Rasmeyaa is set to take her chance in the Qipco 1000 Guineas at Newmarket on Sunday despite reservations that the race may come just a shade too soon.

Following a pleasing workout on Tuesday the Dermot Weld-trained filly was given the go-ahead to bid for Classic glory.

"Like everybody they've had a tricky spring. I think trainer and jockey both feel in a perfect world they'd have another 10 days just to get her to blossom, but we don't have that perfect world," said Angus Gold, racing manager to owner Sheikh Hamdan Al Maktoum.

"She worked well on Tuesday and they are perfectly happy to let her take her chance.

"She's got her whole season in front of her and I'm sure she'll be better for the run. We don't have the benefit of time on our side, but we'll give it a go."

Gold confirmed that Weld's stable jockey, Pat Smullen, will keep the ride on the filly, who won the second of her two starts in tremendous style at Leopardstown in October.

Weld left in Big Break at Monday's confirmation stage, but she is to wait for either the French or Irish versions, with the Etihad Airways-sponsored Classic at the Curragh on 26 May appearing the more likely destination.

"We're going to see. She just needs a little more time," said Teddy Grimthorpe, racing manager to owner Khalid Abullah.

"She has the option of the French Guineas. At this stage I would say the Irish Guineas would be a bit more likely."

Ante-post favourite Hot Snap will now be the owner's sole representative at Newmarket. The impressive Nell Gwyn Stakes winner is reported to be ready for the big day.

"She's fine and is in good shape," said Grimthorpe.

Winning Express was third behind Hot Snap in the Nell Gwyn, but her trainer Ed McMahon is to adopt different riding tactics in a bid to reverse the form.

"I probably got her as fit as I could, but we rode her to get the seven furlongs and we got into a bit of a squashing match about two out. She's come out of the race very well," he told At The Races.

"I think everything will be right for her on Sunday. The ground will suit, but I think it's an open Guineas.

"We're going to ride her slightly different. I won't give her the ground to make up."

Sheikh Hamdan's retained jockey in Britain, Paul Hanagan, looks like taking the mount on outsider Diaminda, who will be trainer Alan Jarvis's first ever runner in a Classic.

"She's my first runner in a Classic. I've had some good horses before and never entered them so that should tell you something," said the Twyford handler.

Harry Dunlop is happy for Roz to make her three-year-old debut in the big race.

That has been the plan since she finished second to Certify in the Shadwell Fillies' Mile over this course and distance in September.

"We've had a good winter with her. She had a day away for a racecourse gallop at Kempton. It's onwards and upwards, ready for Newmarket," said the Lambourn trainer.

"She loves fast ground and hopefully she should get that. There had been showers around and the ground didn't completely suit her when she ran in the Fillies' Mile there.

"Certify got a run on us and our filly was gaining at the end. We are realistic that we have to improve on the figures, but we have to give it a go."
