Al Riffa has a choice of engagements for his next outing, with Joseph O’Brien sure “the best is yet come” from his lightly-raced colt.

Winner of the National Stakes last season, the son of Wootton Bassett did not make his three-year-old return until the Curragh in July, finishing second to Mashhoor in the International Stakes.

He went from there to Deauville for the Prix Guillaume d’Ornano – and gave unbeaten French Derby winner and Arc favourite Ace Impact a real race in going down by just three-quarters of a length.

“He’ll either go to the Irish Champion or the Prix Niel, I’d say,” said O’Brien.

“He came out of his last run well. It was a great run, the winner is one of the best three-year-olds in Europe and we were right in the mix with him.

“Hopefully the best is yet to come with him.”

O’Brien also had news on his high-class filly Above The Curve, who has been placed in Group One company three times so far this campaign, most recently in the Prix Jean Romanet.

He said: “She may go back to France for the Prix Vermeille. She’s come out of the Prix Jean Romanet well.”

The exciting Al Riffa makes his eagerly-awaited return when he takes on four rivals in the Paddy Power International Stakes at the Curragh.

The son of Wootton Bassett stamped himself among the top juveniles in Ireland last season for Joseph O’Brien, winning the last two of his three starts, culminating in an authoritative success in the National Stakes at the Curragh.

That form was franked when Proud And Regal, trained by O’Brien’s brother Donnacha, subsequently took the Group One Criterium de Saint-Cloud.

A setback ruled out the long-time Irish 2,000 Guineas favourite from the first Irish Classic of the season, but now the Owning Mill handler hopes the colt can make up for lost time as he makes his three-year-old bow on his first run since September.

O’Brien said: “This is a nice race to start him back in. He has matured well from last year and we are looking forward to getting him started and hopefully it sets him up for a good season.”

He drops into Group Three company and steps up from seven furlongs to 10 for his first run, and O’Brien is not looking any further ahead than this weekend.

“We’ll take it one step at a time with him,” he added.

His opponents include Alfred Munnings, who has not run since finishing sixth in last season’s Chesham Stakes at Royal Ascot for O’Brien’s father, Aidan, last-time-out Limerick winner Layfayette, trained by Noel Meade, and Johnny Murtagh’s Mashoor, who is on a hat-trick after taking a Listed 12-furlong prize at the Curragh when last seen.

Aidan O’Brien’s Albany Stakes runner-up Matrika will be a warm order to go one better in the Group Two Airlie Stud Stakes.

The No Nay Never filly stuck to her task well when finding only Porta Fortuna too good in the 17-runner affair at Royal Ascot and Ryan Moore’s mount already has a verdict over Grand Job, whom she beat by three-quarters of a length on debut.

The pair lock horns again over the same six furlongs with just five other opponents to contend with.

Grand Job may lack for experience, but Joseph O’Brien is hopeful she can progress as he anticipates this summer.

He said: “She had a good run on debut over the course and distance and it would be great if we can get some black type with her. She is a nice Justify filly who is going the right way.”

Ante-post favourite Al Riffa will not run in in Saturday’s Irish 2,000 Guineas after suffering “a little setback” in training.

A son of Wootton Bassett, he made three starts last year for Joseph O’Brien, all at the Curragh, and signed off the campaign with a length-and-a-quarter success over Proud And Regal in the Group One National Stakes.

However, the Jassim Bin Al Attiyah-owned colt has not raced since September and while market leader for the mile Classic, he will be a notable absentee.

O’Brien said: “He has just had a little setback training. Hopefully it is nothing too serious and he will be back later in the summer.

“He has options at Ascot and further afield than that as well.

“These things happen, so it’s a long way from a problem. It is obviously disappointing for the owners. This race has been his target for the last while, but we will look forward to things later in the summer.

“Timing-wise Royal Ascot will be fine, but we will have to decide whether we want to run there or in other races. We’ll not be rushing into any decision.

“Everything else is good. We are looking forward to what is going to be a great weekend of racing at the Curragh. It is very competitive action and there’s much to look forward to.”

With Al Riffa missing the race, Qipco 2000 Guineas winner Chaldean heads the market.
