Aidan O'Brien's Concert Hall produced a telling late challenge to win the Weld Park Stakes at the Curragh.
The daughter of Ballydoyle's 2012 Oaks winner Was, with Seamie Heffernan on board, appeared to need all of the seven-furlong trip to get on top in this Group Three.
Concert Hall, successful over course and distance in a July maiden, was sent off at 9-2 after finishing out of the first three at Group Two and Group One level at the Curragh over the past two months.
She was still only seventh two furlongs out, as British challenger Lovely Mana and eventual runner-up Sunset Shiraz were among those to the fore on the far rail.
But Heffernan delivered Concert Hall with a sustained run wide of her rivals down the middle of the track, and she got to the front to win by a length - with Seisai staying on for third, a further neck away.
O'Brien, who was winning this race for the fifth time in the last 10 years, said: "I'm delighted with her, and if she comes out of this OK she'll probably step up and go on to the Fillies' Mile.
"She's a hardy lady and is going to improve from racing. She stays well and is a good, strong build."
Dermot Weld's dual Classic heroine Search For A Song returned to her best form with an impressive success in the Group Three Raa Atoll Loughbrown Stakes.
Search For A Song won the Irish St. Leger in 2019 and 2020 but, after a mid-summer break, could finish only sixth behind Sonnyboyliston in pursuit of a famous hat-trick at this same course on Irish Champions Weekend a fortnight ago.
Back up to two miles, for only the second time in her career, last year's Long Distance Cup runner-up appeared to both relish the extra stamina test and demonstrate her liking once more for the Curragh as she surged to a near 10-length victory from even-money favourite The Mediterranean.
Debutante Dun Na Sead was an eyecatching, all-the-way winner of the opening William Hill Ireland Acca Freedom Irish EBF Maiden.
Kieran Cotter's Starspangledbanner filly was in front immediately on the stands side, and never in any danger as she raced clear of the field throughout on the way to a length-and-three-quarter victory at 15-2.
New Energy was a second successive all-the-way winner, in the William Hill Ireland Play Responsibly Irish EBF Maiden - and he too earned rave reviews from his trainer, after beating Sir Antonio by two and a half lengths.
Jockey Robbie Colgan always appeared confident on the 11-1 shot, and winning trainer Sheila Lavery said: "I have to thank Gary Halpin, who gave this horse a big recommendation.
"I left him in today but I was praying for rain just to ease the ground a bit.
"I thought so much of him that he had an entry in the Beresford but I didn't want his first run to be at that level and have a hard race.
"He has a Guineas entry, and I think he's something very special. He has a very natural high cruising speed."
New Energy is likely to run again this season, possibly up to Group Three class at Leopardstown next month.
"He ran twice in barrier trails," added Lavery.
"He was very green the first time, when I didn't put a cross noseband on him, and he won the second time.
"I would love to run him in a winners-of-one, but those sort of races are really missing from the programme. He could go for something like the Killavullan Stakes at Leopardstown."
