With her win yesterday in the Australian Women's Open, Ya Ni Tseng jumped 3 spots in this week's Rolex Rankings to #2, only .37 points behind Ji-Yai Shin. Only .02 points separate #3 Cristie Kerr from #5 Na Yeon Choi, and #6 Ai Miyazato is still less than a point behind Tseng, so you know we're going to be seeing some serious volatility at the very top of the world of women's golf this winter.
With Angela Stanford, Momoko Ueda, and Amanda Blumenherst joining in the fun this week at the ANZ RACV Ladies Masters and just about everyone from the Open (except 13-year-old Lydia Ko, it appears) returning (including defending champion Karrie Webb, who just moved up to #14 in the world this week), it'll almost make up for the loss of Ji-Yai Shin from the field in terms of Rolex points at stake, but the world #1's unexpected absence will definitely cause a little bit of a buzz deficit Down Under. Let me see if I can find out from Dean Herden why Shin's name isn't on the field list.
