20/1 shot Irish Impulse stayed on best on the run-in to spring a shock in the Prior Park Service Station Handicap Chase at Clonmel.

Three jumped the last together as Philip Enright came up the inner to tackle Bite That and Crowsatedappletart

It was the Robert Tyner-trained grey who asserted in the closing stages to record a length-and-a-half win over Bite That.

The winner was stepping up significantly on previous form, having been pulled up on his chased debut at Tramore last time.

"I had a huge advantage having Philip as he was worth a lot around there. He didn't miss a beat, got a great run and hardly left 'the paint'. He gave him a great ride,” said Tyner.

"In Tramore he didn't jump well and they probably went a bit fast early on and he got taken out of his comfort zone.

“We were hopeful going there as he was working nicely but he was never happy and he had to pull him up. We were surprised that he ran disappointingly.

"Like all the horses, we're hoping he'll improve so we'll see how he goes. I bought him off Jim Mernagh in Tattersalls and he is an active, loose horse."
