One of three horses running in the green and gold silks of McManus, who was celebrating his 75th birthday, the Padraig Roche-trained grey was a 10-1 chance under Mark Walsh.
The former Flat performer made light work of the 22-runner contest, strolling home ahead of Winston Junior to emulate his half-brother Brazil’s success in 2022 for the same owner, trainer and jockey combination.
McManus said: “We’ve always had a lot of fun and great days here. It’s a place which means so much to so many and I’m delighted to see this one win for Padraig.
“Every winner is special and I go back a long time with Padraig’s father Christy. We won this race with Brazil a few years ago and they were praying the ground would be fast and every day it was drying out was a bonus.
“I’ve had winners here on my birthday before, but you never get tired of it.”
Roche added: “It’s near enough the same route we took with Brazil and we’ve always thought this race would suit him.
“Getting nice horses is half the battle in this game and I’m delighted Frank (Berry, racing manager) and JP decided to buy him.
“Today really mattered, but I’m sure we’ll find out down the road if he’s a bit better than a handicapper.”
McManus had more to celebrate in the very next race as he scored a one-two via Johnnywho (18-1) and Jagwar in the Trustmarque Ultima Handicap Chase.
Johnnywho, who is trained by Jonjo and AJ O’Neill, just managed to sidestep Search For Glory after he unseated his rider at the last before reeling in the front-running Quebecois on the run to the line.
He then had to dig deep for jockey Richie McLernon with 3-1 favourite Jagwar delivering a last-gasp challenge, holding on by a head.
It was a first Festival winner for AJ O’Neill since joining his father on the licence at Jackdaws Castle, and he said: “That was fantastic, Richie gave him an unbelievable ride.
“He’s threatened to land a big one on a couple of occasions. He obviously went close in the Kim Muir last year and it’s great to come back and go one better.
“When I saw Jagwar coming I was just hoping we could keep our nose in front and luckily we were able to do that.”
