Ut De Sivola gave odds-on backers a scare in the Visit Punchestown.com Juvenile Hurdle.
Willie Mullins' youngster figures prominently in the betting for the JCB Triumph Hurdle at Cheltenham and was sent off as the 1-4 favourite in the Grade Three contest.
However, Ruby Walsh was hard at work alongside Dermot Weld's Hisaabaat and Paul Townend at the final flight when that rival made a bad blunder.
The winning distance was three and a quarter lengths but before the mistake the race was still in the balance.
"His better jumping won it for him. He was very keen early on. I'm hoping he'll improve from that and we'll probably look to run him again on Hennessy day -- the experience will do him no harm," said Mullins.
Mullins' seven-race unbeaten run in bumpers also came to an end when Robin Angevin could only finish fourth behind odds-on favourite The Mighty Milan.
Ipsos Du Berlais (9/4) paid a nice compliment to Boston Bob when winning the Noel Farrelly Memorial Hurdle.
Five lengths behind Mullins' potential star in a Grade One at Navan, Noel Meade's grey looked in some trouble half a mile out as Western Leader stretched the field.
Walsh was next to send out distress signals on Mullins' new recruit Sergent Guib's, while China Rock, returning after injury, travelled nicely for a long way.
Rounding the turn for home Davy Russell got Ipsos Du Berlais into overdrive and he drew alongside Western Leader before pulling clear for a six-and-a-half length win.
"I was a little disappointed with the way he travelled through the race but he is lazy," said Meade.
"Davy said they went very fast, he's only a novice so I thought it was a very good performance. He'll get an entry for the three-mile novice hurdle (Albert Bartlett) at Cheltenham."
Paul Nolan's Carloswayback (11/4) returned to winning ways in the 49 Punchestown Hospitality Beginners Chase.
Meanwhile, Denis Hogan trained and rode Drive On Jim (8/1) to victory in the Racing UK Handicap Chase.
Joxer, (11/10f) saw off the unlucky Allure Of Illusion in the INH Stallion Owners EBF Maiden Hurdle.
