Werther completed a memorable family double on Sunday with victory in the Gr.2 Hong Kong Jockey Club Cup (2000m).
His win at Sha Tin came a day after his younger brother Gobstopper produced a dominant front-running performance to claim the Gr.3 New Zealand Cup (3200m) at Riccarton.
“That was a cracking good run considering it was his second run this season,” Werther’s trainer John Moore said.
“His fitness was really tested and he will improve for this run. The speed that Harbour Master went up front really tested his fitness level, which wasn’t 100 per cent.
“We got away with it and now we go to the Hong Kong Cup. He’ll come away from this race in better fettle for that grand final.”
Werther and the Andrew Campbell-trained Gobstopper are sons of Tavistock and the Zabeel mare Bagalollies, who is back in foal to the Cambridge Stud stallion.
