South Korea's Amy Yang won the Honda LPGA Thailand golf tournament in Pattaya on Sunday with a 15-under-par 273.

Yang struck a 3-under 69 in the final round at the 1.5 million dollar tournament at the Siam Country Club to hold off world No. 3 Stacy Lewis from the United States, who was leading after each of the previous three rounds.

Lewis tied for second place with Chinese Taipei's Tseng Yani and South Korean Lee Mi-Rim.

Yang, 25, secured her second LPGA Tour victory after she won the LPGA KEB HanaBank Championship in 2013.
