Played as the ANA Inspiration (46th) (Mar 30-Apr 2). So Yeon Ryu (S Kor) beat Lexi Thompson (USA) with a birdie at the first playoff hole (par-5 18th). [Dinah Shore Tournament course, Mission Hills CC, Rancho Mirage, CA].
Note: Thompson was denied a second major title by the intervention of an armchair TV viewer, who spotted a "rule infringement" from Saturday's play. This led to LPGA rules officials giving Thompson a 4-shot penalty, which was advised to her on the 12th green during Sunday's play! Thompson's "crime" was misplacing her ball by a quarter of an inch (6mm) on a one-foot putt. The misplacement was unintentional, did not put the ball any nearer the hole or on a better lie, and was completely inconsequential to the score. Not for the first time, the spirit of golf was trampled on by the combination of a hyperactive TV viewer and microscopic rule interpretations, which turned the event against its rightful winner.
