The short answer is that they need to turn 4 by the end of the baseball calendar year, so by December 31st. The longer answer is the minimum age and when they are ready. Not every child is ready at 4 and while we encourage you to encourage them, sometimes we need to wait a year to start. Forcing your child to start to early is never a good idea.
Also not every child starts in T-Ball. If your child has never played and wants to join at an older age, we welcome them as we have several divisions from which they can join.
