Lydia Ko shot a 5-under 66 in windy conditions Friday for a share of the Marathon Classic lead with Hyo Joo Kim.

The top-ranked Ko had six birdies and one bogey at Highland Meadows to match Kim at 8-under 134. Kim, tied for the first-round lead with Mirim Lee and Haru Nomura, had a 68.

“I think this is the windiest I’ve ever played this course,” said Ko, the 2014 tournament winner. “In this wind and in the conditions, I feel like my score is a pretty solid one this morning.”

Ko won in consecutive weeks in Southern California this year, the second the major ANA Inspiration. The 19-year-old New Zealander tied for third last week in the U.S. Women’s Open in California.

“I started off well with a birdie on my first hole, and then made a clumsy bogey on the next hole,” Ko said. “I hit a few good shots in. I had a few birdies where it was 3, 4, 5 feet. When you got those birdie chances makes it a whole lot easier.”
