Pretty Gorgeous impressed in the ARM Holding Debutante Stakes at the Curragh, as she gained her revenge on Shale to pick up Group Two honours.

Having been successful first time out at Bellewstown, the Joseph O'Brien-trained winner was second to his brother Donnacha’s Shale when they met at Leopardstown – but she put the record straight in some style on this occasion.

Still travelling sweetly for Shane Crosse with two furlongs to run, it came down to a brief tussle between the pair before the 3-1 winner asserted from the furlong pole and went to score by two and a half lengths from the favourite.

Mother Earth was the same distance back in third.

The Curragh race has a strong record of producing subsequent Group One winners, with Alpine Star being victorious 12 months ago, and the daughter of Lawman heads the early market for next year’s 1000 Guineas. 

O’Brien said: "She’s a very good filly. We were a bit worried about the ground, but she obviously handled it. Being by Lawman, we thought that gave her a chance.

"We felt that she’d definitely get closer to Donnacha’s filly after her run in Leopardstown, because we thought the Curragh would be more suitable for us.

"We were looking for an easy spot for her debut first time at Bellewstown, and she qualified for that race, but as it turned out, it actually was quite a good race."

Looking to future plans, O’Brien added: "The Moyglare looks the logical next step. She has proven she’s versatile ground-wise.

"I thought Shane gave her a lovely, cool ride today. It was a lovely, confident ride.

"She’s a big, strong lady. She cost a good few quid as a yearling, but she was an outstanding physical specimen at the sales.

"The sky is the limit for her."

Mac Swiney (28-1) returned to form for a shock victory in the Galileo Irish EBF Futurity Stakes.

Jim Bolger's juvenile had managed only ninth of 10 in this month’s Tyros Stakes at Leopardstown, having previously looked a youngster going places when he beat the well-regarded Wembley in a maiden over this course and distance.

The return to the Curragh did the trick, as Mac Swiney belied his starting price to pounce late as both he and favourite Cadillac surged past Ontario on either side of the long-time leader.

Mac Swiney showed the greater stamina to beat Jessica Harrington’s Cadillac by half a length, with the same distance back to Ontario in third.

He was winning a race which has been dominated by Aidan O’Brien since Bolger and Manning last won the Group Two affair five years ago.

The same trainer-and-jockey partnership were also on the mark with Mac Swiney’s sire, and subsequent Epsom Derby winner New Approach, back in 2007.

Bolger’s daughter, Una Manning, wife of the winning jockey, said: "We’re delighted with that run.

"He did it well on (soft) ground he wouldn’t really appreciate."

A return to the Curragh and move up to Group One level is now in the offing, with connections hoping Mac Swiney can continue to follow his sire’s path.

Manning added: "The plan now is to go for the National Stakes. When he won here the last time (dad) thought he was his Derby horse.

"We’re very pleased with him, he was very good. It seemed to be a strong race today.

"Hopefully we can get a good result in the National Stakes now, and go from there."

Elsewhere on the card, Make A Challenge (9-4) outclassed his rivals to win the ARM Holding Curragh Sprint Stakes with ease.

Denis Hogan's course specialist took his winning tally to five at the Curragh, sitting off the pace initially but challenging inside the last two furlongs and then storming clear under Joe Doyle.

The winner never needed to come under serious pressure and had four lengths to spare at the line from Downforce, with Schroders Mistake a neck further back in third. 

Make A Challenge, previously second to A’Ali in the Sapphire Stakes at the Curragh, has more high-profile targets in his sights after this six-furlong Listed success.

Hogan said: "That was impressive. I wasn’t expecting that, to be honest. I was expecting Speak In Colours to give us a right test and probably beat us.

"I thought we were always better over five, but that is his ground. There aren’t too many horses that would live with him on that ground, he just motors through it.

"This was only a stepping stone to the Flying Five here on Champions Weekend."
