When the first-ever official Women's World Golf Rankings were unveiled in February 2006, Sörenstam was confirmed as the number-one player in women's golf, a position she relinquished to Lorena Ochoa on 22 April 2007. In partnership with Liselotte Neumann in team Sweden, she won the Women's World Cup of Golf, opened her LPGA season with a defence of her title in the MasterCard Classic. She then went winless in eight starts, causing some to talk of a slump. Her winning drought ended at the U.S. Women's Open, where she won an 18-hole playoff over Pat Hurst for her tenth major championship title, tying her for third on the list of players with most major championship titles. She totalled 3 wins on the LPGA and two on the Ladies European Tour, the inaugural Dubai Ladies Masters and the Swedish tournament she hosts, which she defended in her home town at the course where she learned to play. Her International team lost the second Lexus Cup competition to Team Asia.
