What year are we in for CW Cricket, and does it matter with regard to player ages?
If you are trying to be accurate with real life current players, you have picked a tough one with SA. Most of the players are pretty low profile. Very few will play for a Franchise team and most will be just out of School Cricket (which is where they play a lot of their top level cricket). Also you would have to get the quota system correct, with 6-7 of the 14 man squad being players of colour. This is tough without access to photos.
This will be the best place to start.
39 man squad for the 2008 U19 WC. But Im guessing some of them will be very young.

This is also useful. A list of the current SA Schools U'19s and SA Colts U'19s

Also, all of this years U'19 WC squad are still under 20. With Brett Thompson, Wayne Parnelle, Richard Levi and Craig Kieswetter are all still under 19.
Good luck with it, and I hope after giving you this info I get picked
