Jet Setting inflicted a shock defeat on Minding in the Tattersalls Irish 1,000 Guineas at the Curragh.

The Aidan O’Brien-trained Minding was a red-hot 4-11 favourite following her runaway victory in the 1000 Guineas at Newmarket three weeks ago.

Jet Setting (9-1), trained by Adrian Keatley, was back in ninth at Newmarket, but emphatically reversed the form under Shane Foley to claim Classic glory by a head, with Now Or Never 10 lengths back in third.

The winner was supplemented for the race on Monday at a cost of €30,000.

“It’s a dream come true,” said Foley. “She’s a tough little filly and the ground came right for her – she ran a blinder at Newmarket but it was too fast for her

“Soft ground and a stiff mile was ideal for her.”

Minding was originally scheduled to bypass the Curragh and head straight to the Oaks at Epsom, but was drafted in at the last minute after stable companion Ballydoyle, the runner-up at Newmarket, returned unsatisfactory blood tests on Friday.

Everything appeared to be going according to plan for the three-times Group One winner for much of the contest, with stable companion Pretty Perfect and Jet Setting giving her a nice lead into the straight.

However, Jet Setting found another gear passing the four-furlong marker and it was soon obvious Minding would have her work cut out to reel her in.

Ryan Moore went for everything inside the final furlong and Minding responded to set up a grandstand finish.

The pair had raced clear of the field as the post loomed large and while Minding appeared to be getting the better of the argument at one stage, Jet Setting would not be denied.

Jet Setting holds an entry in the Coronation Stakes at Royal Ascot, but Keatley is keen to assess conditions in Berkshire before making a firm commitment.

He said: “It’s a dream. I was just hoping at the finish that she stayed where she was. I’m delighted for the owners and everyone in the yard.

“Hopefully this will help us get bigger, better and more competitive so we don’t have to keep going to Ayr every Monday!

“I don’t know what’s next. I didn’t look beyond this. She’s entered in Ascot but whether she goes or not I don’t know.

“When the rain was forecast we said we’d have a go here and, luckily enough for the lads, it worked out as it was a big call to supplement her again.

“She did something similar to what she did in Leopardstown (when successful in a Guineas trial). She likes being in front and having daylight around her.

“She probably wouldn’t go to Ascot if it was very fast but if there was a bit of ease she might. We’ll consider it and have a look.

“If she’s that good at a mile why would we try and change anything?”

O’Brien revealed Minding had suffered a minor injury, but could still head to Epsom.

“She hit her head on the stalls before they opened and burst her sinus. Ryan said she anticipated it before the gates opened,” said the trainer.

“Obviously we’re disappointed she got beat, and obviously it (hitting her head) wasn’t an advantage, but she ran well. The poor thing will have a headache, any way.

“We won’t take away from the other filly, though. It’s good for Adrian. The winner is a good filly and was very well trained by Adrian. She handles soft ground well.

“We’ll see how she is after that. She had two bits of work to do this week. After Ballydoyle came out the plan was to let her go here and then kick on.

“She’ll get an easy week now and if she’s well she could go to Epsom.”

Fascinating Rock reversed recent form with Found to claim top honours in the Tattersalls Gold Cup.

The Dermot Weld-trained Fascinating Rock had beaten O’Brien’s subsequent Breeders’ Cup Turf heroine in last season’s Champion Stakes at Ascot, but Found gained her revenge when the pair met in the Mooresbridge Stakes three weeks ago.

Found was the 8-15 favourite to confirm that form in this Group One contest, but Weld’s inmate showed improvement from his first run of the year and galloped on strongly to score by three and three-quarter lengths in the hands of Pat Smullen

Success Days, who split Found and Fascinating Rock when runner-up in the Mooresbridge, finished a close third, having raced alone against the stands’ rail in the straight.

Smullen said: “He’s a very good horse. We were always confident he was going to improve for his last run.

“We were very pleased with his work heading into the race.

“He’s a horse who is only maturing now, but he’s a horse who needs ease in the ground.

“We prayed for rain and got it.”

Weld said: “It’s a race I love to win. It’s an excellent Group One and it always takes a very good horse to win it.

“I’ve been fortunate to win it with a few very good horses in the past and he’s as good as any of them.

“He beat Found fair and square in the English Champion Stakes last year so there was no reason he couldn’t beat her again.

“I’ll speak to the owner but he might have the summer off now. We’ll look to train him for the Irish Champion Stakes and the Arc.

“His next race will most likely be the Royal Whip (Curragh in August) as a prep for the Irish Champion Stakes.

“He has all the class to win an Arc. He has won a group race over a mile and a half at Leopardstown so gets the trip well.

“He’s a big horse and takes a run, no matter what you do with him.

“Last year we took him to Windsor and he came back and won at Leopardstown. It’s hard to get him 100 per cent first time out.

“That was a excellent renewal of the race and Found is an outstanding mare.”
