabeth Stakes, which he won last year.
