The LPGA has seen its share of incredible playoffs over the years, and there have been some US Women's Open and other majors which went to a required 18-hole playoff. However, most weeks, the LPGA's playoff format is sudden-death.
Usually, sudden-death playoffs go maybe a few holes at most. They don't typically go past a third hole. A few times in LPGA history, though, a playoff has gone an incredibly long way to determine a winner.
The longest sudden-death playoff in LPGA history is nine holes, back when Jiyai Shin beat Paula Creamer for the 2012 Kingsmill Championship in Williamsburg, Va. Shin won with a par on the ninth hole. The first eight holes of the playoff were completed on Sunday night, playing the 18th hole at Kingsmill Resort again and again without a winner. The playoff spilled over into Monday for the completion, with Shin finally taking the win on the first Monday hole.
The old record was seven extra holes, set in Cristie Kerr's victory over Seol-An Jeon in the 2004 LPGA Takefuji Classic.
The longest LPGA sudden-death playoff in a major belongs to Inbee Park, Pernilla Lindberg and Jennifer Song at the 2018 ANA Inspiration. That playoff went eight holes, with Lindberg winning with a birdie on the eighth playoff hole. Jennifer Song was eliminated after the third playoff hole, while Park and Lindberg continued into Monday to finish.
