Hyo Joo Kim and Hye-Jin Choi handled a swirling wind and made enough birdies in their third round to build a one-shot lead at the LPGA's Dow Championship.
The South Koreans were among only six teams who broke par on Saturday (Sunday AEST), posting a 1-under 69 in foursomes to build their advantage.
After a terrific start to the tournament, double major winner Nelly Korda and Olivia Cowan made only one birdie, had a bogey on both par 5s at Midland Country Club and shot 76 to fall six shots behind.
Korda and Cowan were tied for 13th. It will be only the second time this year on the LPGA that Korda is not in the final group.
Kim and Choi, the South Korean duo who are both among the top 20 in the women's world ranking, were at 10-under 200.
