Silver Concorde came with a wet sail up the hill to claim the Weatherbys Champion Bumper at Cheltenham.
Robbie McNamara had the Dermot Weld-trained 16-1 shot not too far off a good pace set by Black Hercules and delayed his move until after the turn for home.
The six-year-old was always travelling well and quickened to the front when given the office by McNamara.
Silver Concorde bounded up the hill to beat the Willie Mullins-trained 7-2 favourite Shaneshill by a length and a half with Joshua Lane a length and three-quarters away in third.
"He did it well,” said Weld. “He's a very decent horse and I knew the drying ground would suit him well.
"Robbie's a master craftsman and rode a beautiful race. This horse has had his problems. He's taken time to come to himself as he was big and immature, but he's got there.
"He'll make a super hurdler, but there might be a few races to win with him on the Flat first."
McNamara praised the progress Silver Concorde had made this year, saying: "He's come back this year a bigger and stronger horse, coming here I thought if he stayed he would win.
"He picked up lovely in the straight. He won the last day on soft ground, but he's definitely better on a sounder surface.
"He's a good, athletic horse and there's no reason he wouldn't go over hurdles, he'll make a lovely dual-purpose horse."
