The 26-year-old finished the first round at one over par, but on Friday, things went much better for Stark. The Swede shot five under par and is at -4 overall after two rounds.
Her great Friday means that Stark has climbed 64 places and is tied for sixth, with a few players left on the course.
South Korea's Ina Yoon leads at -9 at the time of writing.
