Needing a birdie on the par-five last to join Ji Yeong Kim as the clubhouse leader on 14-under, Ko bladed her third shot to within eight feet, but her lead-tying putt rolled past the hole and she was forced to settle for par, and a share of fifth.
In the end, a final birdie would have only been good enough for tied third, with Lee, who had been leading all day, finishing at 15-under after parring the final hole, and she was joined by Song, who hit her approach to six feet and then rolled in the birdie putt to rather annoyingly ensure that the event headed to a playoff finale after the Herald's first edition print deadline.
Fortunately for you, valued Herald online reader, we can report that Song eventually prevailed with a birdie on the third playoff hole, after the pair had carded pars on their first two attempts to find a victor.
