Texas Jack sprang something of a surprise under a canny ride from Paul Carberry to win the Boylesports.com Bet On Your Mobile Novice Chase at Leopardstown.
Carberry crept Noel Meade's seven-year-old into the Grade Two race from the second-last and led after jumping the final fence.
However, in a thrilling finish Texas Jack (6-1) was all out to hold Lord Windermere by half a length, with Marito a further neck away in third and Mount Benbulben another in the bunch as they crossed the line.
Meade said: "He jumped brilliant and he got a brilliant ride, as per usual. I thought in the last 100 yards that they were going to come back and do him, but Paul obviously conjured up another little bit out of him.
"He's a good horse, he ran a good race here at Christmas and Paul felt going back to two mile five furlongs might suit him best, and that proved spot-on.
"He handles the ground well. We've been racing in ground like this all winter, so we're used to it.
"He might come back here for the Dr PJ Moriarty in two weeks' time, I don't know. I don't think we'll go to Cheltenham with him but if we did, maybe we'll go for the novice handicap.
"I think he'll stay at home and maybe the Powers Gold Cup is a race you could think about as well."
Carberry added: "He's a very exciting horse, he jumped very well. I decided to drop him in because the last day here he jumped very well down the back but when he got to the front, he ended up stopping on me, so I said I'd come late today.
"He did it very well, I even got there a bit soon, but when he heard the other horses coming back at him he put his head down again. I let the others do the hard work and then I came to take it off them."
