Buckaroo booked a potential Irish 2,000 Guineas challenge as he got back to winning ways with a stylish victory in the Coolmore Arizona Irish EBF Tetrarch Stakes at the Curragh.

Beaten only a short head on his reappearance in the Group Three Ballysax Stakes, the drop back to a mile worked the oracle in this Listed event as the son of Fastnet Rock cruised stylishly into contention approaching the two-furlong pole and quickly put the race to bed when Shane Crosse pushed the button inside the final furlong.

The Joseph O'Brien-trained 15-8 favourite was pushed out for a cosy four-length success from Navan scorer Wexford Native and New Energy, who faded into third having attempted to make all.

The winner - who runs in the colours of Qatar Racing - is now likely to stay at a mile and was shortened to 14-1 from 33-1 with Betfair for the St James's Palace Stakes at Royal Ascot. Before that is likely to be a return to the Curragh later this month.

O'Brien said: "I was really happy with that. I took a bit of a chance coming back to a mile, but I thought he'd been working with plenty of pace, maybe more than I was giving him credit for in his earlier days.

"He looks like an Irish Guineas horse.

"He's a big, strong, powerful horse and has quite a laid-back attitude. I discussed it with Sheikh Fahad and we decided to come here and find out if he was a Guineas horse.

"I see him as more of an eight to 10-furlong horse than a 10 to 12-furlong horse. He seems to be versatile ground-wise."

Earlier Aidan O'Brien's Blackbeard needed every yard to come on top in a thrilling finish to the Listed GAIN First Flier Stakes.

Cork winner Crispy Cat attempted to make all in the hands of Leigh Roche for Michael O'Callaghan and refused to lie down when challenged by the eventual winner throughout the closing stages of the five-furlong contest.

However, it was the Ballydoyle colt, sent off the 11-10 favourite, who had his head in front when it mattered most, responding gamely to Ryan Moore's urgings and showing a most willing attitude to make it two from two.

The son of No Nay Never won in good style at Dundalk on debut and having continued his education here, looks to have booked his ticket to Royal Ascot, for which he was given quotes of 8-1 for the Norfolk Stakes over the minimum trip by Coral.

O'Brien said: "The ground is softer than we thought it was going to be, but he did well to battle back.

"He'll go on to Ascot for one of the races over five or six. Ryan said he could get six.

"If you can get a couple of runs before Ascot in this country you are very lucky. There are not that many races."Thriller! 😱
