Vaidisova was 53 days away from her 14th birthday at the beginning of Acapulco 2004, so if the stats are right I think she beats both Graf and Capriati in the age stakes.
Although, Capriati's run as a 13 year old in Boca Raton looks truly unbelievable looking back at it today, with a final and wins over two top 10 players.
Vaidisova was born in 1989 so in early 2004, she was 14 going on 15. Her listing in that ranking looks out of place because the AER changed in the 90s. She was one of the youngest to win a title though, I think.
I was impressed by Madison when I saw her on stream at US Open qualies.
I think she should do well next season.
I expect Donna to enter top 100 at the start of year and then it will be interesting if she can consolidate on her ranking.
All these girls are very young still and things can go very wrong for either of them so any kind of predictions can turn out to be wrong.
It's nice to see so many young players do well and I wish they all could have success in 2013 to spice up the tour!
She may lack experience, but she's brimming with self-confidence:
''I want to become No. 1 in the world and be the best player. I think I have a good chance of achieving that,'' she says. ''I'm a pretty aggressive player, I have good footwork, I have a lot of strengths. I like to come up to the net sometimes and mix up the play.''
I stumbled upon her, because she is coached by former Czech Wimbledon junior champ Andrea Strnadová, who married Jason Stoltenberg.
