New Zealand golfer Lydia Ko has comfortably made the cut at the US Open, easing through to a share of 29th place with 10 others after two rounds.
The world No.1-ranked amateur carded an even par 72 in her second round after opening with a two-over par 74 on the notoriously tough Blackwolf Run Golf Club in Wisconsin.
Norway's Suzann Pettersen leads after two rounds, backing up her opening 71 with a second-round 68 on Saturday.
United States golfer Michelle Wie lies second on 130 after firing 66 in her second round, the third-lowest second-round score in the championship's history. She needed only 23 putts.
Ko had targeted an even-par second round, and said she felt much more comfortable on the greens.
"It was much better today... my putting was rolling well," she said, after admitting to struggling on Friday.
"The first three holes, my hands were shaking I was so nervous and I was trying to line up my putts but I couldn't get it straight."
Ko says adjusting to the relentless heat is challenging.
"I am just trying to keep cool - I have had a wet towel on me, and I'm using an umbrella to stay cool as much as possible."
Ko is the leading amateur, holding a two-shot lead over American Emma Talley. She's taking each round in her stride as she mixes with the best women golfers in the world.
"I think just playing along with the pros, that is a positive for me and I am here for experience.
"I am not going to be fully stressed about it - hopefully I will be able to play with some great players and just enjoy it."
