The favourite had one major danger removed when the challenging Arnaud, who had made most of the running, fell when on terms at the second last.
Mount Colah was left nicely clear, but then crashed into the final fence and was very lucky to survive.
His rider, Noel McParlan, quickly picked him up and the nine-year-old found enough to beat Letter Of Credit by a length and a half.
“He was idling when on his own,’’ said a relieved Cosgrave. “I think there’s a race for him here next Thursday week (Grade 2 Kinloch Brae Chase) and that is likely to be next.’’
Paul Nolan, who has his charges in good shape right now, was on the mark when I’m All You Need took the INH Stallion Owners’ EBF Maiden Hurdle.
The daughter of King’s Theatre had hinted that her turn mightn’t be long delayed when runner-up behind Keppols Queen at Clonmel and duly went one better.
Produced by Mikey Fogarty to lead heading to the last, she found plenty to easily beat Hes Our Robin.
“She battled well at Clonmel the last day, is after growing again and will improve,’’ reported Nolan. “We will stick her into one of those mares’ races now.’’
Gamble of the contest was New World, returned at 5-4 from 7-2 in the morning. He was in trouble a fair way from home.
Roi Des Francs, having a first outing for Willie Mullins, was far too good for market leader, Venitien De Mai, in the thurles.ie Maiden Hurdle.
Venitien De Mai was strong in the market and this splendid jumper attempted to make all of the running.
But he had no answer to Roi Des Francs, once Bryan Cooper pushed his charge into the lead between the last two flights.
“He is going to be a three-mile chaser,’’ said Mullins.
“He could come back here for the Purcell Hurdle and will get an entry in the Neptune and Albert Bartlett at Cheltenham.’’
Mullins was back in the winners’ enclosure after Honeys Joy benefited from an extraordinary drive by his son, Patrick, in the Bumper.
By now the track resembled a ploughed field, but Patrick solved that by racing miles wide, on a far better surface, throughout.
It reaped a rich dividend, as the daughter of Kayf Tara came up the stands’ side in the straight to beat Kala Brandy by eight lengths.
Commented Mullins senior: “Patrick felt it was worth taking a chance going wide and it worked. She will go jumping now.’’
The Thurles Racecourse Handicap Chase was a modest contest, but was won in good style by the John Joe Walsh-trained Glen Ode.
Available as high as 10-1 in the morning, he was returned the 7-2 joint favourite with Western Promise.
Glen Ode did get in tight to the fourth last, but it made no difference and was able to stroll up the straight to score with plenty in hand.
Said Walsh: “He was fierce unlucky here the last day, he made mistakes. We thought he wanted better ground, but maybe that’s his ground.’’
Walsh completed just over a 30-1 double when Brian O’Connell drove top weight Hard Bought to victory in the Munster Handicap Hurdle.
A big leap at the last by the front-running Fort Carson looked as if that had sealed the deal, but the winner nailed the leader on the line to score by a head.
“He could have won at Limerick the last day, he got left at the start,’’ said Walsh.
“Brian gave him a good ride.’’
Ricky Doyle, a 7lbs claimer, gave Zipporah a terrific drive to take the Horse And Jockey Handicap Hurdle.
Doyle had the daughter of Millenary striding along in front from the start and she soon held a huge lead.
Zipporah never promised to come back to her field and crossed the line no less than 14 lengths clear of the second, Bloomsday.
