Trainer Willie Mullins enjoyed a pair of shock victories in the day’s other Grade One contests.
In the Champion Novice Hurdle, 18-1 shot Irancy headed up a one-two-three-four for Mullins.
Cheltenham winner Kopek Des Bordes had been the heavy favourite in the race but finished fourth, with Irancy winning by nine lengths ahead of stablemates Salvator Mundi and Karbau.
“Irancy has always been a good horse and met with a setback after winning here earlier in the season, but it might have been the best thing to have happened as he came here fresh,” Mullins told RTE.
“I gave Kopek Des Bordes a nice break after Cheltenham and probably gave him too much and should have brought him to somewhere like Ayr or Perth.
“Looking at him in the parade ring, I thought he was carrying too much condition and that showed at today’s pace.”
Mullins, having trained five of the eight runners, also enjoyed a one-two in the Champion Novice Chase.
Champ Kiely (22-1) took the lead at the penultimate fence before winning by six and a half lengths from 11-8 favourite Ballyburn.
On Wednesday, Galopin Des Champs will be the main attraction as he aims for a first Punchestown Gold Cup.
