Take a good look at this version of the Yahoo! Sports Power Rankings because our list of the current players to watch in women's tennis could soon be very different.
Vera Zvonareva is also likely to re-enter the list once her physical problems are dealt with and hopes to recapture her excellent early season form.
One player who looks to be here to stay is Caroline Wozniacki, the exciting 18-year-old Danish sensation who is beating a path toward the top.
Wozniacki reached the final last week in Madrid, before losing to Dinara Safina.
Safina rises to the top spot for the first time this week, surpassing Serena Williams, largely due to serious doubts about the American star's fitness. (Prior rankings are in parentheses.)
