香港ヴァーズ
On his final start of 2010, Mastery was sent to Hong Kong to contest the Hong Kong Vase at Sha Tin Racecourse on 12 December. He started at odds of 19/5 in a field which included the Melbourne Cup winner Americain, the Tenno Sho winner Jaguar Mail and the local champion Viva Pataca. Dettori settled the colt in third place before taking the lead in the straight. Mastery went clear of his rivals and "kept on strongly" to win by two and a half lengths from Redwood, with Americain third.
