An Cathaoir Mor, trained by Henry de Bromhead and ridden by David Casey, has won the Grade One Frank Ward Solicitors Arkle Novice Chase at Leopardstown.
An Cathaoir Mor registered a dramatic success as he came from well off the pace in the race.
After Zaarito crashed out at the third fence in the Grade One heat, it looked as though the race was between just three runners, with Major Finnegan, Take The Breeze and 2-1 favourite Sports Line dominating the early stages.
The trio were still fully 10 lengths clear when Sports Line hit the front for Ruby Walsh at the third-last fence, with An Cathaoir Mor back in fourth under David Casey.
However, the complexion of the race changed in the straight as Casey made stealthy headway on the Henry de Bromhead-trained 7-1 shot.
Coming down to the last, An Cathaoir Mor had made up the deficit and was still full of running in second as Sports Line began to toil and the other pair faded out of contention.
It was left to An Cathaoir Mor to shade out the favourite in the shadow of the post, going a length and a quarter clear at the finish.
