The New Zealand golfer, Lydia Ko, has won her first LPGA Tour event as a professional, with a one shot win at the Swinging Skirts Classic in San Francisco.
Ko trailed the American Stacey Lewis by one shot going into the final round but worked her way into a two shot lead with five holes to play.
Lewis and the South Korean, Jenny Shin, continued to apply the pressure and cut Ko's lead to just one by the final hole.
However the 17 year old held her composure to birdie the final hole and earn her third LPGA Tour win and her first since turning professional last year.
Ko's victory has brushed away off any perceived struggles to adapt to her new equipment or coaching change.
Ko's won twice before on the LPGA tour as an amateur, but was yet to win since parting ways with her long-time coach Guy Wilson and signing an endorsement deal with equipment manufacturer Callaway last year.
However her one-stroke victory today will take her to number two in the world rankings and the chief executive of New Zealand Golf Dean Murphy, says it shows her game hasn't been affected by the changes she's made in the professional environment.
Ko's victory earns her 315-thousand dollars.
