India's Aditi Ashok shot her best total of the year but still finished tied 35th at the low-scoring Thornberry Creek LPGA Classic golf tournament here.
She reached 30-under par in the Thornberry Creek LPGA Classic.
Kim closed with a seven-under-par 65 for a nine-shot victory to break the record she had shared with Annika Sorenstam.
Kim began the final round with an eight-shot lead and played magnificent golf all day. She surpassed her own and Sorenstam's record with a birdie on nine.
Torres made seven birdies against just one bogey for her 66 on Sunday.
Kim was dominant throughout the weekend. A birdie on 15th saw her still at 13-under, but a double bogey on par-3 17th dropped her down before she finished with a birdie on 18th. She's a great player.
It breaks the previous record of 27 under, set by Sweden's Annika Sorenstam in 2011 and then by Kim in 2016. Kim had a four-day score of 27-under at the 2016 JTBC Founders Cup, while Sorenstam posted that same score at the 2001 Standard Register Ping in Phoenix.
The 32 holes under par is another record, breaking the mark of 30 set by Brittany Lincicome, Gerina Pillar and Lexi Thompson at the 2017 Bahamas LPGA Classic. The Thornberry first-place check of $300,000 pushed Kim's career earnings past $5 million, making her the 61st player to reach that plateau in LPGA history.
"I never thought about shooting, like, 31-under". It wasn't good result and I kept think about it, What's wrong with me? "Today my putting was very good, so very happy with the way I played".
The South Korean fired an eight-under-par 64 third round on Saturday to get to 24 under and take an eight-shot lead from countrywoman Amy Yang (67) in Oneida, Wisconsin. Kim earned her full time status card on the LPGA Tour after finishing tied for ninth at the 2014 LPGA Qualifying Tournament.
Kim, who is seeking her first win of the season, was a disappointing 25th at last week's KPMG Women's PGA Championship. However, after a win in May 2017, Kim struggled to add another win until Sunday. The only blemish of her round was a double bogey on 18.
It was also the seventh win by a South Korean during this season's LPGA Tour.
No one had a chance Sunday. Yang, with a birdie on the final hole for a 68, tied for third at 20 under with Emma Talley and Anna Nordqvist, who each had a 67.
The LPGA Tour next moves to Sylvania, Ohio, for the Marathon Classic, before heading to the United Kingdom for the British Open from August 2-5.
