Bullards Alley was a shock 50-1 winner of the Pattison Canadian International Stakes at Woodbine racecourse on Sunday night, meaning Aidan O'Brien's wait to equal the world record for number of Grade/Group One wins in a year goes on.
The mark of 25 set by the late Bobby Frankel has long been threatened by O'Brien, who reached 23 victories in 2001 and 2008.
A Dewhurst Stakes 1-2-3-4 at Newmarket on Saturday led by US Navy Flag had put him one away from joining American great Frankel, and with Ryan Moore doing the steering, the four-year-old Idaho was well fancied to improve on his eighth place in the Prix de l'Arc de Triomphe.
But the unheralded Bullards Alley, trained by Tim Glyshaw, did not read the script, coming off the home turn full of running and rocketing clear when asked the question by jockey Eurico Rosa Da Silva.
To his credit, Idaho stayed on down the straight to make late ground in fourth, just ahead of last year's winner Erupt, but in the final reckoning there was only one horse that mattered.
O'Brien and Moore were also unsuccessful with their other runner on the card, as Rain Goddess trailed home last in the E.P. Taylor Stakes won by the Andrew Balding-trained Blond Me.
