Was the kid any good? I know it takes a while for some kids to 'catch' up with their own size. I mean when it comes to their hand eye coordination and such.
Thats why some really big kids seem goofy. They just haven't adapted to their body due to their growth rates.
Until we find out, I would recommend not parking your car behind center field at the little league ballparks he plays at.
My husband would know if he played well. Not I. But I did watch him at bat once, and he was walked. My husband kept saying, "Look, he's towering over the ump!" I think he may have to be careful to watch his weight, though. Then I think he was playing first base, but I didn't see him make any plays.
Btw, a pitcher on the same team was 6'3" and he had a goatee. (I'm not suggesting their ages are questionable, just pointing out how vastly different boys can be from each other at that age).
