Wenyi Ding capped off a marathon Sunday with a 3-under 67 that carried the 19-year-old from China to a one-shot victory in the Asia-Pacific Amateur and a spot in the Masters and the British Open next year. Ding, a sophomore at Arizona State, had to play 14 holes to complete a 67 that left him tied for the 54-hole lead with Ziqin Zhou of China.
