Black Quartz rallied in game style to pip Corcovada in Galway's Irish Stallion Farms EBF Premier Nursery.Aidan O'Brien's top-weight was headed by Edward Harty's charge inside the final furlong after trying to make virtually all the running. However, the 4-5 shot answered Johnny Murtagh's every call to get back up in the last stride and win by a short head. Fammi Sognare was third."It was a good performance to win carrying top weight. He's a fine big horse. When the other horse came at him he fought back well," said Murtagh.
