It doesn't count to her age restriction, it's not an event which she can earn ranking points. It's just an exhibition event, although it's arguably the most important exhibition tournament, there's a lot of prize money on offer. Some people say it's the only exhibition that Serena takes seriously
The only negative is she can't get any ranking points
But seeing as it doesn't count to her age restriction I guess she can just play an extra tournament later in the year
The eight women who are scheduled to play are: Venus, Ivanovic, Schiavone, Petkovic, Medina Garrigues, Dellacqua, Scheepers and Johansson. Obviously one of those is no longer playing. I think if Donna repeats her Tashkent form she can beat Dellacqua and Johansson, maybe take sets from Scheepers and Medina Garrigues.
A Venus/Donna match would be a dream for tennismaster8820
Probably for Donna too, but her chances would be very slim
