Black Quartz produced a game front-running performance to defy top-weight in the EBF Premier Nursery under Johnny Murtagh. Corcovada came with a strong run to dispute inside the final furlong but was just edged out close home by the 4/5 favourite.

"It was a good performance to win carrying top-weight," said Murtagh afterwards.

"He's a fine big horse. When the other horse came at him he fought back well."
