Ko stormed onto the world stage as a teenager, becoming No. 1 in the Rolex Rankings at 17 years, 9 months and 9 days, the youngest to achieve that status. When she won the 2015 Evian Championship, she became the youngest woman to win a major championship. Ko had been the No. 1 player in the Women’s World Amateur Golf Ranking for 130 weeks when she turned pro in October 2013. By then, she had already captured the 2012 U.S. Women’s Amateur, been a semifinalist in the 2012 U.S. Girls’ Junior and low amateur in the U.S. Women’s Open (2012). Ko was the low individual scorer in the 2012 Women’s World Amateur Team Championship while representing New Zealand. Ko twice won the CN Canadian Women’s Open (2012 and 2013) as an amateur, and won the event for a third time in 2015. This will be her ninth start in the U.S. Women’s Open, with a best finish of T-3 in 2016 at CordeValle.
