Irish trainer Aidan O'Brien is today toasting his success after winning his sixth consecutive Irish Derby on Sunday.
Carlton House failed in his quest to land the Dubai Duty Free Irish Derby at the Curragh as Treasure Beach led home a Ballydoyle one-two-three.
The Queen's colt finished third in the Epsom Derby and was sent off the 5-4 favourite to go a few places better in Sunday's mile-and-a-half Classic.
Yet despite having travelled strongly early on, Michael Stoute's three-year-old faded into fourth.
Aidan O'Brien had already won eight Irish Derbys, so knew the terrain better than anyone.
But even the master Irish trainer could not have wished for a better outcome as Treasure Beach initiated the rout, with stablemates Seville and Memphis Tennessee filling the minor roles.
Treasure Beach was a 25-1 shot when beaten just a head by Pour Moi at Epsom, but showed that performance was no fluke to give Colm O'Donoghue his first Irish Derby success.
O'Brien said: "Memphis Tennessee set a nice, even pace and it seemed to suit all the horses.
"Colm was excellent on Treasure Beach and settled him beautifully before producing him brilliantly.
"Treasure Beach has progressed with every run and he has a few options now - he could go for the Grand Prix de Paris at Longchamp, the King George (Ascot), or else he could have a break before coming back for the second half of the season.
"We are very lucky in that his owners have decided to keep their horses in training as four-year-olds, and that gives us options with giving the three-year-olds breaks."
John Warren, racing manager for the Queen, said Carlton House ran "flat" and is likely to be dropped in distance to a mile and a quarter.
Richard Hannon's Lilbourne Lad continued his rise through the juvenile ranks with a gritty display in the Dubai Duty Free Railway Stakes earlier on the card.
Assistant trainer Richard Hannon jnr said: "Lilbourne Lad is a real star and we're very pleased.
"The last furlong looked like slow motion but Lilbourne kept pulling out a bit more.
"We'll either come back here for the National Stakes or go for the Prix Morny at Deauville next."
Invincible Ash (9-2) flew home to deny the British contingent in the Woodies DIY Sapphire Stakes, while O'Brien saddled a one-two in the Dubai Duty Free Double Millionaire EBF Maiden, with After just getting up to deny Taigan.
Pirateer (5-1) put the gloss on another dream day for the Ballydoyle operation by taking the Dubai Duty Free Full Of Surprises Celebration Stakes - O'Brien's second treble in as many days.
Midday, meanwhile, suffered a shock reverse when she was firmly put in her place by Epsom Oaks disappointment Misty For Me in the Stobart Ireland Pretty Polly Stakes at the Curragh on Saturday.
The Irish 1,000 Guineas winner bounced back with a super all-the-way win from Henry Cecil's multiple Group One scorer.
Seamie Heffernan soon had the O'Brien-trained filly dictating affairs and the 100-30 chance pulled right away to trot up six lengths from the 1-3 favourite, who in turn was four and a half lengths clear of Chrysanthemum.
O'Brien said: "It's very possible that she could go for the Irish Oaks now but we also have Wonder Of Wonders for that.
"Misty For Me would have no problem sticking at 10 furlongs and we'll have to go home and talk about it."
O'Brien and Heffernan were completing a double after David Livingston (2-1 favourite) was a comfortable three-length scorer in the Barronstown Stud EBF Maiden.
O'Brien then made it a treble when Freedom (5-2 joint-favourite) got the better of Forever Glory in the hands of his son, Joseph, in the Kilsaran International Maiden.
Many racegoers at Newcastle on Saturday would not have even been born when trainer Reg Hollinshead first took out a licence, but he showed he still has what it takes after Tominator landed a 25-1 surprise in the John Smith's Northumberland Plate.
The 87-year-old first started training in 1948 and while he was not at Newcastle to see the four-year-old win by a length and three-quarters, he was represented by his son, Andrew.
Mick Channon's Montaff chased him home, with Deauville Flyer third and Petara Bay fourth.
Last year's winner Overturn, running off a 13lb higher mark, finished a gallant sixth under jumps jockey Henry Brooke.
