Paul Carberry rode a peach of a race to land the Coral Welsh National at Chepstow on the Michael Scudamore-trained Monbeg Dude.
Settled at the back of the field, the 10-1 shot crept into contention on the final circuit but still had plenty to do coming down the straight in the marathon contest as the jockey sat motionless.
Hot favourite Teaforthree was making the best of his way home under Tony McCoy, but Carberry timed his move to perfection and after challenging at the final fence, where Monbeg Dude wasn't foot-perfect, he got the better of a battle up the run-in by half a length. Triggerman stuck on for third.
The winning jockey said: "When I pulled him out early in the straight I knew I had a good chance. He's a bit lairy, and I didn't want to hit the front too soon, but he kept going to the line.
"I haven't had the opportunity to win this, so it was about time I took it. This is great. I thought we were going a bit slow, but the rest were off the bridle."
Scudamore, who is based 10 miles from the Welsh border and at one time dreamed of becoming an international rugby union player, said he hoped the victory would act as a testament to his team's ability to produce winners.
The handler, whose grandfather Michael won the race in 1957 and champion jockey father Peter took it four times when stable jockey to Martin Pipe, added: "We only knew on Thursday that Paul was going to ride him as that was when we heard Jamie Moore had to go to Sandown.
"There was a question of where we would go after he won at Cheltenham. My dad and all the owners wanted to come here, but I wanted to go back to Cheltenham on New Year's Day as I thought this might be too big an ask for the horse.
"It was an interesting discussion, but dad said we were going to the Welsh National, that there was only one place to go, and obviously I'm delighted we did.
"The horse has endured all sorts of problems with his shins and his knees and it's been a great effort from the vets that he's done this. But hopefully this real boost will show people we can do it as long as we get the right ammunition."
