During the first day at the Congressional Country Club in Bethesda, Maryland this weekend, Chun In-Gee impressed.
An unparalleled 64 strokes, eight under par, gave her not only a new course record but a five-stroke lead to the next player.
Day two went well, although not as superior, but three under par in the second round guarantees her continued lead and increases the lead to six strokes.
- I think 69 strokes is a good result.
Before I started, I did not want to think about yesterday.
It was almost a perfect round that I had on Thursday, says Chun-In-Gee according to Reuters.
New Zealander Lydia Ko and American Jennifer Kupcho are chasing a split second place.
Anna Nordqvist best Swedish
The Swede who was responsible for the best second round was Anna Nordqvist.
After going the first round of three over par, Nordqvist may not have been happy - but she followed up in the best way.
On Friday's 18 holes, there were four birdies but unfortunately also a bogey.
The result still means that she is in pairs and together with a large gang in a shared place 27.
Madelene Sagström was the best of the Swedes on Thursday, one over par, but had it all the tougher in the second round.
She started right away with a double bogey, never recovered and went around on 74 strokes - three over par in total.
However, Pernilla Lindberg, Frida Kinhult and Linnea Johansson will not be allowed to continue playing.
Lindberg went around on 74 strokes and has a score of five over par.
Kinhult accounted for a strong second round but is still six over par.
Johansson finishes with a total of eight over par.
