Galitsky closed with three birdies in her last four holes as she played solid and steady through the final day. She made the turn at one-under-pa with a birdie on the sixth hole. Her only dropped shot came when she shockingly missed a one-footer par putt on the 14th hole, but then bounced back in incredible fashion with birdies on the 15th and 16th.
Kim, ranked number 14 in the world, was bidding to become the first player from Korea to win the WAAP title. However, despite giving herself several birdie opportunities, her putter remained cold.
As the 2023 WAAP champion, Galitsky earns dream starts in three major championships -- the AIG Women's Open, The Amundi Evian Championship and The Chevron Championship -- as well as the Hana Financial Group Championship, ISPS Handa Australian Open, The 120th Women's Amateur Championship and an invitation to play in the Augusta National Women's Amateur (ANWA) later this month.
Korea's Yeji Park (70), Japan's Yuna Araki (72), the second-highest ranked player in the championship at number five, New Zealand's Fiona Xu (71) and Sophie Han (71) of Hong Kong, China, were tied for the third place at six-under par 282.
Galitsky, who also holds a Canadian passport, was ahead by four going into the back nine of the championship Sunday. Her win was never in doubt.
Kim finally made a putt and a birdie on the 16th hole and followed it up with another on the 17th. She was three ahead of the pack in third place at the stage and tried to set up an eagle on the 18th hole in the hope of putting some pressure on the leader. However, her second shot rolled through the green and into the water hazard.
Chinese Taipei's Ting-Hsuan Huang (70), winner of the championship last year, finished in solo ninth place in her title defence, while Japan's Rin Yoshida, the highest-ranked player in the field at number four, shot a three-over-par 75 to be tied for 28th place at five-over par 293.
