Quiet Reflection capped a fine day for Karl Burke with a brilliant performance in the 32Red Sprint Cup at Haydock Park.
The Commonwealth Cup winner travelled like the best throughout the six furlong contest and picked up impressively when asked to go and win her race.
The Tin Man emerged from the pack to give chase but could never get on terms with the three-year-old.
The front-running Suedois held on for third, some two and a half lengths adrift of the runner-up.
The delighted winning jockey, Dougie Costello said: "She's won as she liked, she's the real deal.
"I've never ridden anything like it and probably never will again. She's push-button go. She was fresh today and between the five and the three I was running away.
"I got there a little bit sooner than I'd liked."
Sky Bet cut the winner, who was completing a double on the card for Burke after Intense Tango's win in the feature handicap, to 5/1 from 10s for the Qipco Champions Sprint at Ascot next month.
The successful handler confirmed that race would be next saying: "She'll go to Ascot next for the Champions Sprint and I'm praying she stays well and sound so she can stay in training next year.
"I knew she'd improved and strengthened. She's such a straightforward filly.
"Jordan (Vaughan) does a brilliant job riding her, but I told him he had to go to Kempton to ride Georgian Bay and he's just got done a head in a 60 grand handicap.
"The whole team have done a great job and there's the farrier Andy Grant. He's done a fantastic job all year with her feet. They haven't been the best.
"I know we wanted a bit of rain but I was a bit worried when it got this soft as I thought it might play into the hands of the older horses.
"She's just got speed to burn. She travels well and is so relaxed. She blows when she works but when she runs she doesn't turn a hair."
Former jump jockey Costello still cannot believe his luck at riding such a talented horse.
"I've been lucky enough to get a big one in the bag," he added.
"She's such a simple filly to ride. It was almost like a good piece of work. It will be interesting next year when she gets stronger. She's a filly you only come across once.
"Jordan looks after her at home. I'm not allowed to ride her. I'm sure he'll get a chance on her at some stage.
"Whatever happens now, I'm just enjoying it."
James Fanshawe was delighted with the performance of slowly-away The Tin Man, who is set for a rematch with Quiet Reflection at Ascot.
The Newmarket trainer said: "He ran really well. Obviously we were concerned about the ground, but he's run with great credit. He'll go to Ascot now."
David O'Meara will probably send Suedois abroad in search of picking up a big prize.
He said: "I'm really happy with him to be placed in another Group One. He's very consistent and very tough. We'll give him a little break and look for something abroad at the back-end."
Dancing Star, who had been supplemented for this race, will be put away for the year after failing to handle the soft ground.
Trainer Andrew Balding said of the Stewards' Cup winner: "Franny (Norton) said she travelled well but when he let her down she struggled in the ground, so he looked after her.
"We'll put her away for next year. We'll start at a realistic level and work from there."
