Pat Smullen steered the Willie Mullins-trained Renneti to a clear-cut success in the Group Three Loughbrown Stakes at Naas.
The eight-year-old bolted up in a conditions race at the Galway Festival, but had since finished down the field in the Irish St Leger Trial and a valuable handicap at Leopardstown.
Back in a smaller field, he was the 4-5 favourite to get his season back on track and saw out the two-mile distance well to score by five lengths.
Stars Over The Sea was a clear second.
Mullins confirmed the Qipco British Champions Long Distance Cup could be Renneti's next port of call.
He said: "Hopefully at this time of year he will keep getting the ground he likes with plenty of dig in it.
"He'll probably stick to this sort of trip and he could go for the race in Ascot."
Paul Midgley enjoyed a one-two in the Joe McGrath Handicap, with Leigh Roche guiding 10-1 shot Tylery Wonder to a clear-cut victory over stablemate Monsieur Joe.
Monsieur Joe was the better fancied of the two at 5-1, but Tylery Wonder never looked in serious danger of being caught in the final furlong and was good value for his length-and-a-half win.
Tylery Wonder was winning this prize for the second time having struck gold in 2015 when trained by Willie McCreery.
Midgley said: "It's a nice surprise to be perfectly honest, as I thought the ground would be too slow for him. He got a length out of the gate and never really looked like he was going to get beat.
"He battled away good on ground that is probably too slow for him.
"Monsieur Joe has run great as well. Age is probably catching up a little bit with him but he's still got plenty of will to win.
"I think Tylery Wonder finished fourth in this race last year and won it the year before. He won too well at York (in July) and the handicapper murdered him. It's taken him until now to get back to a winning mark."
Mcmunigal made a successful debut for trainer Ger Lyons in the Irish Stallion Farms EBF Maiden.
A field of 15 unraced juveniles went to post for the seven-furlong contest, with Mcmunigal a 13-2 chance in the hands of title-chasing Colin Keane.
The gelded son of Epaulette tracked the pacesetters until early in the home straight and showed a smart change of gear to to assert in the final furlong.
The Aidan O'Brien-trained James Cook, a full-brother to Breeders' Cup Turf and Prix de l'Arc de Triomphe heroine Found, was a big eyecatcher in second, beaten four lengths.
James Cook's fellow 3-1 joint-favourite Loving A Boom raced on the pace before fading into third.
Lyons said: "He's a horse that came to me from the breeze-ups. He's had a winter coat all summer, hence we took our time. He was a rig so we operated and let him get over it.
"He wasn't coming in his coat and we chose this race a while ago. The coat didn't matter at this stage. What you have seen there is what he's been at home. Anything I've asked of him, he's done.
"He's very laid back and Colin said he floated through the ground. He's not ground-dependent and there should be huge improvement as he was green when he hit the front.
"I'm not sure if we will run him again this year. We could come back here for the Tetrarch next year, something like that, but we won't be in a rush with him."
Powersville claimed a narrow victory in the Foran Equine Irish EBF Auction Race.
The Tom Mullins-trained filly was turning out just four days after finishing sixth in a nursery at Fairyhouse and was a 16-1 shot under Niall McCullagh.
The Broghie Man led inside the last of six furlongs, but Powersville picked him off and had just enough in the tank to hold the fast-finishing Sunday Smart at bay by a head.
Lyons' Curragh maiden winner Would You Believe was the 7-4 favourite and was still in with every chance when appearing to lose his action. He was pulled up and dismounted by Keane.
Pincheck justified 100-30 favouritism in the Hospitality At Naas Racecourse Handicap.
Jessica Harrington's charge was challenged by Espoir D'Soleil for much of the final couple of furlongs but kept finding for Colm O'Donoghue, who was supplementing his earlier win on Ellthea.
