Out Sam led home a one-two for Gordon Elliott in the Paddy Power Cork Grand National.
The nine-year-old had been off the track since finishing third at Fairyhouse in early April and was a 13-2 second-favourite on his return to action in the hands of Davy Russell.
Russell rode a typically patient race, settling Out Sam in midfield for much of the three-and-a-half-mile journey before gradually easing him closer on the second circuit.
He was one of several horses still in with a chance rounding the home turn – and with the rail to help, he hit the front between the final two fences.
His stablemate Rogue Angel and Michael Hourigan’s The Gatechecker went in pursuit, but Out Sam held them at bay by a length and three-quarters and a neck respectively.
Elliott said: “I’m a bit surprised he won, although I thought he might run in the money.
“He’d been off a long time and I’d expect him to come on for the run.
“It’s great for the owners who are good supporters of the yard and Davy gave him a very good ride.”
Russell said: “I couldn’t believe how well he travelled. He had been frustrating last year – and to be honest, he’s just a different horse this year. Even going to the start, he was on the money today.
“He travelled and jumped everywhere. He had been so disappointing last year, I didn’t know whether to send him or sit – but he was full going to the second-last and had enough to get to the line.
“It was very important to win, and it’s also my first time winning this race.”
