Oisin Murphy has been booked to partner Via Sistina after trainer George Boughey confirmed the Qipco Champion Stakes as the intended target for his star mare at Ascot on Saturday.

A brilliant winner of the Group Two Dahlia Stakes at Newmarket in the spring, the daughter of Fastnet Rock subsequently secured Group One glory in the Pretty Polly in Ireland and has since been placed in the Falmouth Stakes and beaten a nose in the Prix Jean Romanet in France.

Connections decided against contesting the Prix de l’Opera on Arc weekend due to the prevailing fast ground and have a choice of engagements this weekend, with Via Sistina also holding an entry in the British Champions Fillies & Mares Stakes over a mile and a half.

But with rain forecast to hit the Berkshire track, Boughey is planning on running his five-year-old against the boys on British Champions Day – and with regular rider Jamie Spencer in Australia to ride Simon and Ed Crisford’s West Wind Blows in the Caulfield Cup, three-time champion jockey Murphy has been called up.

Boughey said: “It (Champion Stakes) looks very much the plan at the moment. Ten furlongs I think is her optimum trip and it looks like the ground might be in her favour.

“The forecast for France looked like it was going to dry up ahead of the Prix de l’Opera and it certainly did. Steve and Becky Hillen (owners), and fair play to them, they wanted to wait for Ascot and thankfully the rain looks like it’s coming.

“There’s a chance the race may be held on the inner loop and there could be 50 per cent more runners in the fillies’ and mares’ race, so it could get messy. I think the Champion looks the right spot for her.

“The more time she has between her runs, the better she is as well. I still think her best performance of the year was on very soft ground at Newmarket, having had a long break through the winter.

“She’s very fit and very fresh and ready to rock and roll.”

Via Sistina is set to lead a small but select Boughey team into battle at Ascot, with Believing an intended runner in the Qipco British Champions Sprint and Baradar and Raadobarg both set to contest the concluding Balmoral Handicap.

Of the latter pair, Boughey added: “The trip is a bit of a question mark for Baradar – William (Buick) will need to be very patient on him, I think. He has a good record on the horse and knows him well.

“He won well the last day and he seems to have found another leg for the cheekpieces. We know he handles very soft ground, he won the International at Ascot earlier in the season and he comes here in as good a shape as I’ve had him all year, but it’s going to be a long final furlong for him, I’d say.

“Raadobarg takes his racing very well and seems to have come out of his run in the Darley Stakes the other day (finished third) in super shape.

“He deserves his place in the line-up. He’s a big price, but arguably he might be one of the classier horses in the race and we know he handles the ground.”

Via Sistina will head straight for the Prix de l’Opera on Arc weekend following her narrow defeat at Deauville.

So impressive when winning the Group Two Dahlia Stakes at Newmarket in the spring, George Boughey’s star mare subsequently struck Group One gold in the Pretty Polly Stakes at the Curragh.

The five-year-old was out of luck when dropped back from 10 furlongs to a mile in last month’s Falmouth Stakes at Newmarket, but looked set to double her top-level tally on her return to a mile and a quarter in the Prix Jean Romanet, only to be denied in the final stride by Andre Fabre’s Mqse De Sevigne.

While frustrated by the nose defeat, Boughey was delighted with Via Sistina’s performance and is now targeting a return to France on the first Sunday in October.

“We were obviously delighted to see her produce what was arguably another career-best really,” he said.

“The Fabre filly looks progressive and I think we were arguably unlucky in defeat. She was in front a long time as we just wanted to have a clear run at it.

“I think we’ll go straight to the Opera on Arc day and I think we’ll probably ride her with a little bit more patience. We’re always learning in this game and I think just holding on to her a bit longer and using that wicked turn of foot over that trip will suit.

“The Opera has been a long-term target for a long time. The Romanet was the immediate target and is possibly the one that got away, but we’re very proud of her.

“She’s finished first, second and third in three Group Ones this year, having won a Group Two beforehand, so she’s been a real star for us.”

Three weeks after the Prix de l’Opera, Via Sistina could make an appearance on Qipco Champions Day at Ascot, where she is doubly engaged.

She could take on the colts in the Qipco Champion Stakes or step up to a mile and a half for the British Champions Fillies And Mares Stakes.

Boughey is in no rush to nail his colours to either mast at this stage, adding: “Hopefully we’ve got another run or possibly two if she turns up on Champions Day. I think it would be very exciting to see her run on very soft ground as it usually is at Ascot.

“We’ve put her in the Champion Stakes and the Fillies And Mares and I know we ran her over a mile in the Falmouth, but if it did look the right spot for her, I would be interested to see her dropped out stone cold last over a mile and a half on soft ground and waited with.

“She’s by Fastnet Rock out of a Galileo mare, so there’s a chance she might stay, and the fillies’ division would look notably weaker than the Champion Stakes.”

Via Sistina will seek to add to her growing trophy cabinet when she returns to 10 furlongs in the Sumbe Prix Jean Romanet at Deauville.

The four-year-old has developed into a star performer since joining Newmarket handler George Boughey from Joseph Tuite and is yet to finish out of the money in three starts this term.

A Rowley Mile romp on her seasonal bow in the Dahlia Stakes signalled a move to the highest level for the Pretty Polly Stakes and she passed that Curragh test with flying colours to secure a first Group One triumph.

Her progress was halted slightly when only third to an on-song Nashwa over a mile in the Falmouth Stakes, but Via Sistina’s handler is confident she can regain the winning thread on Sunday, as she moves back up in distance on the Normandy coast.

Boughey said: “It’s the last four-year-old and above fillies’ only race this year and it has kind of been the race for her for some time really. She goes there in good shape.

