Coral Wave opened her account at the third attempt with a convincing all-the-way win in the Flame Of Tara EBF Stakes at the Curragh.
The Paddy Prendergast-trained filly ran the opposition into the ground as she stormed to victory by three and a half lengths in the hands of Declan McDonogh.
Lady Wingshot did best of the rest to claim the runner-up spot with the favourite Rubina two lengths back in third.
"She's good. She loves that ground. She's a big baby and will be even better next year," said Prendergast.
"She won't be going on a boat this season. She might go for the CL Weld Park Stakes next.
"I thought she would win first time out. I've been seeing more at home than at the track."
Niall McCullagh, fresh from his win on Saddler's Rock in the Doncaster Cup, outwitted his fellow jockeys with an enterprising ride on Manieree to lift thetote.com Blandford Stakes.
McCullagh bounced the John Oxx-trained filly out of the stalls and had a soft lead with only the Johnny Murtagh-trained stablemate Kirinda and Dermot Weld's Sapphire aware to the danger of giving Manieree too much rope.
Finding plenty in the straight, the 9-1 shot went on to take these Group Two honours by three and a quarter lengths from Sapphire with Look At Me third.
Oxx said: "It has been a good week. We have nice horses running in the right races.
"She likes soft ground and improved a bit today. The mile-and-a-quarter is better for her than one mile, one furlong.
"She has been working better and better. Niall said she was very fresh on the way to the start but when he asked her to go during the race, she flew.
"She's a good filly and might be better if the ground is heavy.
"She is in the Prix de l'Opera and I'll train her for it.
"If it is a soft ground week in France she might run there. She can make the running which can be useful in France."
Cityscape outclassed his rivals with an emphatic display to win the Woodies DIY Supporting Irish Autism Action Solonaway Stakes.
The 2-5 shot, ridden by Steve Drowne, swept past the pace-setting Across The Rhine over a furlong out and quickly put the race to bed.
Roger Charlton's five-year-old went on to score by two and a half lengths from Wild Wind with Across The Rhine hanging on to minor honours.
Bewitched returned to winning form with victory in thetote.com Renaissance Stakes.
The Charles O'Brien-trained filly won this race last year and she was sent off the 13-8 favourite despite flopping at Royal Ascot and finishing out of the frame in the Sprint Cup at Haydock on her last two starts.
Dropping back to Group Three company here though, the four-year-old regained the winning thread as she cruised up a furlong out under Johnny Murtagh.
Bewitched quickly put her head in front and had three-quarters of a length to spare over Definightly at the line with Croisultan back in third.
