Gavin Cromwell tasted victory with his first ever runner at Royal Ascot on Wednesday.
Quick Suzy landed the Group Two Queen Mary Stakes under Gary Carroll, with the success coming just under three months after the Co Meath trainer won the Stayers' Hurdle at the Cheltenham Festival with Flooring Porter.
Sent off at 8-1, the filly stuck to the inside rail to reel in American raider Twilight Gleaming, who was the eventual runner-up when 9-4 favourite, with Cheerupsleepyjean third at 50-1.
Cromwell said: “It’s absolutely unbelievable.
“It’s such an occasion, to have a winner is just fantastic.

“I was very confident she was going to run a big race, but where she lay with the English horses and the American horses – we didn’t know.
“I’m not known as a trainer of two-year-olds or sprinters so it’s very hard to tell, but I knew she was in great nick.”
