She turned professional in 2005 at fifteen. The injuries that followed, wrist and hand problems requiring multiple surgeries, came at the worst possible time, disrupting what should have been her peak developmental years and narrowing a window that had once seemed limitless. She graduated from Stanford in 2012 with a degree in communications, having carried a full course load alongside a professional career and a global endorsement schedule. In 2014, she won the U.S. Women's Open at Pinehurst by two strokes, shooting a final-round 65. It was the most prominent championship in American women's golf, on one of the most demanding courses in the country, and it confirmed what the endorsement contracts had always assumed: she was not a phenomenon. She was a golfer.

She finished her career with five LPGA Tour victories, 49 top-ten finishes, and five Solheim Cup appearances, stepping back from full-time competition as her body made the decision for her. She married tech entrepreneur Jonnie West in 2019 and they have a daughter, Makenna. The résumé is excellent. It falls below what the fourteen-year-old at the Sony Open seemed to promise, and that gap followed her for the length of her career through no fault of her own. She fulfilled almost every childhood golfer's dream. The only thing she never overcame was the impossibility of what people decided she was supposed to be.
