Mimikyu bids to open her account for the season in the Sky Bet Lester Piggott Stakes at Haydock.

The daughter of Dubawi saw off the reopposing Time Lock to land a novice event over this course and distance 12 months ago and went on to win a Newmarket handicap and the Group Two Park Hill Stakes at Doncaster before the end of her three-year-old campaign.

She was narrowly beaten by River Of Stars in the Bronte Cup at York a fortnight ago and joint-trainer Thady Gosden is expecting her to take a step forward in a race his father John and owner George Strawbridge won in 2016 with Mimikyu’s sister and subsequent Group One heroine Journey.

He said: “She ran a very nice race first time out this year in the Bronte when just denied.

“She’s come out of that well. She’s obviously dropping back down in trip two furlongs at Haydock and she’s got the hood off, which will help we think.

“It was fast ground at York last time and she’s won on soft, so she’s not ground dependent, and Haydock is a nice, even track for her.”

Following her neck defeat to Mimikyu at Haydock in June last year, Time Lock went on to push fellow Juddmonte-owned filly Haskoy close in the Galtres Stakes at York.

The winner went on to go close in the St Leger and won a Group Three on her recent reappearance, while Time Lock again finished second on her comeback in a Listed race at Goodwood.

Juddmonte’s racing manager Barry Mahon is hoping for a sound surface on Merseyside to give Time Lock the best chance of running up to her best.

He said: “Hopefully we get good to firm ground as we want proper summer ground for her, so hopefully there’ll be no over-watering going on.

“I think she’s going to develop into a good filly this year. She’s a big, scopey filly and hopefully she could develop into a very good filly.”

Roger Varian switches Modaara to the turf following a 13-length victory on the all-weather at Kempton, while German hopes are carried by the Peter Schiergen-trained Nachtrose.

William Haggas won last year’s renewal with Sea La Rosa and would love to follow up in a race now named in honour of his legendary late father-in-law with Sea Silk Road.

Haggas said: “I think it is a great honour that officials at Haydock Park have named the race in memory of Lester. The family are absolutely thrilled.

“Haydock was the place where Lester had his first winner and rode his last winner so there is no more appropriate venue to have a race run in his memory.”

He added: “It would be lovely if Sea Silk Road could win on Saturday. She is a filly that has not yet won a Group race but she won a Listed race last year and was second in the Ribblesdale at Royal Ascot.

“First time out this year in the Middleton they went too slow for her over that extended mile and a quarter and she didn’t really relax.

“She has come forwards for that run though and going back to a mile and a half I think will suit her. We are hopeful she will go well.”

The field is completed by Poptronic, who finished third behind the Gosdens’ Free Wind in the Middleton Stakes and trainer Karl Burke feels she may have been underestimated in the market.

“She ran a good, solid race first time up and will improve for stepping up to the mile and a half. I think they’re making her the outsider of the field, but she’ll run a good race, she’s a good filly and she’s in good form,” said the Spigot Lodge handler.
