The New Zealander is tied at the top of the leader board with Danielle Kang at -7.

One bogey on the eighth hole was the only blemish in an otherwise strong opening round that saw her hit eight birdies.

"I hit a few shots that were in tap in range, when you have 3 or 4 of those opportunities it puts a little stress off the putter," she said.

Highland Meadows Golf Club course in Sylvania holds fond memories for Ko.

The 23-year-old has won twice there before, had two other top ten finishes and since 2012 her scoring average at the event has been 68.
