For leader Olson the stakes are somewhat different, the fourth-year professional yet to win any event on the LPGA and boasting only four top 10 finishes since joining the circuit in 2014.
At 40, Stanford is still waiting for that elusive major, but she's giving herself a chance at the Evian Championship.
"I'm simply asking all of you to keep her in your prayers and to love those who mean most to you", Stanford wrote in making the announcement this summer in an Instagram post.
Angela Stanford has attributed her Evian Championship victory to how she has always been a "fighter", at the same time dedicating the win to her cancer-stricken mother. I wish I could, " said Kim, a seven-time victor on tour.
"It's something new and it's exciting [to lead]", said the 23-year-old Torres, who is ranked No. 184. "It's forcing me to stay in the present and just hit one shot at a time".
Stanford, who eagled the 15th but then double-bogeyed the short 16th in a roller-coaster round, thought she had lost her chance of victory when she failed to make birdie at the 18th. I haven't seen a lot of big misses or anything that you have to worry about.
Olson's two-shot lead was soon restored after Kim's double bogey 6 at the 10th.
Stanford moved to 13 under with an eagle at the 15th but then immediately gave those two shots back by taking five at the next.
Olson went to the 17th tee with a one-shot lead on 13 under as Ernst set a clubhouse target of 11 under.
Olson committed to not looking at leaderboards throughout the day, and it wasn't until she was sizing up her options from the rough on the 18 that she asked brother Nathan, her caddie, where she stood.
A par four would have won it for her, but she hooked her tee shot into the rough, and her third-shot approach was well below the pin. A par putt for victory raced past. Her 2-over total of 286 tied with defending champion Anna Nordqvist.
However, one of those came earlier this year when she played in the final group Sunday at the year's first major, the ANA Inspiration, and ultimately finished T9.
Bae finished at 19-under 265, closing with a 5-under 66 at Hillcrest Country Club to edge Anders Albertson (62), Roger Sloan (63), and Adam Schenk (64).
Vijay Singh, a three-time victor at Warwick Hills in the PGA Tour's defunct Buick Open, was 7 under along with two-time Warwick champion Kenny Perry (67), Bernhard Langer (67), David Toms (70) and Joey Sindelar (67).
