Lydia Ko cantered to a nine-stroke victory at the LPGA Taiwan Championship on Sunday to take back the women's world No.1 spot from South Korean Park In-bee.

Ko started the final round with a four-stroke advantage and then carded a seven-under-par 65 for a total of 20-under, which also made the 18-year-old New Zealander the youngest player to earn 10 wins on the LPGA Tour.

Ko needed to win or finish second in Taiwan to move ahead of Park, who did not play in the tournament.
