AURORA, Ontario – Top-ranked Jin Young Ko closed with an 8-under 64 on Sunday to win the CP Women's Open by five shots over Nicole Broch Larsen.
The South Korean pulled away with six birdies on the back nine to finish the tournament at 26-under 262, a 72-hole total that didn't include a single bogey. The last time a player has won on the LPGA without making a bogey for the tournament was Inbee Park in 2015.
Ko hasn't made a bogey in her last 106 holes.
Defending champion Brooke Henderson of Canada (69) finished seven shots off the lead in a tie for third place with American Lizette Salas (64).
Ko and Broch Larsen, who is from Denmark, entered the final round tied for the lead.
The round was broken up into trios, with groups teeing off at the first and 10th tees to ensure it didn't run up against the Tour Championship at East Lake.
Ko cemented the victory with birdies on four of her last five holes. She earned $337,500 of the $2.25 million purse with the win.
