Crystal View added to a similar Premier Nursery success at Tralee last month with an impressive victory again under talented apprentice Chris Hayes in the E50,000 feature on day two of the Festival.
Hayes (17) from West Limerick, brought the Kevin Prendergast-trained juvenile wide in search of better ground entering the straight, and the 7/1 shot drew clear to beat Brogue Lanterns by 4 1/2L.
Paul Nolan saddled his first two-year-old winner when Sky High Flyer got up in the final stride under Tadhg O'Shea to pip Ciaras Diamond in the six furlongs fillies maiden.
'She was a bit green again and is not used to going at racing pace as we take it steady with them on a sand gallop at home. Hopefully she'll go on to better things,' said Nolan.
The Wexford trainer also had news of stablestar Cloone River who may go for a Grade 3 novice chase at Roscommon on October 4 before travelling over to Cheltenham in November.
Lake Andre made all in the other Flat race on the card - 7f auction maiden - driven clear by Fran Berry inside the final furlong to beat the well-backed Galarini (3/1-9/4f) by three and a half lengths.
Urban is on course for the Denny Hurdle at Leopardstown on St Stephens Day after routing the opposition in the 3YO winners hurdle.
Barry Geraghty's mount jumped to the front before three out, and his superiority was exaggerated further after Bacon Butty blundered and unshipped David Casey at the second last.
'He loved the heavy ground and will probably have one more run before the Dennys,' said Joe Crowley's assistant Damian Byrne.
Out The Gap proved a clear cut winner of the handicap hurdle under a dashing ride by Tommy Treacy, cruising to the front between the final two flights and sprinting away on the run-in to beat Brouling by three lengths.
'He's out of a half-sister to For Auction, and it looks like he also needs to be held up for a late run. He may run again at Tipperary in a fortnight,' said trainer Colman Hennessy.
Mirpour (7/4) justified favouritism in the beginners chase but only after a titanic tussle with Jack Of The Cross in the straight, and Ruby Walsh's strength proved crucial in the closing stages.
'He pulled out all the stops and looked beaten twice in the straight. Ruby said he hated the ground, and he'll go to Tipperary for the Kevin McManus novice on October 3,' said trainer Eoin Griffin.
Phillip Fenton saddled his first winner under rules when Slipereer, also a first success for Clonmel amateur Brian Corcoran, got the better of fellow newcomer Scottish Highland by 1 1/2L in the bumper.
