Low scores were abundant during the early stages of the Evian Championship, where a former major champ shares the lead. Here's how things stand after the opening round in France:
What it means: Chun went out early and set the pace, while Park caught up to her in the afternoon wave. A winner last year at the U.S. Women's Open, Chun poses a formidable threat while Feng, a bronze medalist last month at the Olympics, sits just one shot off the pace as she looks to snag her second career major title.
Round of the day: Chun made quick work of the course in Evian-les-Bains, carding eight birdies without dropping a shot. That run included five birdies in a seven-hole stretch in the middle of her round, as Chun started on the back nine and made the turn in 2-under 34 before coming home in 6-under 29.
Best of the rest: Park is not yet an LPGA member, but she held the early lead at the U.S. Women's Open this summer before finishing T-3. Her opening-round scorecard also included eight birdies without any bogeys, including four in a five-hole stretch on Nos. 9-13. Park added a birdie on the par-3 16th as well as one on No. 18 to close out her round and draw even with Chun.
Biggest disappointment: The group at 2 over is a veritable who's who of American women's golf: Cristie Kerr, Michelle Wie, Paula Creamer and Lexi Thompson. But alongside them is an even more surprising name in Ariya Jutanugarn. The Thai phenom won the last major played, but she closed with a disastrous triple bogey on No. 18 to turn a middling round into an effort that left her perilously close to the projected cut line.
Main storyline heading into Friday: Jutanugarn's fight to get back into contention will be a story to watch, as will the plight of defending champ and world No. 1 Lydia Ko. Ko opened with a 1-under 71 to sit seven shots back, but she'll be out early during the second round with hopes of making more than the two birdies she recorded during the opening round.
Quote of the day: "I could see the putting lines well, and I was so good rolling the ball on those lines." - Chun
