Sizing Europe waltzed to victory as his prohibitive odds suggested he would in the Clonmel Oil Chase.
Henry de Bromhead's multiple Grade One winner was sent off at 1-7 in the Grade Two contest against four rivals and he never looked in any serious bother.
Rathlin set out to make most of the running in the second colours of owners Gigginstown House Stud, with Magnanimity, in the first-choice silks, settled in behind.
Andrew Lynch was happy to keep the 2011 Queen Mother Champion Chase winner in third in the early stages but Lynch soon moved him up to track the leader.
Tranquil Sea, who has won the last two renewals of the race, was in the field but he could never land a serious blow.
Having pulled Sizing Europe out at Down Royal because of heavy ground, the ground was once again testing, but the two-and-a-half-mile trip did not stretch him as much.
The class act took up the running halfway down the back straight and put 15 lengths between himself and his pursuers in no time to cross the line well clear of Magnanimity.
Lynch told At The Races: "He was unreal. Early on we went a good gallop and he grabbed a hold of the bit and half took off.
"He settled passing the stands but then down the back he took off again.
"The more you pull him, the more he wants to go, but he was very good - he was running away with me most of the way.
"That was two and a half miles and he galloped all the way to the line, but you wouldn't be afraid of dropping back to two miles."
De Bromhead said: "Wow - that's all I can say.
"I say it every time, but I'm so lucky to have him and he nearly seems to be getting better and was brilliant there.
"Andrew said he was running away with him at times coming down the hill.
"I'm the same as Alan (Potts, owner) - I'd love to see him on good ground over three miles.
"I know he is a way better horse on better ground and I don't want to see him in a slog.
"His next run is ground dependent but he'll have three entries at Christmas - the King George, the Lexus and the Paddy Power Dial-A-Bet.
"I'm ruling the Tingle Creek out.
"The King George is a race that Alan would love to have a go at and we'll have to give it serious consideration.
"This season he is jumping so much better at the slower pace."
A potential star of the future was on show in the shape of Tarla, who made a sparkling fencing debut in the T.A. Morris Memorial Mares Chase.
In receipt of weight from nearly all of her rivals, Ruby Walsh decided not to hang about on Willie Mullins' six-year-old.
Sent off the 11-8 favourite on the back of some smart hurdles form, she was nevertheless thrown in at the deep end in this Grade Three event.
It was hard to tell Tarla was making her first start over fences, however, as she jumped like an old hand.
Main market rival Knockfierna was badly hampered by the fall of Ros Brin half a mile out, but she would have had her work cut out in any case as Tarla defeated Our Girl Salley by eight lengths without coming off the bridle.
Mullins said: "She was very good and she had looked a natural at home.
"When she won over hurdles at Punchestown it looked as though fences would be no problem.
"We schooled her then and she looked as good as she was out there.
"She is very quick, even when she was a little wrong at a fence. We'll mix it between hurdles and fences now.
"There is a bit more prize-money over fences. Trying to keep her sound will be the hard thing.
"She was off the track for two years so the worry is to see if she's sound in the morning.
"The Grade One at Punchestown is her end-of-season target."
Oliver McKiernan sprung a surprise when Whatuthink landed the Lismullen Hurdle at Navan on Sunday and the same colours were back in the winner's enclosure when Quietly Fancied took the Clonmel Oil Service Staion Handicap Hurdle.
Ruby Walsh was always prominent on the eight-year-old (11-2), who shook off several challengers and ran on strongly when tackled by Harold's Cross at the final flight to win by half a length.
The absence of Lord Of Lords appeared to have gifted the INH Stallion Owners EBF Maiden Hurdle to 1-4 favourite The Paparrazi Kid, but Dushybeag (7-1) was sent into a big lead by Adrian Heskin and Michael Hourigan's five-year-old kept on to win by 21 lengths.
Christy Roche's Code Of The West (9-1) travelled best into the straight in the Prior Park Service Station Clonmel Handicap Chase and had it sewn up at the last under Jody McGarvey before winning by a length and three-quarters.
