Alcohol Free prevailed in a tight finish for the Group One Juddmonte Cheveley Park Stakes at Newmarket.
Andrew Balding's filly was less exposed than most of her rivals in the six-furlong prize, but Oisin Murphy gave her a positive ride.
The champion jockey was happy to take up the running from favourite Miss Amulet at half way and she was there to be shot at running up the hill.
The previously unbeaten Dandalla moved into contention briefly, but her challenge petered away and it was Richard Fahey’s Umm Kulthum, a winner at Ayr last weekend, and Ken Condon’s Miss Amulet who gave Alcohol Free the most to do.
Despite having just the third run of her life, Alcohol Free showed a willing attitude and while Umm Kulthum challenged on her far side and Miss Amulet on her inside, Alcohol Free, a sustained late gamble, won by half a length and a head.
The winner was given a 20-1 quote for next year’s 1000 Guineas by Betfair.
Alcohol Free had finished second behind Happy Romance last time out, but turned that form around with Richard Hannon’s filly who was only fourth this time.
🤩 A thrilling race!

"She didn’t have a great draw at Salisbury and she showed a bit of inexperience and we knew she would come on for that," said Balding.
"At the end of the day, Happy Romance was likely to be one of the favourites and we only had a couple of lengths to find on her. We had the option to run in the Rockfel, but Jeff (Smith, owner) was keen on going for the Group One and he was dead right.
"She has been on a fast track really, as she only started faster work about three weeks before she ran and we went to the races not knowing quite what to expect as she was the first two-year-old filly we had run.
"She won very easily there (Newbury) and the next logical step was to go for the Dick Poole and she showed enough there to warrant coming here.
"She should stay (a mile) I would have thought. She relaxes well. She acts better with a bit of cover. Oisin was intent that he couldn’t see any pace in the race and he didn’t want to be too far back.
"I’m well past giving him instructions. He did a fantastic job. Just for the yard, it is fantastic, as Jeff has been with us a long time, with dad (Ian Balding) and he has been a big supporter of ours, so it is great to get him a Group One winner again.
"She won’t run again this year. We will see how she does in the spring and we will make a decision nearer the time (whether she runs in a trial). She is obviously good enough to go (to the Guineas), so we don’t need to go to a trial to find out – it’s just whether she would benefit for a run in the spring."

New Mandate continued his rapid rise through the ranks with victory in the Juddmonte Royal Lodge Stakes.
The Ralph Beckett-trained two-year-old made it a hat-trick of wins for the season as he successfully stepped up to a mile in the Group Two prize.
Having demonstrated his battling abilities when squeezing through a tight gap to land a Listed race at Doncaster last time out, the New Bay gelding was forced to dig deep again before emerging victorious under Frankie Dettori.
Despite Ontario throwing down a late challenge, he could not find a way past New Mandate with three-quarters of a length separating the pair at the post.
Beckett said: "I was always surprised he could do it at seven really, given his pedigree and so on. It is extraordinary I managed to get him beaten twice in maidens. The first time out I hadn't done enough with him really and I suddenly realised that afterwards.
"The second time, Jack Mitchell kind of got rolling a bit early on the July Course. He has shown up from the first piece of fast work he did. Everything he has done has been very professional.
"He was gelded in January as he was like Warren Beatty on steroids. We had to geld him, but he wouldn’t have been the horse he is if we hadn’t."
A trip to America could be on the cards for New Mandate, with Beckett eyeing the Breeders’ Cup Juvenile Turf, for which he was introduced at 10-1 by Paddy
Beckett said: "We will see where we go from here. Obviously he can’t run in anything worthwhile in the spring, so we have to cut our cloth this autumn.
"We will have a discussion about the Bredeers’ Cup Juvenile Turf. It has been great."
🥇 Supremacy reigns supreme

A fabulous couple of days for Clive Cox and Adam Kirby gets better as Supremacy lands the Group One @JuddmonteFarms Middle Park 👏 pic.twitter.com/hzvk76aTod
Supremacy led his rivals a merry dance and held off Lucky Vega to win the Juddmonte Middle Park Stakes.
Clive Cox's youngster had impressed in the Richmond Stakes last time out, but the quality of the race was so deep that Supremacy was sent off a 13-2 chance.
Given a strong wind at the track, Adam Kirby employed the same prominent tactics as he had done when winning the Rockfel Stakes on stablemate Isabella Giles 24 hours earlier and Supremacy was never really headed.
His task was made slightly easier by halfway when Frankie Dettori’s saddle slipped on the keen-going Method and he had to call it a day before the race began in earnest.
Shane Foley was eager not to give the leader too much rope on favourite Lucky Vega, but Minzaal was dropped right out at the back and ended up making up plenty of ground into third.
Supremacy was not for catching, though, prevailing by half a length, with Minzaal beaten a further two and a quarter lengths.
Saffron Beach landed something of a gamble when making a winning debut in the Blandford Bloodstock Maiden Fillies’ Stakes.
Available at long odds on Friday, the Jane Chapple-Hyam-trained New Bay filly, who returned at 12-1, knew exactly what was required on her racecourse bow, running out a four-and-a-quarter-length winner of the seven-furlong prize.
Chapple-Hyam said: "It’s no surprise. We were very happy with her and she had been galloping with the colts Albadri and Prince Of Abington. She has shown a nice attitude. It’s always nice to see her go away from the field.
"It was impressive and it is nice to have a good class filly in the stable.
"I certainly did back her. Prince Of Abington won nicely at Ascot and Albadri ran a blinder the other day in the Tattersalls Stakes. When you’ve got horses working together, you get a guideline."
A step up in class is now likely for Saffron Beach with the Racing TV Stakes, better known as the Radley, at Newbury identified as a possible target.
Chapple-Hyam added: "I think I’d like to keep her at that trip on her next start. The Sangster and Wigan families are local to Newbury, though I wouldn’t want soft ground for her. We will just have to watch this weird English weather."
