Wicklow Brave was a surprise winner of Betdaq Punchestown Champion Hurdle.
Champion trainer Willie Mullins sent five runners to post for the Grade One contest, although that number was reduced by one after Diakali was withdrawn at the start.
Of the remaining trio Wicklow Brave went off at 12-1, but took over the lead from Identity Thief in the back straight and never looked back under the trainer's son, Patrick.
My Tent Or Yours and the winner's stable companion Arctic Fire attempted to close the gap after the final flight, but Wicklow Brave was not for catching and Patrick Mullins punched the air as they passed the post a length and a half to the good.
Nicky Henderson's admirable veteran My Tent Or Yours was second yet again, with Arctic Fire's third-placed finish providing Mullins with a further boost in his battle with Gordon Elliott for the trainer's title.

The Elliott-trained Supreme Novices' Hurdle winner Labaik was back in action just three days after failing to start in the Herald Champion Novice Hurdle.
With Davy Russell taking over in the saddle from Jack Kennedy and a visor applied, he did consent to jump off, but never threatened to land a telling blow, passing the post a never-nearer fourth.
The Mullins first string, Vroum Vroum Mag, was well-beaten.
"Patrick winning this race means so much to me, the prize money was not what was on my mind," said the successful trainer.
"The horse took off and Patrick had enough sense not to fight him. He got the horse jumping well and they flew over the jumps.
"Turning in I thought that if Patrick could maintain it and not make any mistake then he had a right chance.
"Patrick started at the back but I think Wicklow Brave might have run away with him going down the hill. He won the Irish St Leger from the front and Patrick really got him jumping down the back. He pinged hurdles and was gaining lengths.
"I thought he was cooked after the second last but Patrick got a right good jump at the last. You could see Patrick eyeing up a big one and he hit him taking off. It was all or nothing."