“She had a little break after the Falmouth and I slightly regret running her back over a mile in hindsight. She’s a filly who hit the line really well in the Pretty Polly and arguably might get further, but she was an even-money shot and it was definitely worth a go.

“She added another bit of Group One black type to her pedigree and I think you will see the real Via Sistina back up at 10 furlongs.”

British raiders have a good record in the contest and Via Sistina is joined in the line-up by Hughie Morrison’s One For Bobby, who tasted victory on French Soil at Vichy most recently.

Having secured Group Three honours with that Grand Prix de Vichy triumph, the Summerdown trainer believes she has earned a shot at this valuable prize.

“We’re just going to the next stage and we thought she deserved a crack at this,” said Morrison.

“It was a toss-up whether we would run Stay Alert as well, but it poured with rain (on Friday morning) so that put paid to that and we pulled out at the last moment.

“One For Bobby enjoys the softer ground, but I don’t think it was soft when she won at Vichy. She enjoyed it at Nottingham definitely, but she’s been on the go a fair while and with these fillies you just hope they are still firing.”

Joseph O’Brien’s Above The Curve will bid for her third win on French soil and the consistent filly arrives having chased home Al Husn in the Nassau Stakes at Goodwood, while Jessica Harrington’s Trevaunance will also make the trip from Ireland.

The home challenge is led by Andre Fabre’s Mqse De Sevigne, who brings Group One course form to the table after making a successful drop back to a mile in the Prix Rothschild last month.

Francis-Henri Graffard’s Darkaniya accounted for the Fabre contender when they clashed in the Prix de la Pepiniere earlier in the campaign and now returns from a summer break looking to secure her third-straight victory.

Fabrice Chappet’s Plesant Jane and Henk Grewe’s German challenger Valpolicella are also engaged.

George Boughey will walk the track before deciding whether to let Via Sistina take her chance in the Tattersalls Falmouth Stakes at Newmarket on Friday.

The improving five-year-old broke her Group One duck last time out over 10 furlongs in the Pretty Polly at the Curragh.

She is due to drop back down to a mile on the July course but Boughey says there must be enough ease in the ground to enable her to show her best.

“We will work as if she is running but she needs the rain for her to run,” he said.

“The Falmouth has always been a plan for her as she does look very good on a straight track, but softer ground is key to her.

“There are lots of times she could run where she will get soft ground and we are not going to do anything that is not in the best interests of the horse.

“If it did rain, she will be very competitive. We will walk the track and if it is the same as Ireland last time I imagine she will take her chance, but if it is any faster she won’t.

“For her pedigree, if she was to win a Falmouth she would be pretty sexy.”

Via Sistina is one of nine declared for the one-mile Group One that headlines Friday’s action, with a stellar cast lining up on the July course.

Defending champion Prosperous Voyage is one of two for Ralph Beckett and is joined by Royal Ascot runner-up Remarquee, with the Coronation Stakes second making her first outing for new owners Wathnan Racing.

John and Thady Gosden are also double-handed as they saddle not only last year’s Prix de Diane winner Nashwa, but also the Juddmonte-owned Coppice.

The Sandringham scorer was partnered by Frankie Dettori when triumphing at the Royal meeting, but with the Italian serving a ban picked up at the summer’s big week, Tom Marquand picks up a rare Clarehaven ride and deputises aboard the progressive three-year-old.

Ed Walker’s Random Harvest is another to bring smart Royal Ascot form to the table, while Roger Varian’s Ameynah was last seen finishing sixth in last year’s 1000 Guineas and returns from 439-days off the track.

Pam Sly’s Astral Beau and Aidan O’Brien’s Never Ending Story complete the field.

George Boughey is optimistic Via Sistina can make a successful raid on Irish soil in the Yulong Pretty Polly Stakes at the Curragh.

The Classic-winning trainer has not yet saddled a winner in Ireland and to break his duck in a Group One would be quite a way to do it.

Boughey nominated this 10-furlong contest as a likely target following her hugely impressive display in a soft-ground Dahlia Stakes on the Rowley Mile in early May – and the Newmarket handler’s confidence will grow with every drop of rain that falls ahead of Saturday’s feature.

Boughey said: “She goes there in very good form, the rain overnight will help and any more will certainly help her chance again.

“I’ve never seen her look so well and she’s been training super, so it’s all systems go as long we get a little bit more rain.

“She’s gone very good since she won at Newmarket. It’s been a dry spring and a dry early summer, but she’ll be busy whenever she gets her preferred ground and it looks like she might get it this weekend.

“She’s travelled over good and she’s ready to rock and roll. It’s been the plan for a while and we look forward to taking them on.”

Joseph O’Brien has saddled two of the last four winners of the Pretty Polly in Iridessa (2019) and Thundering Nights (2021) and is this year doubly represented.

The clear first string is Above The Curve, who was last seen landing a Group Two in France, while Goldana steps up in trip after finishing fourth in the in the Lanwades Stud Stakes last month.

“We are looking forward to running them. They are both in good shape,” said O’Brien.

“Above The Curve won nicely in France last time and this race will suit her well.

“Goldana shaped the last day as though she will enjoy the extra couple of furlongs. Any rain that falls will be a help to her. She stayed on well last time.”

Aidan O’Brien sends Never Ending Story back into battle just under a fortnight after finishing second to the brilliant Blue Rose Cen in the Prix de Diane at Chantilly.

“Never Ending Story ran really well in France, that was her first time over a mile and a quarter,” said O’Brien.

“She came out of that race very well so that is why we are going back early with her. Hopefully she will run well.”

Paddy Twomey’s Rosscarbery bids to follow up victory in the Munster Oaks at Cork, with Insinuendo (Willie McCreery), Stay Alert (Hughie Morrison), Comhra (Jim Bolger) and Trevaunance (Jessica Harrington) completing the line-up.
