Monty's Pass stormed to a convincing win in the world-famous steeplechase at Aintree.
The mount of Barry Geraghty raced to a 12-length victory from Supreme Glory with trainer Ginger McCain's Amberleigh House back in third.
Gunner Welburn was fourth with Montifault fifth and last year's winner Bindaree in sixth.
Only 14 of the 40 horses finished the gruelling four-and-a-half mile course in Liverpool.
The 7-1 favourite Shotgun Willy was pulled up at Becher's Brook the second time around by jockey Ruby Walsh, winner of the day's first three races.
"It's the thing you dream about. To have the winner is unreal," said Monty's Pass' Irish trainer Jimmy Mangan.

"He's had a good rest and has come back 100 per cent. He has never let us
down and is always in the money. He's the star of the stable.
"Barry [Geraghty] was superb."
Another pre-race fancy Ad Hoc unseated jockey Paul Carberry at the 19th fence, while Youlneverwalkalone was pulled up at the 12th and champion jockey Tony McCoy pulled up Iris Bleu at The Chair.
Geraghty was delighted with his horse's ability to cope over the big Aintree fences.
"He was like a cat, he jumped unbelievable," said Geraghty, who was the leading jockey at this year's Cheltenham Festival.

"I had a lovely run. There was no traffic up front.
"It's a thrill to finish a National never mind to win one.
"It's hard to believe he could win so easily."
Tremallt took up the early running from Montifault with Gunner Welburn, Chives, Blowing Wind and Torduff Express all featuring near the front in the first half of the race.
At The Chair on the second time around Gunner Welburn took the lead but made a mistake shortly after to let Montifault back in.
Carbury Cross also made a showing after the water jump as Monty's Pass moved to join the leaders for the first time.
Gunner Welburn was first over Becher's Brook on the second circuit ahead of Monty's Pass, Behrajan and Carbury Cross.
Following the Foinavon fence, the field was strung out with Gunner Welburn leading and only a handful of horses still in contention.
With two fences left, Monty's Pass went clear from Amberleigh House and a tiring Gunner Welburn.
Monty's Pass safely cleared the last and powered home, while Supreme Glory made a surging run behind to overhaul two horses to get up for second.
Nine horses were pulled up, while eight unseated their riders, eight fell and one refused.
One of the fallers, Goguenard, had to be put down after coming to grief on the second circuit.
Gerry Supple broke a leg when Burlu fell while Alan Dempsey fractured a wrist after taking a tumble from Robbo.
In addition, Timmy Murphy was concussed and broke his nose when unseated by Torduff Express while Bramblehill Duke's jockey Brian Crowley broke his collarbone.
With so many well-fancied horses failing to finish, it was a good day for the bookmakers.
However William Hill were landed with paying out more than £400,000 on two winning bets alone, their worst hit in Grand National history.
