My girlfriend's little brother is 5 and kicks ass at all sports... it's amazing. Hockey, baseball, soccer, basketball, football... he just dominates. I was playing catch with him a few months ago, and as we got going, he was throwing really really hard, enough to sting through my glove. Then I started throwing harder to him, and got to almost my limit before backing off. I was amazed.

For his birthday, his dad built a baseball diamond in the back yard. It's got a backstop, fence, everything. And be built this cool gadget out of PVC that has a few bends in it and drops the ball, so you can hit it. You drop the ball in the top, and it bangs around in there for a few seconds, then falls out and you have to hit it. It gives you just a split second to see the ball and swing, and it's pretty hard to anticipate when it'll come out. It really helps with the whole hand-eye coordination thing.
