HEARTACHE produced a masterclass of raw speed to win the Queen Mary Stakes at Royal Ascot on Wednesday.

Clive Cox's two-year-old filly ripped past the always-prominent Happy Like A Fool inside the final 150 yards to score at odds of 5/1 under Adam Kirby.

American trainer Wesley Ward won the race in 2016 with Lady Aurelia, but this time had to be content with second place with 10/11 favourite Happy Like A Fool.

The runner-up did well to keep going, but she lacked the mesmerising zip of last season's winner and was two and a half lengths adrift at the line. Out Of The Flames finished third for the Richard Hannon team.

Kirby said: "She's good isn't she? She has loads of class. When she won first time out I knew she had loads of class but she's come on again from there.

"I'm delighted for Clive as he's a great trainer and doesn't get enough credit.

"There was no plan, Clive just said to go where I was happy but I was pleased to get in behind one. She's got a big future, she's very special."

Cox said: "That was very good and it means a lot to me. She's very special and she did it really well at Bath - I could not believe the time at Bath when they announced it. She's no different from the rest of mine in that they improve with their racing.

"We won a listed race with her mum (Place In My Heart), so this is very special, watching it with the owners as there's all manner of people here."

He added: "She's easy to train, she's got a good temperament but we're not quite sure how good she is. I was a bit worried when I saw the American filly as she looked pretty awesome walking around the paddock.

"Adam rode her with complete confidence and he's a pretty good fellow in the saddle. These are the stars of the future and she certainly is.

"We'll enjoy today as she could be that good and go for the Nunthorpe."

Ward said: "Ryan (Moore) said she was just beaten by a better filly and, watching, the race I agree.

"She broke as well as my others and she was there when he called on her, but the other filly had a little more.

"Hopefully, we can turn the tables as they are all young two-year-olds even though mine are forward. She's a big filly and will make up into something special.

"She'll go for the Molecomb and this just put her forward for that."

Hannon said of Out Of The Flames: "That was a super run, there's a big day in her one day and we'll have a look at the Prix Robert Papin or something like that."
