After her retirement from competitive golf on the regular tour, she came back, playing on the women's senior tour, the Legends Tour, primarily in the senior majors, with great success. She tied for third in the inaugural Senior LPGA Championship in 2017 and improved that by finishing tied second at the 2018 Senior LPGA Championship. She won both of the two senior ladies major championships in 2019, the U.S. Senior Women's Open and the Senior LPGA Championship, completing the same "senior slam" as Laura Davies achieved in 2018.
