Mi Hyang shot a course-record 63 in the final round to beat Ko by one shot. Lee is a 20-year-old described as "bubbly" in this account of her victory. Her rookie year on the LPGA was 2012. (The New Zealand Open is a Ladies European Tour event.)
In 2013, Lee made 10 cuts in 17 starts on the LPGA (keep in mind she was only 19 when the 2013 season began). That included a round of 64 at the Manulife Financial LPGA Classic, her previous best tournament round as a pro. She also was seventh overall on the LPGA Tour in eagles last year.
Lee's win is being called, in some places, her first professional victory. But that is not the case: She won a Symetra Tour tournament in 2012, when she finished the Symetra season sixth on the money list.
