Dame Lydia Ko is still sweating over making the cut at the year's first women's golf major in Texas

The Aucklander's sitting in the clubhouse on one-over-par after an even-par second round of 72 at the Chevron Championship.

That's right on the projected cut line to play the weekend.

The cut has sat at one-over for most of the morning ... but has wavered between one-over and two-over ... where it's just gone back to ... in the past hour.
