Sumo Sam backed up her Goodwood stroll with a gutsy display in the Betfred Park Hill Fillies’ Stakes at Doncaster.

The three-year-old made virtually all as a 25-1 chance in the Lillie Langtry Stakes last month, thriving on very testing conditions to come home an eight-and-a-half-length winner.

The bookmakers made her the 4-1 joint-favourite on Town Moor and Rossa Ryan was not allowed anywhere near as much rope as Tom Marquand was permitted at Goodwood.

She did hold a three-length advantage turning into the straight but looked a sitting duck as eventual third Lmay and runner-up One Evening put down strong challenges.

They could not quite get by Sumo Sam, though, as she prevailed by a length and a half in the colours carried to victory by Snurge in the 1990 St Leger for the Paul Cole stable, who now shares his licence with his son, Oliver.

Betfair trimmed the winner to 10-1 from 16s for the Fillies & Mares race at Ascot on Champions Day.

Oliver Cole said: “She got a bit lonely out in front and then dug deep. She’s a very classy filly and very, very tough and very, very game.

“It was seriously impressive, wasn’t it? Two furlongs out you thought she might fall in a hole, but she was ultra-fit and in very good form and very fresh.

“That (soft) ground seems to be important to her. It’s not as soft as it was at Goodwood, but nothing much is.

“She’s potentially a Cup horse for the future. A couple of furlongs out you thought she was beaten and she pulled it out – it’s pretty incredible what she’s done. I’m taken aback really for words.”

Regarding the future, he added: “She could potentially (go to Ascot), or there’s the Prix de Royallieu in France. She’s entered in that and you normally get soft ground, so that’s a definite possibility.”

Sumo Sam bids to follow up her runaway success at the Qatar Goodwood Festival in the Betfred Park Hill Fillies’ Stakes at Doncaster on Thursday.

Paul and Oliver Cole’s filly was a widely unconsidered 25-1 shot for the Group Two Lillie Langtry Stakes, having been beaten in her first five outings of the season, but devoured the testing conditions on her way to an eight-and-a-half-length victory.

With the ground set to be on the easy side once more, Oliver Cole is hopeful of another bold showing in the ‘fillies’ St Leger’ on Town Moor.

He said: “She’s in good form, obviously she needs a bit of cut in the ground but it’s looking like she’ll get that and she’s pretty fresh after her last race at Goodwood. We’re looking forward to it.

“We were definitely expecting her to run better on that ground (at Goodwood), she is a very good filly and all being well she’ll go to the Prix Royallieu after this. The more rain the better for her.”

Sumo Sam’s rivals include Aidan O’Brien’s Irish raider Boogie Woogie, David Simcock’s Ching Shih, who was last seen chasing home St Leger candidate Arrest in the Geoffrey Freer at Newbury, and the William Haggas-trained pair of Golden Lyra and Crack Of Light.

Assessing the chance of his duo, Haggas told Sky Sports Racing: “Crack Of Light has basically been running in France this year and has won a Listed race and is Group Two placed and Group Three placed.

“She’ll run a good race. It’s her first time at a mile and six and I’m not so sure about that, and Mr Oppenheimer (owner) isn’t either, but we came to the conclusion that we’ve got little to lose by trying and quite a bit to gain.

“Tom (Marquand) has plumped for Golden Lyra, who was useful last year at the backend on soft ground. She should relish the step up in trip and she ran a much better race in France last time, her best race for a year, staying on all the way to the line.

“I think she’ll run a good race Golden Lyra, especially now the rain has come. I think it was the rain that swayed Tom to go her way.”

Boogie Woogie will be ridden by Ryan Moore, who told Betfair: “This is another difficult race to call, but Boogie Woogie had good form in deep ground earlier in the season, including in Group One company, and hopefully you will see a sharper, better filly than you did at Cork off a break last time.

“This longer trip is well worth a go, and she has the form to figure prominently if she stays.”

John and Thady Gosden also fire a twin assault, with One Evening and Lmay both declared, while Night Sparkle is stepped up in class on her first start for Andrew Balding after winning her last four races for Michael O’Callaghan.

Tom Marquand excelled from the front at Goodwood as Sumo Sam ran her rivals ragged to win the Qatar Lillie Langtry Stakes.

Having stolen a decisive advantage on Quickthorn in the Group One Goodwood Cup earlier in the week, Marquand was again allowed to do his own thing on a stayer.

He bounced straight into an early lead on Paul and Oliver Cole’s filly, and in a race run in very testing conditions, he never looked like being caught at any stage.

Frankie Dettori briefly looked a threat on Free Wind who moved into contention on the bridle, however, as soon as Dettori asked his mount for an effort, she floundered in the heavy ground.

Sumo Sam (25-1) was allowed to come home unchallenged, with River Of Stars staying on from the rear to claim second, some eight and a half lengths away, with a further five and a half lengths back to Time Lock in third.

Marquand was a late jockey booking and Oliver Cole said: “Tom’s given her a brilliant ride and she’s a very good filly.

“Out in front like that, she was not going to be pegged back. It’s great for the old man and Sir Martyn (Arbib) as they have been together so long.

“I’m not sure what we’ll do next, she’d have a penalty in the Park Hill. She’s got the class to run in a Cup race but she’s got to have her conditions.”

Cole added: “We’ve done a lot of stalls work with her since her last run – she’s gone in twice a week. In her last two races she’s been left and that hasn’t been helpful. She takes a lot of pushing in and a lot of cajoling, and the stalls handlers make it look so easy. We’re always standing a few lengths behind because we don’t want to get booted!

“Full credit to the team at home, and thanks very much to the guys at the stalls who are the unsung heroes. They do what a lot of us wouldn’t do, so full credit to them. Also to the boys who have ridden her in the stalls at home, because I know I wouldn’t ride her.

“I was as confident as you can be with the ground because you never know how they will go through it, but she’s gone through it like a really, really good horse. Someone said to me a few weeks ago if you want to get the best out of that horse leave her until next year, so this just shows you have to persist with horses. They are not there to be decorations.”

Marquand was thrilled to secure a winning ride and said: “I’d be lying if I said I did any research into the race.

“I came back in from the last race and they said ‘can you do 8st 11lb?’ so I jumped aboard. I’ve seen plenty of her and was due to ride her on the day I got kicked at the Guineas weekend. I watched her go and finish second and it looked like she wanted a trip.

“Mr Cole and Olly were keen to go and make it a solid test, and as the other day showed if you find a rhythm in front it’s a hard track to get horses back. She’s done well, and while she was getting tired in the last half furlong the damage was already done.”
