Frankie Dettori opened his account at Royal Ascot when cruising home on Grandera in the Prince of Wales's Stakes to give owners Godolphin and trainer Saeed bin Suroor their third successive win in the Group One contest.
The four-year-old, a 4-1 shot, romped clear of the opposition in the final furlong to score by five lengths from Indian Creek (25-1) with the 7-2 favourite Banks Hill three-quarters of a length further back in third.
Godolphin's pacemaker Sydenham set a strong gallop and held the lead until the turn for home where there was some scrimmaging in behind. Banks Hill and Nayef made their bids for glory inside the final quarter mile but Dettori had them covered and as soon as he asked Grandera for his effort the race was over.
"We've found the key to him now - fast ground and a strong pace. We put a pacemaker in there just to make sure it was a strong pace and he had everybody beaten," a thrilled Dettori told the BBC.
"I bided my time because he's got a good turn of foot. He idles in front but the race was over by then. He's very tricky, he sweats and kicks - a bit of a playboy - but his ability is spot on.
"We've tried visors on him, we've tried all sorts but now the horse has come good, we've realised what he wants and he's going to be around for a long time."
Racing manager Simon Crisford said: "It was unbelievable I must say. "We were pretty scared when we saw Frankie taking a pull two-out because to win here that impressively you've got to be some sort of a machine.
"But this horse is still improving. He was a very good horse last year and loves fast ground."
