Archie Watson has vowed to supplement Duty First for the 1000 Guineas at Newmarket following her empathic triumph in the Group 3 Dubai Duty Free Stakes (Fred Darling) at Newbury on Saturday.

Archie Watson's three-year-old filly took the step up to the next level in her stride when running out a commanding three and a half-length winner of what seemed to be a competitive Dubai Duty Free Stakes.

Despite having filled the runner-up spot in the Prestige Fillies' Stakes at Goodwood and finishing third behind the Aidan O'Brien-trained Bubbling in the Dubai Rockfel Stakes at Newmarket in September, Duty First found herself a 33/1 chance on her seasonal reappearance in the 1000 Guineas trial.

Having raced towards the near side under Hollie Doyle, who famously sported the colours to success with Watson's stable star Bradsell, Duty First picked up smartly once switched to the centre of the track.

Down on the stands' side rail, Harry Eustace's Time For Sandals looked to be travelling smoothly into contention, while Hey Boo was in their pitching with a furlong to travel, but neither could match the finishing kick of Duty First, who effortlessly put her rivals to the sword in the closing stages.

Whilst the daughter of Showcasing isn't currently entered in the opening fillies' Classic at Newmarket in May, trainer Archie Watson has no doubt that she will be supplemented on the back of what he viewed as an impressive performance.

"I don't know if I was taken by surprise, and I guess probably as it looked a very strong Fred Darling and you had proper Group horses in there," said Watson.

"The way she has won it has probably surprised me, but the fact she has come and done something like that hasn't really, as she has been in great order this spring.

"She can definitely go to a mile in the Guineas; she's not in the English Guineas but I think that's where she will run – she was actually scheduled to go to the Italian Guineas, but I don't think that will happen now.

"I imagine after a performance like that she will go to Newmarket.

"She was still very raw when she ran in the Rockfel last year, and I don't think the undulations on the Rowley Mile will bother her; she's also been round Goodwood and ran well there, so I'm happy. A Classic horse is what we all want."

Doyle added: "She's hit the line hard, and I think she will improve for the step up to a mile. We're not overly surprised, as her work at home has been good, and we've always thought highly of her.

"She probably wasn't quite where she needed to be last year and yet achieved more than she should have, so hopefully this is her year."

The runner-up, Hey Boo, also looks set for a trip to Newmarket according to trainer Jack Channon, who was over the moon with his filly after she outran odds of 40/1.

Channon said: "Our filly is still a big baby and George (Bass) said she travelled really sweet and he thought he had the winner covered, but she has just quickened very smartly and our filly just didn't quite know what she was doing.

"Two runs on the all-weather is no real preparation for this type of race really, but you saw her class and potential at the end, and a mile will see her in a lot better light – I wouldn't swap her.

"She goes straight to the Guineas; she's a high-class filly, and I think she deserves her place there."

Whilst the front pair look destined for the 1000 Guineas, Harry Eustace was quick to admit they will revert to sprinting with Time For Sandals

Eustace concluded: "I think we're allowed to think about the Commonwealth Cup, and her form is solid. It's a race where fillies have done well in, funny enough, the few that have run in it, so we'll think about that, and we'll just have to see how she trains.

"She'll get an entry for it. That stiff six at Ascot could be ideal, but she's a filly who could be a lot of fun."
