Ko dominates for history-making victory in Canada

Australian teenager Lydia Ko became the first amateur to win twoLPGA Tour events by shooting a final-round 64 to defend her CN Canadian Open title with an astounding five-shot victory in Edmondton on Sunday. 

 Ko entered the final round training Sweden's Carolina Hedwall by one stroke, but Ko's 6-under round was three shots better than anyone else in the field as she finished the tournament at 15-under. France's Karine Icher shot a 3-under 67 to take second place, while Hedwall finished in a tie for third place at 9-under along withAmerican Brittany Lincicome. 

 Ko won the CN Canadian Open in 2012, becoming the youngest winner of an LPGA event at 15 years, 4 months, 2 days. A year later, she now holds the top two spots on that record chart. 

With the victory, Ko will move from No. 19 in the Rolex Women's World Rankings to No. 7. It is her fourth international victory world wide.

Ko is the first LPGA player to defend a title since Yani Tseng won the RICOH Women's British Open in 2010 and '11.

Ko has not missed a cut in 14 LPGA events over the past two seasons.
