Kirk is nine shots off the pace of South Korean, Mi Jung Hur but, having missed three of her last four cuts, it is an encouraging start for the 37-year old.
Su Oh was unable to maintain the brilliance of her opening 65 and slipped to 24th place with a round of 73, most of the damage today coming with a triple bogey at her 13th hole.
Hannah Green also produced a round of 73 and finds herself in 41st place while Minjee Lee only just made the cut on the number after rounds of 69 and 73.
The leader, Hur, has been a two-time winner on the LPGA Tour but it has been five years since her last victory which came five years after her first. Interestingly, her best finishes since her last win came at this event in 2017 when runner-up.
Hur leads by two over Moriya Jutanugarn with another two shots back to current US Women's Open Champion, Jeongeun Lee6, and the powerful Anne van Dam.
