Amy Olson heads into the final round of the Evian Championship with a two-shot lead after a flawless Saturday performance put her in pole position for a first major.
In her 18th year on tour, after a wild and tearful final few holes, Angela Stanford became a major tournament champion Sunday.
Among the players in a four-way tie for second was the overnight leader Amy Olson who led by three with five to play and teed off the 18th with a one-shot lead, only to double-bogey it and hand victory to Stanford.
Seven-time LPGA Tour victor Kim Sei-young of South Korea is the nearest challenger lies at 12 under after a spotless 64, while American Mo Martin a further two shots back in third spot on 10-under.
In an enthralling finish, the 40-year-old Texan became the first American victor of a major this season successfully holding off a magnificent charge by her compatriots as six finished in the top eight. Stanford waited greenside out of sight of the putting surface after signing autographs for young spectators.
"That was huge", said the 26-year-old North Dakota native, whose career-best finish in a major is tied for ninth at the ANA Inspiration this season.
Playing in the second-last group, Stanford went eagle-double bogey-birdie from the 15th, then saw her birdie chance brush the hole on No. 18.
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.
"It's really easy for the wheels to come off here", Stanford said. She padded her lead to three with a tap-in for birdie at the par-5 13th. Soon, Stanford punched the air with her right fist when sinking a 25-footer for birdie on 17th.
Refusing to check the leaderboard all day, Olson said she only knew on the 18th tee where she stood.
Stanford finished at 12-under-par 272 after carding a 3-under 68 in the final round.
On a stellar day for the Americans, 16-year-old amateur Rachel Heck (71) tied for 44th in her second major. A 40-foot par putt for victory raced past.
Stanford says it's been hard being away from her mother during events, but her mother wants her to play and relishes rooting for her.
Having already won the other four majors some have questioned if she needs to win the Evian again to claim a career Grand Slam but Park herself is indifferent.
