Big Orange stunned reigning champion Order Of St George, in an epic running of the Ascot Gold Cup.
Michael Bell’s six-year-old led as they hit the home straight, and powered home strongest in a battle with the former winner to win by the narrowest of margins.
The Irish raider challenged late but was marginally touched off in one of the most thrilling finishes to the Gold Cup in recent years.
It’s the globetrotter’s first top-level victory after winning various pattern prizes including the Goodwood Cup and Prince Of Wales’ stakes.
“He’s just absolute superstar,” said trainer Michael Bell.
“He gives his all and he’s got a heart as big as himself.
“I can’t praise his attitude enough; he wants to race and he’s a colossal racehorse.”
