Amy Yang and Chella Choi paced the field in the first round of the KPMG Women's PGA Championship at Olympia Fields Country Club in Olympia Fields, Illinois, on Thursday.
They each finished at five-under par, although Yang was only through the 17th hole before play was suspended because of inclement weather. Brittany Altomare finished her round with a four-under 67, while Joanna Klatten was four-under par through 16.
The full leaderboard can be found at LPGA.com.
The LPGA noted play will resume Friday at 7:45 a.m. CT.
Yang ends her day on a sour note because she bogeyed the 17th right before play was suspended and lost her solo grip on the lead. Still, she impressed with five birdies (three of which came on the back nine) and an eagle on No. 2 and will battle Choi for the lead Friday.
The LPGA shared the birdie putt on No. 14 that temporarily gave her the outright lead:
While Yang will have to shake her late bogey as she plays No. 18 and the second round Friday, Choi will start her day with plenty of momentum after birdies on Nos. 13, 14, 15 and 18 turned what was a solid round into a spectacular one.
She credited her father's advice heading into a new course:
The leaders consistently had more success on the back nine, as Altomare birdied Nos. 12, 14 and 18, while Klatten birdied Nos. 14 and 15 before play was suspended.
Elsewhere, Michelle Wie is one of six golfers at three-under par following Day 1 of competition. She, along with Brooke M. Henderson, Alison Lee and Su Oh, all finished with 68s, while Kim Kaufman was three-under par through 16 and Emily K. Pederson was three-under through 15.
Wie could have ended her day atop the leaderboard was it not for a lackluster two-hole stretch.
She bogeyed Nos. 6 and 7 to fall to one-over par for the round but came roaring back with birdies on Nos. 10, 12, 14 and 18 on the back nine. If she carries her play from the back nine into Friday and beyond, she will be a significant threat to win after finishing in the top four in four of her last five tournaments.
The LPGA captured her Thursday highlights:
While Wie stands out among the crowded group of competitors at three-under par, Henderson is the defending champion at this event and understands what it takes to thrive under the pressure-packed scenario.
She is in ideal position right behind the leaders thanks to three birdies and no bogeys on the back nine and will look to make a charge in the second round.
