While there are many female players in their late teens and 20's playing on the WTA Tour, 2010 so far has proven to be a place for the mid and late 20's ladies.
Serena Williams, 28 years old, and Justine Henin, 28 years old, started the season out playing the final of the Australian Open.
Now, at the French Open, Francesca Schiavone, 29 years old, and Samanth Stosur, 26 years old, are going to play the final this Saturday.
The last woman player under the age of 21 to win a slam was Ana Ivanovic, at the French Open, two years ago, at the age of 20.
