New trainer Charlie Appleby saddled his first winner for Godolphin when Expressly bolted up on her debut at Ascot.
The Street Cry filly (7-2) made light work of her seven rivals to score by four and a half lengths from Mu'ajiza (12-1) in the Ascot Lawyers Maiden Fillies' Stakes.
Snow Powder (14-1) was a further neck back in third.
Appleby, who was assistant to banned trainer Mahmood Al Zarooni, was only granted a licence to train 200 horses for Godolphin at Moulton Paddocks in Newmarket last week, after the BHA concluded he had "no awareness of the actions" of his former boss.
The 38-year-old, who has been with Godolphin for nearly 15 years, was not present to welcome in Mickael Barzalona's mount, who was equipped with a hood for her debut.
Barzalona said: "We went a nice pace and she got a good lead. She did everything very easily, but she is still very green. Charlie didn't want to take any chances with her so we applied the hood. It's is good for him, so well done Charlie.
"I'm sure he will have many more winners."
Connor Beasley is fast emerging as one of the top riders of his generation and having ridden out his 7lb claim on Monday, the 18-year-old enjoyed his 20th winner of the season on only his second ride at Ascot when Barnet Fair (10-1) got the better of Steps (7-2 joint-favourite) in the concluding SIS Live Handicap Stakes.
It earned plenty of praise from trainer Richard Guest, who said: "Connor's mother used to work for me and I was hoping to nab him as an apprentice but he went showjumping for a couple of years and Michael Dods got him.
"Nothing went right for him here on his penultimate start but Connor was on board at Hamilton last time and he didn't get any luck in running.
"My dad always said that the jockeys who win are the ones who make least mistakes - not that he made any mistakes up there - but he didn't get a clear run. Yet Connor was sensible, didn't even give him a crack and left this horse with plenty more in the tank. The way he rode him there left plenty for today, so it is all credit to him."
