Sweeney Tunes capitalised on a terrible mistake three out by 4-7 favourite Mikael D'Haguenet to lift the Woodlands Park 100 Club Nas Na Riogh Novice Chase at Naas.
The Willie Mullins-trained Mikael D'Haguenet looked to be going ominously well when his blunder took him from first to last in the Grade Two contest.
Davy Russell needed no further prompting on the Paul Nolan-trained Sweeney Tunes (3-1) and set sail for home, holding the challenge of Charlie's Vic, who came from the rear of the field, by three and a half lengths.
Mikael D'Haguenet, who had been completely stopped in his tracks, remarkably rallied to get third.
Nolan said: "It's nice to win these Grade Two races, but at the end of the day Mikael D'Haguenet looked like he would have sluiced in.
"He's entered in the Pulteney Land Investments Novices' Handicap Chase at Cheltenham, but he was given a mark over 140 so he's not eligible for that.
"He's in some of the open handicaps at Cheltenham, but running this close to the Festival is not ideal so we might look at the Irish National instead."
Russell doubled up when bossing the Paddy Power Mobile App Handicap Hurdle from the front on Tim Doyle's well-backed Mallowney (11-4), who cleared right away in the straight to score by seven lengths.
"He ran very well in the Boylesports Hurdle (at Leopardstown last month) and only for a mistake at the last he would have been placed," said Doyle.
"We won't be too hard on him this season and I'm really looking forward to going chasing with him in the autumn. He should make a smashing chaser. He's got a lovely pedigree and is from the same family as Boston Bob. He's only really started to mature into a good horse recently."
