Lydia Ko has won her third Canadian Women's Open, beating world number three Stacy Lewis in a playoff.
Ko won the sudden-death playoff on the first hole, holing a three footer for par to defeat Lewis, who could only manage a bogey.
Ko began the day in a share of the lead and moved out to a two-shot lead following a birdie on the par three third. But the 18-year-old dropped a shot at the par four ninth to move back to 12-under.

She parred the back nine to end up firing an even-par 72, and joining the playoff with Lewis, who shot a 67.
