Wonderfully led home a one-two for Aidan O'Brien when making all in the Silver Flash Stakes at Leopardstown.
Jumped out quickly by Joseph O'Brien, the pack never really got to the 13-8 favourite, who had last been seen finishing seventh in the Albany Stakes at Royal Ascot which is working out extremely well.
Sporting a visor for the first time, the daughter of Galileo had a length in hand over stablemate Perhaps, who came home strongly in the hands of Seamie Heffernan.
O'Brien pointed towards the Debutante Stakes at the Curragh on 11 August for Wonderfully and said: "She is an improving filly, she's lazy in front and that's why she had the visor on.
"She's very idle and Joseph wanted to put it on. It helps.
"She stayed on well at Ascot. She's a nice filly and would have no problem getting a mile as a three-year-old."
He said of Perhaps: "She is a nice filly, she's still green looking and Seamie (Heffernan) said she was still very raw.
"It was a good education stepping her up into a stakes race and we're very happy with her.
"She'll have no problem with a mile next year."
Royal Diamond justified short-priced favouritism for trainer-jockey Johnny Murtagh in the Listed Challenge Stakes.
Last year's Irish St Leger winner, sent off at 5-4, soon opened up a big advantage in front, being well clear with a mile of the mile and three-quarters still to run.
Nothing ever seriously looked like narrowing the gap and Murtagh was able to ease his mount significantly close home, as Sir Ector ran on to take second.
O'Brien's Geoffrey Chaucer (2-7), a Montjeu half-brother to Shamardal, landed the odds from the front on his debut in the Irish Stallion Frams EBF Maiden, but he had to work a bit harder than expected and only held off the challenge of Tarfasha by a rapidly-diminishing neck.
O'Brien jnr tried to repeat the feat by leading on Il Palazzo and she looked the most likely winner of the Discover Ireland Dublin Horse Show Maiden halfway down the straight, but she was thwarted by another Coolmore representative as the David Wachman-trained Goddess Of Love (7-1) swooped by to score by three-quarters of a length.
Not be outdone by her brother, Ana O'Brien got on the scoresheet as Fairylike (4-1) completed a treble on the night for the Ballydoyle operation in the "Hot House Flowers" Apprentice Handicap.
There was a big prize up for grabs in the Irish Stallion Farms EBF "Nasrullah" Handicap and it went the way of Dermot Weld's Tandem (6-1).
