Lisnagar Oscar caused a 50-1 upset as reigning champion Paisley Park disappointed in the Paddy Power Stayers' Hurdle at Cheltenham.
Making smooth progress on the near side, Lisnager Oscar hit the front before the final flight in the hands of Adam Wedge, to put trainer Rebecca Curtis back in the big time.
Lisnagar Oscar galloped on strongly up the hill to hold the challenge of Ronald Pump (20-1) by two lengths, with Bacardys (33-1) a further three lengths away in third place.
Apple's Jade had set a decent gallop and opened up a big led until she came back to the field after the third-last flight.
The runners bunched up, with several horses in with a chance two out, but it was Lisnagar Oscar who proved strongest to claim the coveted prize.
Last year's winner Paisley Park looked to be in trouble some way out and faded to finish seventh.
Speaking after the race the winning jockey Adam Wedge said: "Unbelievable. This is fantastic. My horse tried its heart out. It fought like a lion out there."
Owner Rebecca Curtis added: "I thought 50-1 was a massive price. I am delighted for Adam, he gave a brilliant ride there."
Earlier in the day Samcro won the Marsh Novices' Chase, Sire Du Berlais was triumphant in the Handicap Hurdle and Min won the Ryanair Chase, while there is still the Stable Plate Handicap Chase, the Novices' Hurdle and Amateur Riders' Handicap Chase to take place.
