Whatuthink produced a tremendously game performance under Tom Doyle to inflict a shock defeat on Voler La Vedette in the Lismullen Hurdle at Navan.
Colm Murphy's top-class mare was a 1-7 favourite to claim this Grade Two prize for the second successive year and was ridden with extreme confidence by Andrew Lynch, settled right out the back of the field.
She made good headway on the turn for home to take much closer order and was within a couple of lengths of the front-running Whatuthink (25-1) jumping the second from home, but could not get any closer to Oliver McKiernan's charge and went down by four and a quarter lengths.
The winning trainer said: "He has always had ability. We decided to go back over hurdles with him. It was a great performance, but maybe fitness over the others was the key. He was tipping away all summer while the others were just starting out.
"He loves that ground and he kept going. He will go to Leopardstown now at Christmas and he might run before then. The plan was to make plenty of use of him and if they were good enough to go by him, so be it."
Paul Carberry rode a patient race on Noel Meade's 5-4 favourite Dylan Ross in the Irish Stallion Farms EBF Beginners Chase, picking off the opposition to lead on the run-in and beat Lake Windermere by a length and three-quarters.
The trainer said: "I asked Paul what the plan was and he said 'I'll be late!'. The last day was bit of a disappointment, but he was probably beaten by a very good horse (Jenari).
"He jumped well. He's very athletic. He's a real rubber ball and he was given the perfect ride. We'll stay at two miles. Paul thinks he wants better ground.
"He'll be entered for St Stephen's Day at Leopardstown. He mixed it with real good horses last year, so there's no reason why he shouldn't again if he jumps well."
Ted Walsh's Champagne James (15-8) made an impressive debut in the concluding bumper under a cool ride from Robbie McNamara.
