Sörenstam started 2007 by losing a playoff while defending of her MasterCard Classic title. At the Kraft Nabisco Championship she shot her highest 72-hole score in a major in nine years, a result explained by her subsequent diagnosis with ruptured and bulging discs in her neck, the first major injury in Sörenstam's 13-year LPGA career. After a two-month injury rehabilitation break, Sörenstam returned as the Ginn Tribute tournament hostess where she admitted to being at only 85% fitness and finished tied for 36th place. She was still not fully fit in her next two tournaments, the LPGA Championship where she finished tied for 15th place, and the US Women's Open, where, as defending champion, she finished tied for 32nd.
