In the first year of the new USGA two-hole aggregate playoff format, the playoff was held on holes 14 and 18, both par fours. Jutanugarn parred both while Kim went birdie-bogey to stay tied and it moved to sudden-death, using the same holes only. Both parred the 14th hole, but Kim again made bogey at the 18th hole while Jutanugarn made another par and won the championship.
