Frankie Dettori rode the Aidan O'Brien-trained St Mark's Basilica to victory in the Dewhurst Stakes at Newmarket.
Stablemate Wembley was second, ridden by Ryan Moore, followed by Thunder Moon under jockey Declan McDonogh.
It is a seventh Dewhurst Stakes victory for trainer O'Brien, while Dettori has ridden two of the past three winners.
"I am pleased to be on the winner and he didn't put a foot wrong. He did everything he was asked to," Dettori said.
