Hugo Palmer’s Mootasadir took the step up to Pattern company from handicaps in his stride as he landed the Group Three honours in the Recruit Island Diamond Stakes at Dundalk.
The three-year-old led home a one-two for Newmarket trainers with Global Giant, trained by Ed Dunlop, filling the runner-up spot.
Pat Cosgrave delivered the Dansili colt with a strong challenge in the final furlong to beat his fellow UK raider by a length and a half.
Massif Central made the early running from his Michael Halford stablemate Kalaxana with the 6-4 favourite Ming close up.
The complexion of the extended mile and a quarter contest changed as Mootasadir (4-1) gained the upper hand to lift the spoils.
Cosgrave said: “I rode my first ever winner here when it was a grass track. I’ve only had about five rides here and had three or four winners so it’s been a lucky track for me.
“He’s a strange horse as he’s had six runs in total winning four out of four on the all-weather and twice on the grass been tailed off.
“He just really needs an artificial surface for some reason. It was a good call by Hugo to step him up from a handicap into this Group 3.
“He’s a gorgeous looking individual, and I’m sure Hugo will find another nice race for him.”
Donnacha O’Brien had earlier reached a century of winners for the season with a narrow victory on the 6-5 favourite Lost Treasure in the Eilish McAllister Race.
He said: “I’ve ridden 100 good horses for good trainers. I’m very grateful and very lucky to be riding some nice horses. That’s what has made it possible.”
The colt had look set for a comfortable victory but he put the breaks on close home and just held Geological by a nose.
“The one in front went off quick and I was left in no man’s land and I had to judge it myself. I gave him a squeeze and I got there too soon on him,” said the leading Irish rider.
“He stopped when he got there and I think he probably spooked at the light at the winning line as well.
“When the horse in front of you stops you kind of have to kick in case something comes from behind. He stops when he gets to the front, and he’s done that in most of his races.”
His father, Aidan O’Brien, was completing a double thanks to the victory earlier of Frosty, who showed she has inherited some of her full sister Winter’s ability when making a winning debut.
Winter won the English and Irish 1,000 Guineas in 2017 and Frosty got her career off to a flying start in the Irish Stallion Farms EBF Fillies Maiden.
Seamie Heffernan had her slotted in about fifth place as her stablemate Credenza, the 7-4 favourite, made the running until into the straight.
Fancy Feat, who was lying second, took up the running but Frosty (9-1) got the hang of things to storm past and score by a length.
