CME Group Tour Championship: LPGA rotating at top spot without dominant player

When what is now the Rolex Rankings for women's golfers started in 2006, the No. 1 spot was in strong hands. Annika Sorenstam grabbed it and held it for 60 weeks. When she retired in 2008, she left it in even stronger hands. Lorena Ochoa had it for a whopping 158 weeks -- just over three years.
