The five-year-old mare won a two-mile Listed race at Newmarket last autumn and took third spot over the same distance in an Ascot Group 3 last month.

She remains in Group 3 company for her visit to the Knavesmire this weekend but is eased back in trip to a mile and three quarters.

Jockey George Downing is reunited with Miss Alpilles for the first time in almost a year – and the pair will face six rivals in the £100,000 contest.

Lambourn-based Walker said: “She is in great order. I was really happy with her run at Ascot.

“It’s probably not ideal coming back in trip, I think she stays very well. But I think this is as good an opportunity as she’ll get to try and bag a Group race.

“George Downing knows her very well and it’s a good opportunity for him – he’s a big part of our team.

“He played a big part in helping to get this filly just to relax, switch off and be able to stay these trips, so it’s great to give him a chance. The quicker the ground the better.”

Miss Alpilles is likely to be prominent in the market, which looks sure to be headed by the John and Thady Gosden-trained Danielle, who runs for the first time since winning a Listed race at Doncaster last autumn.

Saturday’s seven-race card also features the Class 2 William Hill Epic Boost Handicap. The five-furlong speed test is worth £65,000 and has attracted 21 runners.

Newmarket trainer Stuart Williams is hoping speedster King Of Light can go one better than his promising second-place effort at Goodwood on 1 May. The four-year-old gelding is drawn in stall seven and will be ridden by Sean Kirrane.

Williams said: “We’re very much looking forward to running King Of Light at York.

“I was very happy with his comeback run – I think he’s a progressive horse.

“He’s come out of that Goodwood race really well.

“A big field and a sprint handicap, it’s going to be very competitive. But we’re happy with the draw, have got a good jockey booked and I’m very hopeful for a good run.”

Saturday’s first race action is at 1.30pm with the William Hill Keep Your Raceday Positive Handicap.
