SHANGHAI, 12 Oct, 2014 (AFP) - "I think I am too young to win a Masters event," Li joked. He finished the tournament at nine under, taking home $180,000 of the $1 million purse.
Winds gusting up to 40 miles (64 kilometres) per hour added to the challenge on the final day.
"I could not stand sometimes when I was putting as the wind was so strong. I never played in wind like this," Li said.
Australian Lee Jun Seok shot a 69 at the par-71 Nanshan International Golf Club to take second place while Todd Baek of Korea posted a 74 for third.
