Death Duty gave Gordon Elliott and Gigginstown House Stud a clean sweep of Grade Ones at Fairyhouse on Sunday after registering his third straight victory over fences with a foot-perfect round in the Bar One Racing Drinmore Novice Chase.
The 8-11 favourite was partnered by Davy Russell and was too strong for Ratvinden in second.
Elliott, Gigginstown and Jack Kennedy had already won the Bar One-sponsored Royal Bond Novice Hurdle with Mengli Khan and Apple's Jade secured back-to-back wins in the Hatton's Grace Hurdle.

It was the first time in history that any trainer secured all three Grade 1 prizes on offer on the day.
Elliott said: "This is what it's all about. To train three Grade One winners in one day is unbelievable, it's something you dream about.
"Fairyhouse is one of my local tracks and it seems to be lucky for me. All the lads are here from the yard and my father is here and they'll all be delighted."
Of Death Duty, he added: "I might have been getting it wrong with him last year, saying he needed three miles. Davy said there today he's loads of speed. He's won another Grade One for us and we'll enjoy today and see what happens.
"He wouldn't be an Arkle horse, more JLT (Novices' Chase). To be fair he travelled over to Cheltenham last year and wasn't right and got very light over there. I probably shouldn't have run the horse, but thankfully he came back and showed how good he is today.
"Whether we go to Cheltenham or don't go to Cheltenham, I'll put the horses in the races they can win."
Paying tribute to Elliott, Russell said: "We talk about Willie (Mullins) and Willie is so good, he puts the benchmark so high for these trainers.
"I suppose Gordon is one reaching up for that mark. He's a fantastic trainer and a great man to ride for.
"Willie is an exceptional man, but today is Gordon's day and Gordon is the up and coming youth of the game, which is great to see. I'm on the way out and he's on the way in!"
Apple's Jade produced a brilliant front-running display to successfully defend her Bar One Hatton's Grace Hurdle crown.
The Gigginstown House Stud-owned mare claimed her first victory after joining Elliott when seeing off former stablemate Vroum Vroum Mag in a thrilling renewal 12 months ago and was the even-money favourite to strike Grade One gold for the sixth time in her career.
Jack Kennedy sent the five-year-old straight to the lead, with Willie Mullins-trained Stayers' Hurdle hero Nichols Canyon always her closest pursuer as he went in search of a ninth win at the top level under Paul Townend.
The pair rounded the home turn almost as one, but Apple's Jade soon stamped her authority on the contest, pulling right away between the final two flights and safely negotiated the last to cap a hugely impressive performance.

Elliott soon quashed any notion his star mare could run in the Champion Hurdle, stressing the OLBG Mares' Hurdle - for which she was cut to 6-4 favourite from 5-2 with RaceBets - would be the target in March.
He said: "She looked class, to be honest. We thought she was a lot stronger at home. She's like a bull and Jack gave her a great ride.
"I was always taught to win the race you can win, so the mares' race will be the one I'll go for, all being well.
"She's only five years of age and she's six Grade Ones won. She's a different mare at home this than she was last year.
"The way she kept pulling it out, you'd have to be nothing but impressed with her."

Earlier, Mengli Khan further enhanced his growing reputation with victory in the Bar One Racing Royal Bond Novice Hurdle at Fairyhouse.
Formerly trained on the Flat by Hugo Palmer in Newmarket, the imposing four-year-old suffered defeat on his first two starts over hurdles for Elliott last season, but had raised his game this autumn to claim successive wins at Navan.
He was a heavily-backed even-money favourite to provide his trainer with his first success in this Grade One event and, after travelling strongly into contention under Jack Kennedy, he hit the front jumping the second flight from the finish.
Early Doors did his best to make a race of it, but Mengli Khan was much too strong in the end, passing the post with five and a half lengths in hand. Early Doors was in turn a long way clear of the remainder.
Kennedy said: "In his last couple of races he wasn't really settling, but he's such a big horse with a long stride, he just needed a good gallop. We got it today and he's done it very well.
"He's such a big horse it's hard to believe he ran on the Flat as a two-year-old, but he seems to have it anyway. He's a top-class horse."
Espoir D'Allen maintained his unbeaten record with an assured display in the Bar One Racing Juvenile Hurdle at Fairyhouse.
Snapped up by leading owner JP McManus after winning a French bumper, the three-year-old was visually impressive on his first two starts over hurdles for Gavin Cromwell at Punchestown and Down Royal.
The son of Voix Du Nord was the 8-13 favourite stepped up to Grade Three level and while Barry Geraghty was initially happy to sit at the rear of the five-strong field, he took much closer order racing down the back straight and was in front rounding the home turn.
Elliott's dual winner Mitchouka did his best to cover the move and appeared to be travelling equally as well approaching the second flight from the finish, but Espoir D'Allen jumped it much the better and careered away to score comfortably in the end by four and a half lengths.
Davids Charm (10-1) claimed top honours in the Bar One Racing Handicap Hurdle.
The John Joe Walsh-trained six-year-old lined up in the 100,000 euro contest in fine form having won successive races at Listowel and Galway before returning to Listowel to finish second in September.
He was a 10-1 shot for this fiercely competitive contest under Rachael Blackmore and while he was untidy at the final two flights in the home straight, he had enough in hand to hold Meri Devie at bay. Yaha Fizz and She's A Star dead-heated for third.
