Quartz crystal clear for O'Brien

Aidan O'Brien's Black Quartz added his name to an illustrious roll of honour for the Whitney Moore EBF Maiden at the Curragh this afternoon.

Both Teofilo and New Approach collected the seven-furlong event as juveniles while Sea The Stars was fourth on his debut last year.

Black Quartz has a fair bit to live up to as he was beaten on his first two starts and was only the mount of Johnny Murtagh when the well-bred Fighting Brave was pulled out.

The even-money favourite made most of the running for a controlled half-length defeat of Jim Bolger's Reiteration, who made a promising first appearance.

Black Quartz was installed at 25-1 for the 2000 Guineas, and O'Brien said: "He was just idling in front at the end and Johnny said the ground is very soft.

"He's very babyish - he improved a lot between his first and second runs and will improve again."

Murtagh looked booked for a rapid double in the Listed Kilboy Estate Stakes before he was mown down by Danny Grant aboard She's Our Mark.

Murtagh was soon a long way clear on Latin Love and it was only at around the furlong marker when his advantage unravelled.

First Timabiyra failed with a challenge before She's Our Mark powered down the outside to win by two lengths.

Pat Flynn's mare was a respectable fifth in the Windsor Forest Stakes at Royal Ascot and made the 9-4 favourite here.

Grant said: "I think that's the fifth time she has won now.

"She just takes her time to get going and really loves to have something to chase. Even though we were quite far behind Johnny I was always confident."
