My Murphy digs deep to land Thyestes Chase for Liam Burke and Robbie Power
My Murphy repelled the late challenge of Mala Beach to land the Goffs Thyestes Chase at Gowran Park.
Robbie Power had his mount - who was second to subsequent Gold Cup runner-up Djakadam 12 months ago - prominent throughout the final circuit, serving it up to Ballycasey from some distance out in the three-mile-one-furlong event.
He had that rival beaten coming to the penultimate obstacle but Davy Russell was just getting 5-1 favourite Mala Beach to hit top gear.
However, the Liam Burke-trained 16-1 winner dug deep for Power on the run to the last and after the pair were neck and neck over the final jump, My Murphy just hung on for a length and a quarter success.
Ucello Conti appeared to be in with a shout after Jacques Ricou steered a wide course throughout, but a mistake at the second-last saw him drop back for third. The Job Is Right was fourth.
A delighted Burke said: "I very nearly didn't run him as he ran a stinker the last day and he only came right in the last couple of days. But to be honest it was all down to the ride Robbie gave him.
"He has to be up with the pace and he didn't let him lose his position and it was a super ride. He had a heavy fall at Navan in the past and now doesn't travel among horses.
"He had been knocking on the door, but got no run the last day. He missed the break from a standing start and his race was over at the first.
"The handicapper dropped him a pound which helped but when he got under the third-last, I thought 'here we go again!'."
My Murphy was seventh in last year's Irish Grand National at Fairyhouse and will again have that race as a target.
Burke said: "He's not fast enough for Cheltenham and will probably run next in the Bobbyjo Chase and then try the Irish National again.
"I've won the Galway Plate and Irish Arkle, but this is the one that has pleased me most as it was the one race as a young fellow that you'd love to win. We used to listen to it on the radio at school and I remember horses like The Godfather winning it."
He added: "His owner Hans Joerg Zindel is Liechtenstein-based but has a property in Lismore, Co Cork and is in South America at the moment for five weeks."
