His Diophas was put in as the odds-on favourite, but sustained support for stable companion Slieveardagh - 3-1 to 15-8 - saw him drift to 11-10.
The money was right with Slieveardagh scoring by two and a half lengths and, indeed, was value for more than that.
Diophas cruised ahead going to two out and when Slieveardagh ballooned the flight that seemed to have settled the issue.
Tommy Treacy got a renewed effort from his charge, however, and the winner surged right away on the flat.
Said O’Grady: “Andrew (McNamara) had the choice and went with Diophas. Slieveardagh hung left at Clonmel the last day and we put a different bridle on him today and he still hung.”
Another O’Grady, this time Eoghan, who trains at Ballyclough, Co Cork, was on the mark when Maryiver took the Graun Hill Mares’ Maiden Hurdle.
Pushed ahead four out by Martin Ferris, she galloped well clear to score by ten lengths in the colours of fellow Ballyclough man, Ivor Dulohery,
O’Grady missed the contest, absent as a best-man at a wedding in Killarney, and was represented by his father, Arthur.
Commented the senior O’Grady: “She will probably run in a mares’ novice hurdle at Cork in a few weeks. She will be lightly-raced over timber and is a chaser in the making.”
Ferris enjoyed a 77-1 brace when guiding Undergraduate to victory in the Beginners Chase, giving Dromina, Co Cork trainer, Michael O’Callaghan, his first winner.
Undergraduate landed in front over the second last and quickly ran clear for an easy 11 length success.
O’Callaghan, who has four horses in his care and has been training for two years, said: “He’s a grand little horse and will now go for a handicap.”
Eoin Doyle’s Without The Bop stayed on strongly, in the hands of Shay Barry, to take the Pickardstown Handicap Hurdle.
Barry drove him between horses to lead between the final two flights to easily beat Golden Gem.
Said Doyle: “He won three point-to-points and wants better ground. He’s taken a while to come to himself and will be a chaser.”
Doyle and Barry completed a 155-1 double when 25-1 shot Satu made a successful debut over jumps in the Guillemene Maiden Hurdle.
He was impressive as well, bounding ahead over the second last, before easing away from Minnie Wyse.
“I bought him at the horses-in-training sale from David Myerscough”, said Doyle. “I wasn’t expecting that, but he could be a nice horse.”
Andy Slattery’s Blank Hand, a 12-1 chance, was much too good for the opposition in the Newtown Handicap Chase. Partnered by Roger Quinlan, he powered into the lead approaching two out to score by ten lengths.
It was an excellent training performance on the part of Slattery, Blank Hand having been off the track since suffering an injury in this contest a year earlier.
Carrig Cottage, who hadn’t run since May, stripped fit and well to win the Bumper for the Killeagh, Co Cork yard of Martin Fitzgerald.
The daughter of Presenting, who now goes hurdling, got to the front off the home turn to beat Whats On The Menu.
Carrig Cottage was ridden by Jennifer Pugh, this was her first, who is a doctor by profession.
Crannaghmore Mist, backed at 11-8 in the morning and returned at 4-6, proved hugely disappointing and was struggling three furlongs down before finishing fifth.
