Partnered by in-form David Casey, enjoying his third success of the meeting, Cool Running powered ahead over the fifth last.
It was bar a fall from that point, as he strolled away from outsider Shan Brogeen and well-backed Arc En Ciel.
Frank Berry did the honours for owner, J P McManus, and said: “He did what you’d expect him to do and will tip away for the summer.”
Manorville, a full-sister to ill-fated Stoneville, took the Irish Stallion Farms’ EBF Mares Maiden Hurdle at odds of 14-1, over 26-1 on the Tote.
Brian Byrnes drove her ahead in the straight and she kept going to beat Sian Thomas cosily enough by two and a half lengths.
“She’s not as a good as her brother, but will win races”, said trainer, Eric McNamara. “She will have a break now and come back over hurdles at Listowel. She will make a lovely chaser in time.”
Bernadette Murphy, who has held a licence for about a year and a half, had her first winner when Ruby Walsh guided The Boss Roche to victory in the Sean Clifford Housing Developments Handicap Chase.
Walsh made his move heading to four from home and The Boss Roche answered every call to beat On You Go.
Murphy, who trains in Wexford, missed the race, canvassing instead for Fianna Fáil candidate John Browne.
Johnny Gonzalez, taken from evens to 4-5, was a costly failure. He made a dreadful blunder at the second and Mikey O’Connor did really well to stay with him. The hot-pot could never get in a blow after that.
Willie Mullins’ Temlett redeemed the promise of his seasonal debut at Ballinrobe with a clear-cut success in the Irish Stallion Farms’ EBF Median Auction Maiden.
Pat Smullen soon had him striding on and didn’t have to be in any way hard on his charge to coast home two and a half lengths clear of Ragged Staff.
Commented Smullen: “He was entitled to win, but will have to step up now. I’d imagine his future lies over hurdles!”
Mark Prescott’s Souvenance was long odds-on for the Killarney Racegoers’ Club Race and did her job well enough in the hands of Declan McDonogh.
The champion jockey drove her into the lead over two furlongs out to beat Oscar Night comfortably.
Prescott was represented by travelling head girl, Hannah Barker, who reported: “Mark is very clever at finding races like this. I don’t know whether she will stay for a while, we will see how she is.”
Colm O’Donoghue, fresh from his tremendous triumph on Astronomer Royal in the French 2000 Guineas at Longchamp on Sunday, turned his attentions to lesser pickings when taking the Cahernane House Hotel Handicap on Lake Pontchartrain.
The top weight stayed on strongly late to gather in the front-running Fareeji and score by half a length.
Chris Hayes was aboard Fareeji and he made no mistake in the next contest, the first division of the M D O’Shea and Sons Handicap, when sweeping through late on Kilmannin.
It was a similar story in the second section with Davy Moran producing Martin Lynch’s Market Minstrel late and fast to beat Freda’s Choice.
