Anthony Honeyball's forward plan produced a thunderous finish at Kempton Park as they won the Coral Trophy.
The 8-year-old was part of the chasing pack on the home straight, with Al Dancer leading the three-mile chase.
But jockey Ben Godfrey made a perfectly timed charge in the home straight, giving him a 15-2 chance to win by a quarter of a length.
“This is the biggest win of my career. It takes a horse like this kid to run a race like that,” said trainer Godfrey.
“Having him compete in these highly competitive races is what you do it for and why you get out of bed every morning. I'm happy for the owners and for Anthony.”
Al Dancer, an outsider with 28 wins and 1 loss, took second place, and popular Bout Greatness, who had 4 wins and 1 loss, took third place.
Paul Nicholls said Aintree was a “potential” for Kalif du Berlay, who scored a hat-trick in the Coral Adonis Juvenile Hurdle.
The four-year-old saw off Give Me Five over the final hurdle, giving jockey Harry Cobden his 128th win and extending his lead at the top of the Jockey's Championship standings.
“He's been tough. I don't know if we rode him correctly or not, but he's a horse with a lot of promise and we're going to look after him. We're excited about that. Nichols said.
“I don't think he'll run for Triumph because he's had some tough races over there. I think Aintree is also a possibility if we're happy, but he's won three times so If we didn't run again, it wouldn't have happened.'' It's not the end of the world.
“We've liked him for a long time. He's got the size, the range, everything. For a big horse like him to win three races is impressive enough for a young horse. That’s it.”
