Sioux Nation returned to his best when defying a Group 1 penalty in the Goffs Lacken Stakes at Naas on Sunday.

Winner of last season’s Phoenix Stakes, the Aidan O’Brien-trained colt displayed his class as he dismissed the opposition in this Group 3 contest.

Sioux Nation (15/8 favourite) showed he had come on for his run at Navan last month on his first start for 204 days with a dominant performance, to score by a length and a quarter from stable companion Fleet Review in the hands of Ryan Moore.

Victory provided Moore and O’Brien with a treble after scoring with Broadway and Sergei Prokofiev earlier on the card.

Sioux Nation won the Coventry Stakes at Royal Ascot in 2017 and could return there next month for the Commonwealth Cup or the King’s Stand Stakes.

O’Brien said: “We came here to find out if it was five or six furlongs at Ascot.

“Seamus (Heffernan on Fleet Review) let his lad roll along to make it a good, strong six because we always felt he had a lot of speed and wanted to know whether we would go for the King’s Stand or the Commonwealth Cup.

“Ryan said he has all the speed in the world and he would have no problem going back to five, but maybe let him take on the three-year-olds this year (Commonwealth Cup). He also said he would be looking forward to the Nunthorpe.

‘He’s a great traveller and he quickens. It couldn’t be fast enough for him. Fast ground and fast horse – that is usually the way.”

Earlier on the card, the two-year-old colt Sergei Prokofiev had little trouble landing the odds in the Coolmore War Command Rochestown Stakes for the same connections.

Aidan O’Brien’s exciting youngster was close to the lead in third place as Mick Channon’s British raider Izzer set the pace.

The 2/7 favourite hit the front under Ryan Moore and soon put the race to bed. Andre Amar made late gains to take the runner-up spot, with Offline third and Izzer weakening into fourth.

O'Brien suggested the winner, who like Sioux Nation is a son of the unstoppable Scat Daddy, could either stay at five furlongs for the Norfolk Stakes or step up to six for the Coventry at Royal Ascot.

HARRINGTON DOUBLE

While O'Brien and Moore ended the day with three winners, trainer Jessica Harrington came away with a double.

She saddled a 1-2 in the six-furlong listed race for two-year-old filles as 10/1 shot Servalan ran out a length and a quarter winner from stable companion Chicas Amigas (9/1). The 4/9 favourite So Perfect had to settle for fourth after a troubled passage though the winner won on merit.

The Harrington-trained Brother Bear got back on track when taking listed honours in the Owenstown Stud Stakes.

Since winning at this level nearly 12 months ago at the Curragh, the colt had been out of luck, including when a close fourth in the Coventry Stakes at Royal Ascot.

Brother Bear (5/2 favourite) had shaped well when third over course and distance three weeks ago, after a 211-day break, and reaped the benefit of that outing by running out a length-and-a-half winner over Riyazan in the hands of Colm O’Donoghue.

Harrington said: “It’s great to get him back on track. He had a good run here and that’s the first time he’s really had good to firm ground since last summer. He definitely appreciates it.

“He might go to (Royal) Ascot for the Jersey. I’m not sure he’d get a mile at this stage – he might do later in his life. I think that is the logical step to go.”

The Co Kildare trainer was completing a quick across-the-card treble after Jetez went in at Limerick.

The final two races on the Naas card were cancelled due to fears over slippery conditions on the home turn following rain.
