Yin’s 28-under-par total 260 (67-64-64-65) is the lowest winning score in the history of the LPGA, topping Annika Sorenstam’s previous record by a shot set in 2001. She earned $255,000 for the first-place check from an overall $1.70 million purse.

After opening with a 4-under 68 on Thursday at the Honda LPGA Thailand, four-time LPGA Tour winner Jeeno Thitikul thrilled on Friday in her home country, blitzing Siam Country Club’s Old Course with an 8-under 64 that saw her make one bogey and nine birdies in the second round.
