With her first three rounds at the 2018 Thornberry Creek LPGA Classic, Sei Young Kim was at 27-under total and within reach of seizing the LPGA Tour's 72-hole scoring record.
The LPGA Tour's 72-hole scoring record is 257, which was set by Sei Young Kim in the 2018 Thornberry Creek LPGA Classic, with a 31-under total. The prior record was 258, which was set by Karen Stupples in the 2004 Welch’s/Fry’s Championship at Dell Urich Golf Course, Tucson, Ariz., with a 22-under total. Wendy Doolan won the tournament the year prior on the same course with a total one stroke worse.
The Tour's scoring record in relation to par for a 72-hole event is also owned by Kim. Her 31-under total at Thornberry Creek is the second-best 72-hole total in any professional golf tournament. The prior record was shared by Kim and by Annika Sorenstam, who shot 27-under total of 261 in winning the 2001 Standard Register Ping at Moon Valley Country Club, Phoenix, Ariz. -- a four-round total that included the LPGA Tour's only ever 59. Kim shot 27-under total in winning the LPGA's Founders Cup. Karrie Webb shot 26 under par in winning the 1999 Australian Ladies Masters Royal Pines Resort.
The LPGA Tour 54-hole scoring record also belongs to Kim, from the Thornberry Creek LPGA Classic, and Sorenstam shot 192 -- a 24-under total -- through the first three rounds of the 2003 Mizuno Classic at Seta Golf Course in Japan. That 24-under total is also good enough for the LPGA record for 54 holes against par.
The 36-hole scoring record on the LPGA belongs to, you guessed it, Annika Sorenstam from the 2001 Standard Register Ping. Her 65-59--124 total set the record against both par (20-under total) and in aggregate.
Sorenstam's 59 is the only sub-60 score in LPGA history, with four players shooting 60 at different points in LPGA history.
