Re: 90's - Wozniacki, Cirstea, Cornet, Kvitova, U.Rad'ka, Voegele, Morita, Sevatsova
Playing are taking longer to develop than was the case 10, 20 even 5 years ago. So we really can throw out the "if you haven't won a slam by 20 you are not going to win one" logic. Look at the current generation. We currently have only 3 Grand Slam champions under the age of 26. The Williams sisters and the Belgium girls aren't going to be around for ever. Nor do Sharapova, Kuznetsova or Ivanovic look to me to be players who are going to rack up a huge amount of addition Slams. At some point the younger generation is going to take over. But the thing is, the younger generation isn't going to be so young when it happens.
Could this generation be superceded by an even younger more talented generation? Yes it could. But it sure doesn't look on the cards right now. The age at which players are normally breaking into the top 100 is increasing all the time and the 15 to 17 year olds emerging onto the circuit right now certainly don't appear to be any better than the 18 to 21 year olds.
None of this means any of the players named in thread title is assured of winning a Slam, although I suspect one or two might. I also wouldn't dismiss the chances of the many talented 19, 20 and 21 year olds in the game right now. Infact I wouldn't rule out any player winning a first Slam solely on the basis of age until they are at least 25. And even then, well, I think a few of us still think Elena Dementieva is still in with a chance for at least another year or so. To conclude I suspect there are at least one or two future Slam winners aged 18 to 21 lurking out there, that most of us, myself included, have simply overlooked, who will suprise a lot of people in the future.
