Katherine Hull fired a three-under-par 69 to win the LPGA Canadian Women's Open by one stroke on Sunday.

South Korea's Se Ri Pak was second just one shot behind Hull who finished at 11-under 277 total.

Taiwan's Yani Tseng entered the day with a four-stroke advantage but she collapsed in the final round with five bogeys and a double bogey to shoot a 77 to finish in third place.

Hull had three birdies on the front nine and added one more coming in. She had just one bogey, playing steady golf while Pak and Tseng did anything but.

Pak birdied the final two holes for an even-par 72, but was just not able to overcome her mistakes.

She bogeyed numbers four and five and then carded a double-bogey at the par-5 sixth. She had three birdies in four holes starting at the seventh to get back in the hunt but a bogey at 16 ultimately left her a little short.

Tseng started her round with a big lead but wasted little time giving it all back. She had five bogeys, including three-straight on the front nine, a double-bogey and just two birdies.

Tseng was looking for her second win of the season. She won the LPGA Championship and was coming off a second-place finish at the Women's British Open.

Michelle Wie closed with a 71 to finish tied for 12th at three-under.
